EXECUTIVE SUMMARY

EXECUTIVE SUMMARY The Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP or Plan) is a comprehensive, multi-jurisdictional plan that conserves vulnerable plant and animal species and associated habitats in western Riverside County. The Plan was approved in 2003 and the permits were issued on June 22, 2004 by the U.S. Fish and Wildlife Service (USFWS) and California Department of Fish and Wildlife (CDFW). The MSHCP Planning Area encompasses approximately 1.26 million acres in western Riverside County. The Plan calls for the conservation and management of approximately 500,000 acres within the Plan Area. Of the 500,000 acres, approximately 347,000 acres of land within Public/Quasi-Public (PQP) ownership came into the Reserve at inception of the MSHCP in 2004. Achievement of the 500,000-acre goal depends on conservation of an additional 153,000 acres within the Plan Area that would occur through federal, state, and locally funded acquisitions.

The Western Riverside County Regional Conservation Authority (RCA) was formed in January 2004 and assumed administration and implementation responsibility for the MSHCP in March 2004. The MSHCP requires that the RCA prepare and submit a report of its annual activities. This report provides a summary of activities for the reporting period of January 1, 2019 through December 31, 2019. This is the 15th annual report that covers a full calendar year of Plan implementation.

The 2019 Annual Report provides a means of evaluating the effectiveness of MSHCP implementation and the success of the RCA during the year.

The reporting period for this annual report continues to reflect the state of the economy both locally and nationally. Western Riverside County has seen building activity severely curtailed earlier in the decade, but as the economy got stronger, the RCA started to see more permits and fees from the cities. The RCA will continue its efforts in the next year to acquire critical vegetation communities and build linkages.

The RCA will continue to evaluate losses and gains for the reporting period and set acquisition priorities when possible within different Rough Step Units. Permittee actions regarding the permitting process affect the Rough Step reporting of Reserve Assembly and the acquisition of Reserve Lands. As development activity increases, the need for adherence to proper permitting procedures becomes more important. Other important factors that the RCA considers when making acquisitions is how the acquisition will impact the assembly of Cores and Linkages in a biologically meaningful way.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) ES-1 EXECUTIVE SUMMARY

Reporting Requirements In addition to reporting the amount of habitat conserved and developed during the reporting period, this report includes other information that measures MSHCP progress. At a minimum, the MSHCP specifies that the annual report include:

• Reserve Assembly activities in relation to the Rough Step formulas presented in Section 6.7 of the MSHCP (Volume 1) and in accordance with Species-Specific Objective 1B of the Delhi sands flower-loving fly. • Acres authorized for disturbance within the Plan Area during the reporting period. • Single-family and mobile home activity within the Criteria Area for the year and cumulatively since inception of the Plan occurring under the Expedited Review Process (ERP) for these activities presented in Section 6.1.1 of the MSHCP (Volume 1). • New or expanded agricultural operations within the Criteria Area for the preceding year and cumulatively occurring under the processes identified in Section 6.2 of the MSHCP (Volume 1). • Minor administrative/clerical amendments approved during the reporting period in accordance with the procedures described in Section 6.10.2 of the MSHCP (Volume 1). • Ongoing management and monitoring activities highlighting issues of concern and proposed remedies/actions. • Documentation concerning funding/collection of mitigation fees.

Major Activities in 2019 During 2019, the RCA focused on the following:

(1) In 2019, a total of 1,481 acres were acquired, donated, or obtained through the local development process. The total of Additional Reserve Lands (ARL) acquired for conservation under the Plan through 2019 equals 61,815 acres.

(2) The RCA continued Joint Project Reviews (JPR) for projects being processed by Permittees within the Criteria Area.

(3) The RCA updated its GIS database through 2019, identifying 13,478 acres that have been designated as dedications for future ARL through the JPR process for development.

(4) The RCA and its partners continued the Monitoring and Management Programs.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) ES-2 EXECUTIVE SUMMARY

(5) The RCA continued offering training for Permittees and Consultants.

(6) In 2019, Rough Step Unit 5 – Riparian Scrub, Woodland, Forest vegetation became out of step.

(7) Riversidean Alluvial Fan Sage Scrub vegetation continues to be out of step in Rough Step Unit 3.

(8) Riversidean Alluvial Fan Sage Scrub vegetation continues to be out of step in Rough Step Unit 7.

(9) Grassland vegetation continues to be out of step in Rough Step Unit 8.

Reserve Assembly Summary The MSHCP will ultimately create a 500,000-acre Reserve of protected open space within western Riverside County. In order to build the Reserve from the 347,000 acres of conserved lands in Public/Quasi-Public ownership at the time the MSHCP was adopted (PQP lands), an additional 153,000 acres of land will be conserved within the “Criteria Area.” Since the MSHCP was adopted, the RCA and Permittees have conserved a total of 61,815 acres and expended a total of $526,938,927, not including donation values for Conservation, as shown in the next two figures. In 2019, an additional 1,481 acres were added to the Reserve.

Rough Step Summary The “Rough Step” tool is one way to measure the performance of the MSHCP. The purpose of Rough Step is to help direct conservation of vegetation communities with similar weather patterns, geographies, soils, and geologies as development occurs. The Rough Step measure is intended to ensure that conservation efforts are in balance with development. The Rough Step analysis functions as a signal where development is outpacing conservation and where conservation efforts

therefore need to be focused. All Rough Step analyses is based on the 1994 baseline vegetation mapping used to develop the MSHCP and take allowances for species.

At the beginning of 2019, 34 of 37 vegetation categories were in Rough Step. In 2019, the RCA acquired additional acreage in critical vegetation communities for Rough Step, developed more detailed procedures to reconcile specific vegetation types that were out of Rough Step, and reviewed development projects to determine if losses had actually occurred on those projects. The loss of Riparian Scrub, Woodland, Forest vegetation in Rough Step Unit 5 was caused by a single-family home grading permit on a parcel. The Riversidean Alluvial Fan Sage Scrub vegetation category remains out of Rough Step in units 3 and 7, but the RCA is actively seeking to bring it back into Rough Step. Grasslands in Rough Step Unit 8 have been out of Rough Step due to issues during Plan implementation. The RCA will continue to work toward acquiring properties with the appropriate vegetation category to address Rough Step Units that are not currently in balance.

Reserve Management In 2019, the RCA continued its security, protection, and enhancement of existing and new lands brought into the MSHCP Reserve. At the end of 2019, the RCA was managing over 41,000 acres of conservation lands. The RCA utilizes a contract with the Riverside County Regional Park and Open-Space District (District) to manage the RCA properties. Activities during the reporting period focused on the establishment and maintenance of access controls in high trespass areas, installation of fencing and gates, evaluation of newly acquired lands, weed abatement for fire, enhancement of burrowing owl habitat, and coordination with other management entities.

Management activities for the MSHCP occur on two levels: habitat/landscape-based and species- specific based. The MSHCP Management Team focuses on the balance between managing the overall landscape of the future 500,000-acre Reserve, along with making sure that specific species requirements are also met. In 2019, MSHCP Reserve Management practices incorporated limited Adaptive Management methodologies to improve habitat or species knowledge (e.g., burrowing owl habitat management in the Hidden Valley Wildlife Area, habitat restoration maintenance at CALMAT, Eastern Municipal Water District San Jacinto River vegetation management for small mammals and, seasonal pool enhancements). As the MSHCP Reserve builds out and as the Monitoring Program data is more complete, MSHCP Reserve Managers will be able to develop and incorporate additional Adaptive Management activities.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) ES-6 EXECUTIVE SUMMARY

Biological Monitoring Program The overall goal of the Biological Monitoring Program (Monitoring Program) is to collect data on the 146 Covered Species and associated vegetation communities to assess the MSHCP’s effectiveness at meeting conservation objectives and provide information to the Adaptive Management Program. The Species Accounts in the MSHCP (Volume 2) includes species-specific objectives that are intended to provide for the long-term conservation of all Covered Species. Species objectives influence the type and intensity of monitoring that is conducted by the Monitoring Program. Management decisions or actions are triggered if species objectives or MSHCP goals are not met.

The MSHCP and its associated Implementing Agreement originally designated the CDFW to serve as the Monitoring Program Administrator for the first eight (8) years of MSHCP implementation. In 2010, the RCA began funding the Monitoring Program Administrator position, and at the end of Fiscal Year 2011/12 when the State Wildlife Grant ended, the RCA assumed funding the entire Monitoring Program. Transition from inventory phase to long-term monitoring phase continued in 2019, but with primary focus on rotational long-term monitoring. For species with more frequent reporting requirements, such as Quino checkerspot butterfly (annual) or coastal California gnatcatcher (every three years), long-term monitoring is already in place. For species with longer cycle reporting requirements, such as Los Angeles pocket mouse (every eight years), and with species-specific monitoring objectives requiring significant development and testing, the transition from inventory phase to long-term monitoring phase is ongoing.

The strategy for long-term monitoring includes survey protocols that maximize efficiency by collecting information on multiple species where possible. For example, bird species co-occurring in similar habitat (e.g., willow riparian) during the breeding season can be detected using the same protocol. Some Covered Species occur in isolated pockets within the Conservation Area or are difficult to detect using standard survey protocols (e.g., Delhi sands flower-loving fly). Focused surveys are required for these species. The Monitoring Program also makes use of species habitat models to the fullest extent possible to make surveys optimally efficient and to collaborate with partnering agencies conducting relevant research or monitoring for Covered Species to avoid overlapping efforts.

In 2019, the Monitoring Program recorded, either through focused surveys or incidental detections, 94 of 146 Covered Species. Since June 2004, a total of 141 of 146 Covered Species have been detected in the Conservation Area (135 as a result of focused Monitoring Program surveys, five incidentally observed by Monitoring Program biologists, and one additional Covered Species reported by partnering agencies).

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) ES-7 1.0 INTRODUCTION

1. INTRODUCTION 1.1. Overview of the Plan The Western Riverside County MSHCP (the Plan) is a comprehensive, multi-jurisdictional plan that conserves species and associated habitats to address biological diversity and ecological conservation needs protected by the federal and state Endangered Species Acts (ESAs) as well as the California Environmental Quality Act (CEQA), while streamlining development approvals in western Riverside County. The Plan was approved, and permits were issued on June 22, 2004 by the USFWS and CDFW. The MSHCP Plan Area encompasses approximately 1.26 million acres (approximately 1,967 square miles) in western Riverside County. This Plan includes all land west of the crest of the San Jacinto Mountains and east of the Orange/Riverside County lines. The northern border of the Plan Area consists of the Riverside/San Bernardino County line, and the southern border consists of the Riverside/San Diego County line. The Plan Area includes all unincorporated County of Riverside land within this geographic area, as well as the incorporated cities of Banning, Beaumont, Calimesa, Canyon Lake, Corona, Eastvale, Hemet, Jurupa Valley, Lake Elsinore, Menifee, Moreno Valley, Murrieta, Norco, Perris, Riverside, San Jacinto, Temecula, and Wildomar. The Plan is the largest HCP ever attempted and covers multiple species and multiple habitats within a diverse landscape from urban cities to undeveloped foothills and montane forests. Bioregions within the Plan Area include the Santa Ana Mountains, Riverside Lowlands, San Jacinto Foothills, San Jacinto Mountains, Agua Tibia Mountains, Desert Transition, and San Bernardino Mountains.

The MSHCP calls for the conservation and management of approximately 500,000 acres of the 1.26 million-acre Plan Area. Of the 500,000 acres, 347,000 acres were in Public/Quasi-Public ownership at the time the plan was adopted. Achievement of the 500,000-acre goal depends on conservation of an additional 153,000 acres within the Plan Area. The acquisition of the 153,000 acres of Additional Reserve Lands (ARL) has been ongoing since 2000 (prior to Plan approval). This Plan was developed in conjunction with the CDFW; the USFWS; multiple local jurisdictions; various state, federal and local agencies; and public interest groups/stakeholders.

The Western Riverside County RCA administers the MSHCP. The RCA is a Joint Powers Authority (JPA) responsible for acquiring acres necessary for meeting Plan goals, managing, and monitoring the 153,000-acre Additional Reserve Lands, overseeing Plan compliance, and assisting with MSHCP implementation across the Plan Area.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 1-1 1.0 INTRODUCTION

1.2. Reporting Requirements

The MSHCP requires that the RCA prepare and submit a report of its annual activities. This report provides a summary of MSHCP implementation activities for the 15th full year of RCA operation: January 1, 2019 through December 31, 2019.

Per the MSHCP, the annual report must include a description of:

• Reserve Assembly activities in relation to the Rough Step formula presented in Section 6.7 of the MSHCP (Volume 1) and as revised in Minor Amendment 2007-01. The Rough Step is a tool to help direct conservation within vegetation communities of similar weather patterns, geographies, soils, and geologies as development occurs. It is intended to identify where development is proceeding at a pace that would preclude achieving the conservation goals for specific key vegetation communities. • Acres authorized for disturbance within the Plan Area during the reporting period. The Rough Step, Area Plan, Subunit, and Jurisdictional performance measures use the total acreage authorized for development as well as the total acres conserved in each reporting year. The number of acres authorized for disturbance and the acres conserved allows the RCA and Permittees to determine the rate of development and conservation occurring in distinct geographic areas. • New single-family and mobile home activity on existing parcels of land within the Criteria Area for the reporting year and cumulatively occurring under the Expedited Review Process (ERP) for these activities presented in Section 6.1.1 of the MSHCP (Volume 1). Applications for a single-family home grading permit or for a mobile home site preparation permit on existing parcels of land within the Criteria Area are subject to review against the MSHCP conservation criteria to determine the least-sensitive location for the building pad and necessary access roadways. This review process is referred to as the ERP and, with approval under this process, applicable properties are referred to as “ERPs.” The MSHCP included ERP activity assumptions (i.e., number of permits and acres disturbed) (Section 7.3.2 of the MSHCP, Volume 1). The annual reporting process is used to determine whether ERP activity is occurring in a manner that is consistent with the assumptions made during MSHCP development. Furthermore, an analysis of ERP activity allows the RCA to determine if Reserve Assembly within the Criteria Area is being adversely impacted as a result of this provision. Refer to Section 4.1 for more information. • New or expanded commercial agricultural operations within the Criteria Area for the reporting year and cumulatively occurring under the processes identified in Section 6.2 of the MSHCP (Volume 1). Existing agricultural uses and conversion of natural lands to

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 1-2 1.0 INTRODUCTION

agricultural use are allowed as Covered Activities within the Criteria Area (Section 7.3.3 of the MSHCP [Volume I]). New conversions to agricultural use within the Criteria Area are covered up to an established threshold of 10,000 acres over the life of the Plan. The annual reporting process is used to establish this initial threshold, to periodically measure new commercial agricultural activities against it, and to analyze potential impacts to Reserve Assembly associated with these new agricultural activities. • Minor Administrative/Clerical Amendments approved in accordance with the procedures described in Section 6.10.2 of the MSHCP (Volume 1). The annual report provides a method to officially document such amendments. • Ongoing management and monitoring activities highlighting issues of concern and proposed remedies/actions. These items are included in the annual report to give insight into these efforts. • Documentation concerning funding/collection of the Local Development Mitigation Fees to provide insight into management of partial local funding resources available.

1.3. Methods

RCA staff work with each Local Permittee (the 18 cities and County of Riverside) to build a GIS database of relevant conservation and development activity, which is used to calculate performance measures. For annual reporting purposes, conservation is counted as a gain when acquired through transfer of title, recordation of conservation easement, or conservation through a MOU (Memorandum of Understanding) with an entity that will manage their property pursuant to the terms of the MSHCP. This annual report reflects the cumulative gains in conservation between February 2000 and December 31, 2019.

Development losses are counted at the time of grading permit issuance. This annual report reflects cumulative losses between June 22, 2004 and December 31, 2019. Losses are usually counted earlier in the development process (at time of grading permit issuance), and gains may be counted at the end of the development process (at time of fee title transfer/conservation easement recordation at the County Recorder’s Office; time of occupancy). Because of this, the amount of habitat losses may appear greater as they are reported before the habitat gains can be reported to offset those losses.

The tracking of development losses is further complicated in some cases by the issuance of grading or building permits on a parcel, but the grading or building is never actually started by the owner of the parcel. Procedures have been developed to review losses from previous years to account for these permits that are issued but never actually result in a loss to the vegetation category. Complete

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 1-4 2.0 HABITAT GAINS

2.0 HABITAT GAINS Habitat gains are the Additional Reserve Lands (ARL) acquired or otherwise permanently protected for Conservation pursuant to the Plan. The MSHCP and coverage for the 146 species identified in the Plan are based on the establishment of a 500,000-acre Conservation Area, of which approximately 347,000 acres were already in public or quasi-public (PQP) ownership when the Plan was adopted. The additional 153,000 acres (500,000 minus 347,000) of ARL are being assembled from a variety of sources including:

• Private land acquisitions through the Habitat Acquisition Negotiation Strategy (HANS) process • Acquisitions from willing sellers • Donations of fee title or conservation easements • Entities with Conservation Lands managed pursuant to the MSHCP with a MOU (Memorandum of Understanding) between the Entity and the RCA.

As of December 31, 2019, 61,815 acres have been acquired as ARL for Conservation within the Plan Area. Habitat gains are the Reserve lands acquired or otherwise permanently protected for conservation pursuant to the Plan through the various methods listed above. Cumulative habitat gains (or conservation) are reported from the period February 2000 through December 31, 2019. February 2000 is used as the start of the gain reporting period because in anticipation of MSHCP permit issuance the County, CDFW, California Department of Parks and Recreation, and the USFWS, began an early, aggressive campaign to assemble the ARL prior to Plan permit issuance.

In 2012, a policy on conserved lands outside of Criteria Cells counting as Additional Reserve Lands and toward Rough Step analysis was developed in consultation with the Wildlife Agencies. The policy allows lands outside Criteria Cells to be counted under certain circumstances with Wildlife Agency concurrence. In general, the lands must be biologically valuable and occur directly adjacent to existing ARL within Criteria Cells.

2.1. Conservation Summary

In 2019, a total of 1,481 acres of ARL were acquired, donated, or obtained through the local development process. Cumulatively, as of December 31, 2019, a total of 60,819 acres of ARL has been conserved for purposes of habitat and species conservation. Table 2-1, MSHCP Conservation Summary, provides a snapshot of the conservation activity completed through December 31, 2019.

The changes are mainly due to accounting for some lands that were acquired outside of Criteria Cells and corrections to acreage totals for selected acquisitions. ** Totals may not add up due to rounding. # The Lockheed Potrero MARB SKR acquisition (2,540 acres) is included in this total. A total of 1,190 acres was acquired outside of the Criteria Cells.

Many of the covered species and associated sensitive habitats are located on federal and state lands. For these reasons, existing federal and state lands were included in the existing 347,000 acres of Public/Quasi-Public lands (PQP). Pursuant to the Plan, conservation gains toward the 153,000 acres of ARL are shared amongst the federal, state, and local permittees. The contributions by federal, state, and local entities are shown in Figure 2-1, Total Cumulative Acreage Contribution by Federal, State, and Local Jurisdictions.

Figure 2-1 Total Cumulative Acreage Contributions Federal, State, and Local Jurisdictions

Federal 9,199 Acres

State 12,409 Acres

Local 40,212 Acres

As of December 31, 2019, the federal agencies have contributed 9,199 acres toward the 153,000- acre ARL Conservation goal of the MSHCP. The State agencies have contributed 12,409 acres toward the ARL Conservation goal of the MSHCP. The Local Permittee contribution (occurring through recordation of conservation easements, acquisitions from willing sellers, donations, or acquisition of property from private developers through HANS or equivalent process) totaled 40,212 acres toward the ARL Conservation goal of the MSHCP. In 2012, the Wildlife Agencies and RCA developed procedures for the determination of ARL or PQP lands. These procedures are included within the Annual Report media disc.

2.2. Conservation by Jurisdiction

During Plan development, targets to measure Plan performance within municipal jurisdictions were created. Jurisdictional acreage targets were developed for the original 14 cities and the unincorporated County during the preparation of the Plan in 2003. Table 2-2, Conservation Targets by Jurisdiction, provides a conservation summary for 2019, as well as cumulative conservation by jurisdiction (from February 2000 to the end of 2019). New cities and annexations do not have goals under Section 3.3 of the MSHCP (Volume 1) and instead inherit the goals of individual criteria cells that fall within their City jurisdiction, if any. The cities of Moreno Valley and Riverside have exceeded the ARL goal within their jurisdiction and ARL Conservation within Beaumont, Calimesa, and Corona has surpassed the original low-range Conservation acreage goals.

2.3. Conservation by Area Plan

Area Plans are used as an MSHCP performance measure unit to monitor success of Plan implementation. The 16 Area Plans relate to County planning boundaries associated with the Riverside County General Plan.

Table 2-3, ARL Conservation Goals by Area Plan, provides a summary of all ARL conservation achieved to date (February 2000 to December 31, 2019) by Area Plan, as well as the target conservation acreages identified for each Area Plan in Section 3.3 of the MSHCP (Volume 1). In

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 2-4 2.0 HABITAT GAINS

this section of the MSHCP, the target conservation acreages included an overall target conservation acreage (Public/Quasi-Public lands plus Additional Reserve Lands). The low- and high-range targets included in Table 2-3, below reflect only the ARL targets, rather than the overall Area Plan targets. This distinction, for annual reporting purposes, is an additional check-and- balance mechanism for ARL Assembly. The fourth column in Table 2-3, below reports the total acreage conserved during the reporting period (January 1, 2019, to December 31, 2019). The fifth column includes a running total of all ARL conserved within the Area Plan.

2.4. Conservation and Acquisition Trends

RCA, in conjunction with the Permittees, continues to focus its acquisition and conservation efforts toward meeting Rough Step and ARL goals by Area Plan. The RCA strives to gain ARL at the rate of development and to gain the ARL in-step with vegetation community losses through the

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 2-5 2.0 HABITAT GAINS

Rough Step analysis. This can be a difficult balance given existing acquisition funding. For example, the RCA prioritizes acquisitions triggered through the development HANS process as high. This is because there are specific acquisition timelines pursuant to the MSHCP for these types of HANS. The RCA also works with non-development HANS applicants and willing sellers. Additionally, there is the need to assemble linkages and constrained linkages, that does not always improve the Rough Step numbers but is a requirement as part of reserve assembly. The RCA continues to work with local Permittees on obtaining donations through the land development process

2.5. Development Projects and Future Conservation

The HANS process, described in Section 6.1.1 of the MSHCP (Volume 1), and the Joint Project/Acquisition Review process, described in Section 6.6.2.E of the MSHCP (Volume 1), provide several processes for the review of development projects for consistency with the MSHCP. The HANS and Joint Project Reviews (JPR) performed by the Permittees and the RCA, respectively, on proposed development projects are used to determine the impacts to MSHCP covered resources by these projects. The MSHCP designates a total of 41,000 acres to be set aside through dedication (donation) from development projects. The MSHCP projected that from the beginning of the Plan, that each year approximately 1,640 acres would be conserved as dedication through the development process. In retrospect, this estimate was too aggressive and did not account for the extended time between development project approvals and commencement of construction, or the use of fee credits.

The JPR database was first developed prior to the adoption of the MSHCP and permit issuance but has been refined over the years. During the JPR and HANS review processes, a development footprint and proposed areas for conservation are designated within the project area for each project. These designated areas are stored in a JPR database as Proposed MSHCP Conserved Lands and Proposed MSHCP Conservation Easements. The JPR database also includes projects that were designated as 100% conservation.

As of December 31, 2019, a total of 13,478 acres are currently designated as future ARL conservation dedications that will occur from development. This future conservation has not been applied to the Rough Step Analysis but does serve to provide an indication of conservation that will be acquired through the development process in the future. Some projects that include areas of conservation may not be completed for a considerable amount of time.

3.0 HABITAT LOSSES

The MSHCP calls for the establishment of a 500,000-acre Conservation Area, of which approximately 347,000 acres are in Public/Quasi-Public (PQP) ownership. The remaining 153,000 acres of ARL will be assembled primarily from private land acquisitions, donations, and through the land development entitlement process.

As the Reserve is assembled, habitat is lost due to development, construction of infrastructure, and other activities. Habitat gains as defined for the purposes of this section are the ARL acquired since February 2000, when the County, CDFW, California Department of Parks and Recreation, and the USFWS, in anticipation of MSHCP permit issuance, began an early, aggressive, campaign to assemble the Reserve prior to Plan permit issuance. Since the Plan’s state and federal permits were not issued until June 22, 2004, tracking habitat losses did not begin until that day.

This chapter is devoted to summarizing all habitat “losses” that have occurred between Plan adoption and December 31, 2019 as well as Rough Step analysis. Rough Step analysis is one of the MSHCP performance measures and is a Reserve Assembly accounting process to monitor ARL conservation and loss of specified habitats within the Criteria Area. Basically, Rough Step measures whether conservation gains occur in-step with losses from development in terms of acreage, geography, and habitat.

3.1. Habitat Loss Summary

Development Activity

It is important to note whether losses occur within the MSHCP Criteria Area (where the ultimate 153,000-acre ARL is envisioned to be assembled) or outside of the Criteria Area. Because the Criteria Area totals approximately 300,000 acres, the MSHCP assumed a portion of the area within the Criteria Area would be developed but that most habitat losses would occur outside of the Criteria Cells. During 2019, a total of 2,136 acres were approved for development throughout the Plan Area and these are counted as habitat losses. Of this amount, 1,829 acres were lost outside the Criteria Area and 306 acres were lost within Criteria Area (Criteria Cells). Table 3-1, Habitat Loss by Jurisdiction (January 1, 2019 – December 31, 2019), and Table 3-2, Habitat Losses by Jurisdiction Cumulative (June 22, 2004 – December 31, 2019), provide summaries of the total new losses that have occurred during 2019 and since Plan inception, respectively.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 3-1 3.0 HABITAT LOSSES

Table 3-1 lists grading/building permits issued by Permittees between January 1 and December 31, 2019 that are new losses to the MSHCP. Multiple types of permits (e.g., building, grading) were issued by the Permittees for various types of land development activities in this and previous years. However, for MSHCP annual reporting purposes, multiple permits issued on one parcel were summarized into one permit and counted as one loss.

As indicated above, County of Riverside approved the largest number of permits affecting the largest area, which is to be expected, given its geographic area of 988,000 acres within the 1.26- million-acre Plan Area. These tables show that in 2019 (Table 3-1) 86% and cumulatively (Table 3-2) 81% of the development occurred outside of the Criteria Areas, which means the majority of losses are not occurring within the areas considered for Conservation.

Agricultural Activities

Existing agricultural uses and conversion of natural lands to agricultural use are Covered Activities within the MSHCP boundaries. Establishment of new agricultural uses specifically within the Criteria Area is a covered activity up to 10,000 acres over the life of the Plan. The MSHCP defines

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 3-3 3.0 HABITAT LOSSES

agricultural operations as production of all plants (horticulture), fish farms, animals, and related production activities, including the planting, cultivation and tillage of the soil, dairying, and apiculture, and the production, plowing, seeding, cultivation, growing, harvesting, pasturing, and fallowing for the purpose of crop rotation of any agricultural commodity, including viticulture, apiculture, horticulture, and the breeding, feeding, and raising of livestock, horses, fur-bearing animals, fish, or poultry and all uses conducted as a normal part of such operations, provided such actions are in compliance with all applicable laws and regulations. The RCA established the existing agricultural operations database and reports each year the losses occurring from agricultural activities within the MSHCP.

Agricultural Grading Permits 2019

Agricultural grading permits are issued by the Riverside County Building and Safety Department, and these permits represent conversion of undeveloped land to agricultural uses, as well as additional or new agricultural activities on parcels that had already been in agricultural use. In 2019, there were 77 Agricultural grading permits issued by the County Building and Safety Department. The Agricultural Commissioner did not receive or process any Certificates of Inclusion (COI). The County grading ordinance does not require COIs. All agricultural grading permits were verified to be within the Plan Area. The 77 agricultural grading permits resulted in a combined loss of 1,786 acres. The acres were added to the Agricultural Operations Database.

New Agriculture in Criteria Areas Accounting

Since Plan adoption through December 31, 2019, a total of 2,423 acres within Criteria Cells has been approved through either COIs or Agricultural Grading (refer to Table 3-3).

Agricultural Operations Database Summary

Further details on the process, procedures, and methods to update the Agricultural Operations Database with the COIs and Agricultural Grading permits for the MSHCP are described in the associated GIS metadata files. Table 3-3, Agricultural Grading Summary provides a summary.

The Agricultural Operations Database as updated for the 2019 Annual Report continues to represent 146,535 acres utilized for agricultural purposes as of December 31, 2019.

3.2. Rough Step Summaries

Rough Step is one of the MSHCP performance measures used to monitor success of the MSHCP; however, it does not adequately measure the full success of reserve assembly as it relates to linkages and constrained linkages. Rough Step is a methodology that helps direct acquisition activity within specific vegetation communities of similar weather patterns, geographies, soils, and geologies, as development occurs in specific areas. The Rough Step measure is intended to ensure that conservation of specific, narrowly distributed habitats occurs in “Rough Step” with development approvals. The Rough Step analysis functions as an early warning system to signal where development is outpacing conservation and where future conservation efforts should be focused (refer to Figure 3-1, Western Riverside County MSHCP Rough Step Analysis Units).

Table 3-4, Habitat Losses In/Out of Criteria Area by Rough Step Unit in 2019, summarizes how much development (losses) has taken place inside and outside the Criteria Area during the last year.

Table 3-5, Rough Step Acreage Summary, provides available acreage of key vegetation types on private lands in the Criteria Area by Rough Step (column 3) and Additional Reserve Land goals (column 4). Also included are the total acres conserved through December 31, 2019 (column 5) and the total acres authorized for development by Permittees (column 7). The sixth column includes the allowable development acreage targets by vegetation type for each Rough Step, based on the amount of conservation that has occurred (column 5). Habitat Gains for conservation (column 5) are through December 31, 2019. Allowable development was calculated using losses (derived from grading or building permits) between June 22, 2004 and December 31, 2019. Column 8 shows the difference between where acres authorized for development (column 7) and the allowable development calculated using the Rough Step formula (column 6). Where the difference is negative (red), the vegetation community would be considered out of Rough Step. Detailed Rough Step information by Unit is presented in Sections 3.2.1 through 3.2.9, respectively.

The Delhi Sands Flower-loving Fly is • Delhi Soils are “in” Rough Step found within the fine, sandy Delhi series soils along the northern edge of Rough Step Unit 1. Unlike other covered species, the Permittees were given options for conservation of this species. These options were described in the Delhi Sands Flower-loving Fly species account objectives. As part of the MSHCP Implementing Agreement, the Wildlife Agencies and Riverside County jointly opted to follow Delhi Sands Flower-loving Fly species account Objective 1B in the MSHCP (Volume I). Objective 1B mandates that surveys are to be conducted in areas where suitable habitat exists within the mapped Delhi soils (with the exception of Cells 21, 22, and 55). When the species is present, 75 percent of mapped Delhi soils on-site must be conserved. Within Cells 21, 22, and 55, surveys are not required. Instead for this three-cell area, 50 acres of Additional Reserve Lands with Delhi soils and suitable habitat for the Delhi Sands Flower-loving Fly shall be acquired. Acquisition of the required 50 acres is in process at the RCA. Species Objective 1B includes Rough Step figures to ensure that Additional Reserve Lands are being acquired in Rough Step with development in Cells 21, 22, and 55. Table 3-7, Delhi Soils Rough Step Acreage Analysis (Species Account Objective 1B), provides a summary of the Delhi sands Rough Step acreage analysis.

3.2.9. Rough Step Unit 9

Rough Step Unit 9 is composed of three separate areas within Riverside County. The first area encompasses 80,163 acres within the southwest area of the MSHCP. This portion of the Rough Step Unit consists of mostly Public/Quasi-Public Lands within the Cleveland National Forest forming the coastal mountain range between Southwest Riverside County and Orange County. The second area encompasses 20,975 acres within the northeast area of the MSHCP. This portion of the Rough Step Unit consists of mostly Public/Quasi-Public Lands within the San Bernardino National Forest and the city of Banning north of the Morongo Indian Tribal Lands. The third area encompasses 138,720 acres within the southeast middle portion of the MSHCP. This portion of the Rough Step Unit consists of mostly Public/Quasi-Public Lands within the San Bernardino National Forest but does include the unincorporated areas of Idyllwild and Pine Cove, as well as Garner Valley north of Anza. (See Figure 3-10, Rough Step Unit #9). Rough Step Unit 9 has no key vegetation communities that are tracked through Rough Step. Table 3-15, Rough Step Unit 9 Acreage Totals, provides only acres conserved for non-Rough Step Unit 9 habitats as well as development acreages within this Rough Step Unit.

4.1. Single-Family/Mobile Home Activity

Background

In accordance with existing land use regulations, development of a single-family home or mobile home on an existing legal parcel is a Covered Activity, per Section 7.3.2 of the MSHCP (Volume 1). Single-family home grading/site preparation permits and mobile home site preparation permits on existing legal lots within the Criteria Area are reviewed against the MSHCP Conservation Criteria solely to determine the least sensitive portion of the lot for building pad location. These activities are covered by the Expedited Review Process (ERP) provision of the Property Owner Initiated Habitat Evaluation and Acquisitions Negotiation Process. Section 7.3.2 of the MSHCP (Volume 1) lists several assumptions regarding the predicted annual level of single-family/mobile home activity within the Criteria Area. Based on key assumptions, the MSHCP estimated approximately 75 parcels would utilize the ERP provision within the Criteria Area annually. These parcels were estimated to impact approximately 675 acres of land annually. It was also assumed that, of these 675 acres, half (338 acres) would be within areas considered desirable for inclusion in the MSHCP Conservation Area (i.e., described for conservation). Finally, it was assumed that the Permittees would successfully negotiate conservation on 75% of the 338 acres, leaving 85 acres for single-family/mobile home development. The annual reporting process is used to determine whether ERP activity is occurring in a manner that is consistent with the assumptions made during MSHCP development.

Effect on Reserve Assembly

Between January 1, 2019 and December 31, 2019, 30 single-family/mobile home permits utilized the ERP. These permits covered approximately 80 acres within the Criteria Area. The majority of ERP activities occurred within Rough Step Units 4 and 7. In 2019, an ERP was the cause of Rough Step 5 becoming deficient in the riparian scrub, woodland, forest vegetation community. As critical vegetation categories become scarce due to development, ERPs and single-family homes may play a bigger role in whether a region will maintain its rough step balance.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 4-1 4.0 ACTIVITIES WITHIN PLAN AREA

2019 Work Plan

The RCA will continue working with both the Cities and the County to track single-family home projects using the ERP. The reviews performed in the past, have identified projects as not impacting as many acres of sensitive areas as originally reported by the ERP. The reviews also indicated that projects that were issuing grading or building permits were later abandoned with little or no impact to sensitive areas. The RCA does not remove areas of loss unless a permit is abandoned by the Permittee or Applicant(s).

4.2 Public Works Projects

MSHCP Permittees include the Riverside County Flood Control and Water Conservation District (County Flood), Riverside County Park and Open-Space District (County Parks), Riverside County Waste Management Department, Riverside County Transportation Commission, the 18 cities in western Riverside County, Riverside County, California Department of Transportation (Caltrans), and California Department of Parks and Recreation (State Parks). These agencies’ projects are Covered Activities under the Plan and, in some instances, are subject to Joint Project Review (JPR). JPRs for State Parks and Caltrans are the responsibility of the Wildlife Agencies, while the JPR process for public projects by the other Permittees, as appropriate, is the responsibility of the RCA and the Wildlife Agencies. Table 4-1, Public Works Projects (January 1 through December 31, 2019), summarizes public works project activity during 2019.

4.3 Participating Special Entity Permits

Per Section 6.1.6 of the MSHCP (Volume 1), the RCA may grant MSHCP take authorization to non-signatory public agencies and other regional service providers under the Participating Special Entity (PSE) provision, as described in Section 11.8 of the MSHCP Implementation Agreement. The MSHCP defines “Participating Special Entity” as any regional public facility provider, such as a utility company or a public district or other agency that operates and/or owns land within the MSHCP Plan Area but who is not a MSHCP Permittee and who is granted take authorization.

There were no PSE projects that were started or completed in 2019 however the following came into the RCA for amendment:

• Southern California Edison Valley Ivyglen Subtransmission Line Project, Phase 1

4.4 Criteria Refinement

As indicated in Section 6.6.2F of the MSHCP (Volume 1), Permittees are expected to implement the MSHCP consistent with Cell Criteria. In cases where a Permittee and/or landowner believes that conservation objectives could be achieved in an alternative location or alternative Reserve design scenario, the criteria can be refined to reflect such modification.

For the annual reporting year of 2019, the RCA met with several Permittees about Criteria Refinements being a potential option for proposed developments. The Vine Creek Affordable Housing Project in the City of Temecula was completed in 2019. The Criteria Refinement for the Soboba - Luiseno Village project in the city of San Jacinto has been finalized and pending RCA Board approval in 2020.

4.5 Agency Cooperation

Many of the Covered Species and associated sensitive habitats are located on federal and state lands. For these reasons, existing federal and state lands were included in the existing 347,000 acres of Public/Quasi-Public lands. Assumption for conservation of these lands came with the goal that Memoranda of Understanding (MOU) between these state, federal, and other governmental/quasi-governmental agencies must be established to ensure that lands are managed in concert with Covered Species’ needs.

U.S. Forest Service. Under agreement with the San Bernardino and Cleveland National Forests, MSHCP Monitoring Program biologists have been conducting species surveys in Forest areas since 2005 and continued the process of completing the scheduled initial inventory for species presence (refer to Section 7.2 in this report for more details). Survey information is shared and activities coordinated with Forest and other Reserve Managers within the MSHCP, at monthly Reserve Managers meetings hosted by the Biological Monitoring Program.

Bureau of Land Management (BLM). Lands owned by the Bureau of Land Management (BLM) in western Riverside County contribute to Reserve Assembly as PQP lands. The majority of the BLM lands within the MSHCP are associated with the Riverside County Stephens’ Kangaroo Rat Habitat Conservation Plan (SKR-HCP). The BLM released the revision to their South Coast Resource Management Plan (SCRMP) in June 2011. The RCA entered into an MOU with the BLM (RCA Agreement No. 09002, BLM MOU No.CA-660-08-01) on June 6, 2008 as a cooperating agency on this Plan. Through this MOU, the RCA worked with the BLM to maximize coordination and achieve consistency where practical in the development of the revisions to the SCRMP. When completed and adopted, the revised SCRMP will be the basis for the BLM and RCA to enter into additional MOU discussions to allow Adaptive Management on BLM properties that would be necessary to meet the objectives of the MSHCP's species specific management plans as they evolve following completion of the initial Monitoring Program species inventory. The SCRMP has not yet been adopted by the BLM.

Riverside County Habitat Conservation Agency (RCHCA). The RCHCA is the Joint Powers Authority responsible for implementation of the Stephens’ Kangaroo Rat Habitat Conservation Plan (HCP) in western Riverside County. The RCHCA owns approximately 6,700 acres of conservation land at Estelle Mountain and the Southwest MSR surrounding Lake Skinner and Diamond Valley Lake and manages another 10,000 acres at Southwest MSR. As such, the RCHCA is an important conservation landowner in the MSHCP Plan Area and monitoring/management coordination between the RCHCA and RCA benefit MSHCP Covered Species. The RCHCA allows access for MSHCP biological monitoring purposes.

Riverside Corona Resource Conservation District (RCRCD). In 2010, the RCA and RCRCD entered into a management MOU for properties which RCRCD either holds in fee title or has a conservation easement over. RCRCD manages these lands in a cooperative manner consistent with the goals and objectives of the MSHCP. The RCA and RCRCD also work collaboratively on In Lieu Fee Program related mitigation opportunities on RCA-owned land and on potential acquisitions within RCRCD’s service area.

Inland Empire Resource Conservation District (IERCD). In 2012, the RCA and IERCD entered into a management MOU for properties within the Plan Area which IERCD either holds in fee title or has a conservation easement over. IERCD manages these lands in a cooperative manner consistent with the goals and objectives of the MSHCP. The RCA and IERCD also work collaboratively on In Lieu Fee Program related mitigation opportunities on RCA-owned land.

Temecula-Elsinore-Anza-Murrieta Resource Conservation District (TEAM RCD). In 2019, the RCA and TEAM RCD executed a management MOU for properties within the Plan Area which TEAM RCD either holds in fee title or has a conservation easement over. TEAM RCD manages lands in a cooperative manner consistent with the goals and objectives of the MSHCP. The RCA and TEAM RCD also work collaboratively on In Lieu Fee Program related mitigation opportunities on RCA-owned land.

Rivers & Land Conservancy (RLC). In 2017, the RCA and RLC executed a management MOU for properties which RLC either holds in fee title or has a conservation easement over. RLC manages these lands in a cooperative manner consistent with the goals and objectives of the MSHCP. The RCA and RLC also work collaboratively on In Lieu Fee Program related mitigation opportunities on RCA-owned land.

4.6 Clerical/Minor Amendments to the MSHCP

Clerical Amendments

Section 6.10.1 of the MSHCP (Volume 1) outlines clerical amendments to the MSHCP and associated revision requirements. The MSHCP states that clerical amendments shall be made by the RCA on its own initiative or in response to a written request submitted by any Permittee or Wildlife Agency, which includes documentation supporting the proposed clerical change. Clerical changes shall not require any amendment to the MSHCP, the Permits, or the Implementing Agreement. Clerical changes include corrections of typographical, grammatical, and similar editing errors that do not change the intended meaning and corrections of any maps or exhibits to correct insignificant errors in mapping. It is assumed that most clerical changes to the MSHCP will occur during the first 10 years of MSHCP implementation. Clerical amendments are to be summarized in each annual report and are found in Appendix A of this report.

In 2019, the RCA did not process any clerical amendments.

Minor Amendments

Section 6.10.2 of the MSHCP (Volume 1) outlines minor amendments to the MSHCP and associated revision procedures. The following items are considered minor amendments to the MSHCP and shall be administratively implemented:

(1) Minor corrections to land ownership; (2) Minor revisions to survey, monitoring, reporting, and/or management protocols that clearly do not affect Covered Species or overall MSHCP Conservation Area functions and values; (3) Transfer of target Reserve Assembly acreages between identified subunits within a single Area Plan and/or between Area Plans within a single Rough Step Analysis Unit consistent with the criteria; (4) Application of Take Authorization for development within Cities incorporated within the MSHCP boundaries after the effective date of the Implementing Agreement, assuming such inclusion does not preclude Reserve Assembly, significantly increase the cost of MSHCP Conservation Area management or assembly, or preclude achieving Covered Species conservation and goals; (5) Annexation or de-annexation of property within the Plan Area pursuant to Section 11.5 of the Implementing Agreement, provided such inclusion does not preclude Reserve Assembly, significantly increase the cost of the MSHCP Conservation Area management or assembly, or preclude achieving Covered Species conservation and goals; (6) Minor extension of cut or fill slopes outside of the right-of-way limits analyzed in the MSHCP for covered roadways to accommodate construction in rolling or mountainous terrain; and (7) Updates/corrections to the vegetation map and/or species occurrence data. One minor amendment was processed in 2019.

4.7 Fires, Floods, and Drought

Section 6.8.3 of the MSHCP (Volume 1) discusses Changed Circumstances potentially affecting the MSHCP Conservation Area that include short-interval return fire, floods, drought, and invasion by exotic species. While none of these changed circumstances have occurred, the Annual Report will continue reporting on fires within the MSHCP area. RCA staff started reporting fire activity in 2012.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 4-7 4.0 ACTIVITIES WITHIN PLAN AREA

Short-Interval Return Fire

For the purpose of defining Changed Circumstances, short-interval return fire is defined as fire occurring in the same location as a previous fire within the same footprint more than once in a 5- year period within the MSHCP Conservation Area.

The two largest fires in the MSHCP Plan Area for 2019 were the Tenaja Fire and the Sandalwood Fire. The Tenaja Fire burned approximately 1,940 acres encompassing the northern portions of the Santa Rosa Plateau Ecological Reserve, west of the City of Temecula. Additionally, the RCRCD MOU Addition property and portions of the RLC/La Laguna Estates Conservation Easement also burned. The Sandalwood Fire burned 1,008 acres in northwestern Calimesa, west of Interstate 10 but outside of Conservation Area and outside of Criteria Cells.

4.8 Activities Affecting Reserve Assembly

In consultation with the Wildlife Agencies, this section is meant to provide documentation of actions which have influenced reserve design during the last year. No significant activities occurred in 2019 which influenced reserve design.

6.0 MANAGEMENT ACTIVITIES

6.1 MANAGEMENT ACTIVITIES

6.1. Management Goal

Section 5.2 of the MSHCP (Volume 1) indicates that management’s goal is to “establish and maintain a self-sustaining MSHCP Conservation Area that focuses on conserving habitats and species and is consistent with the conservation objectives for the Covered Species.”

Management activities for the MSHCP occur at two levels: habitat/landscape and species-specific. The MSHCP Management team focuses on the balance between managing the overall landscape of the future Reserve and managing lands to support specific species requirements (refer Table 5-2 of MSHCP [Volume 1]). The key to long term management of the MSHCP Reserve is to incorporate an Adaptive Management approach so that management of habitats and species is flexible and dynamic. As the MSHCP Reserve builds and with feedback from Monitoring Program species occurrence data, MSHCP Reserve Managers develop and incorporate land management techniques to meet the needs of the lands now and into the future.

In the last year, MSHCP Reserve Management has worked with the Monitoring Program to better understand survey data and how to compare and/or correlate data with species-based management activities.

6.2. General Management Activities

Section 5.2.1 of the MSHCP (Volume 1) stipulates that the Reserve Managers and the Reserve Management Oversight Committee (RMOC) identify the priorities for management activities to carry out the species objectives and biological values. In 2009, the RMOC Steering Committee was formed to focus and direct the functions of the RMOC. The RMOC Steering Committee consists of the RCA, USFWS, CDFW, State Parks, and County Parks.

The RCA Reserve Manager established priorities in collaboration with RCA management staff. The following outlines activities that MSHCP Reserve Management staff focused on in 2019 per Section 5.2.1 of the MSHCP (Volume 1):

• Control unauthorized public access (patrol, fencing, gates, signage), trash removal, etc.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 6-1

6.0 MANAGEMENT ACTIVITIES

• Perform initial baseline assessments of newly acquired properties within the first four years of conveyance to the MSHCP. • Maintain acquired lands in conditions similar to or better than when acquired. • Remove non-native invasive species and restore natural habitat using seeding, pole cutting, and/or transplanting. • Conduct fire abatement activities in compliance with County Ordinance 695 or other jurisdictions as applicable to the location of the land.

6.3. Reserve Management Units

The MSHCP contemplated five conceptual management units (refer to Figure 5-1 of the MSHCP [Volume 1]). After Plan adoption, the Reserve Managers created a more detailed breakdown of the management units depicted in the MSHCP. To manage the entire 500,000-acre Reserve in an effective and efficient manner, it was necessary to break up the MSHCP’s five management units into more manageable sizes. The current nine Reserve Habitat Management Units are shown in Figure 6-1. Location and Distribution of the Nine Reserve Habitat Management Units. Although the U.S. Forest Service (Forest Service) Units are part of the 500,000-acre Reserve, they are not assigned a MSHCP Habitat Management Unit because the management of Forest Service lands is dictated by their Land Management Plans.

The MSHCP Management Team has completed management plans for Cactus Valley, Gavilan, and Sage and the draft management plan for the Menifee HMU which will act as the “blueprint” for how the Menifee HMU will be managed. The management plans identify specific habitat or vegetation management methodologies (e.g., burning, mowing, grazing, herbicides, hand clearing or thinning), as well as focus on species-specific management needs.

6.4. Reserve Management Staffing

In addition to RCA management staff, the RCA contracts with Riverside County Regional Park and Open-Space District (Parks District) for reserve management. The Parks District MSHCP Reserve Management Unit in 2019 had 10 full time personnel assigned to the RCA program. These included a Natural Resources Manager who oversees all MSHCP management services; two Natural Resource Specialists, who perform a variety of resource related tasks including the evaluation/assessment of newly acquired MSHCP lands; one Park Ranger Supervisor, who oversees day-to-day field operations of Rangers and Park Maintenance Workers; three Park Rangers (level II), and three Park Maintenance Workers.

6.5. RCA Managed Properties

Currently, the Reserve Management Team oversees approximately 832 individual parcels (389 properties) totaling approximately 41,666 acres. Thirty properties were added to the RCA reserve inventory in 2019, equaling 1,481 acres (Table 6-1). The Park District only manages lands that the RCA holds either in fee title or in a conservation easement. Other lands are generally managed by their owning entities. The RCA continues to work with those owning entities to ensure reserve properties are managed in accordance with the MSHCP. Table 6-1. Properties Added to the Reserve Inventory in 2019.

6.6. 2019 Management Activities

6.6.1. Property Assessments

Properties that meet MSHCP conservation needs continue to be acquired by the RCA. Following appraisals and negotiations, the RCA requests a walk-over inspection of the site by the Reserve Management Unit to ensure there are no significant issues that would prevent the RCA from taking fee title and/or managing the property consistent with the MSHCP. Such issues include significant trash, hazardous materials, or other health and safety issues. Reserve Management also inspects the property to ensure that the property corners have been clearly staked and marked. If no issues are identified during the inspections, the RCA is informed, and the acquisition can be completed. Once the acquisition is finalized, Reserve Management assumes management of the property.

6.6.2. Habitat Protection and Site Security

A clearly stated goal of land management by the MSHCP is the protection of reserve lands from human activities that degrade or destroy habitat. Measures put in place to ensure the protection of the species and limit habitat degradation include fencing, gates, fuels reduction/weed

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 6-6

6.0 MANAGEMENT ACTIVITIES abatement, and increased ranger patrol during sensitive periods of species life cycles (e.g., Burrowing Owl [Athene cunicularia] breeding season or wildflower bloom season). During 2019, the majority of MSHCP Reserve Management efforts were spent on these endeavors. As reserve assembly nears completion more Reserve Management staff time will be spent on adaptive and biological management of the Reserve properties. Currently, most staff time still needs to be spent securing and protecting the properties from damage.

The types of uses permitted on MSHCP properties continue to be addressed on a case-by- case basis in discussions between the RCA and the Reserve Management staff. In general, pursuant to the requirements of the MSHCP, passive public use is allowed on existing trails, such as hiking, running, birdwatching, and mountain biking. Equestrian use is also allowed on RCA lands that supported such activity at the time of acquisition. Motorized access or recreation (e.g., off-highway vehicles [OHV]), hunting, shooting, archery (unless authorized by the RCA), trail creation, camping, and fires are not permitted.

Maintenance efforts continue to focus on the establishment and maintenance of access controls in areas with significant unauthorized use. Such areas during 2019 included the San Jacinto, Gavilan Hills, Badlands, and the Sage/Anza areas. In total, Reserve Management staff fabricated and installed approximately 1.89 miles of new fencing at 12 different sites and fabricated and installed eight gates and two equestrian access step-overs in 2019. As in previous years, enforcement during 2019 focused on the patrol for the interdiction of OHV users, illegal dumping, and homeless encampments. However, 2019 also presented unique challenges to the MSHCP Reserve Management Unit. Substantial resources and staff time were also devoted to patrols and closures of trails illegally created by users (e.g., mountain bikers), wildflower super-bloom patrols, and the interdiction of illegal marijuana grows on RCA reserve land (Figure 6-4).

The effectiveness of interdiction and cooperation from OHV users continues to be difficult and problematic (Figure 6-5). While establishing and maintaining OHV access controls and regular patrols, Reserve Management staff continued to work with external entities for assistance. Coordination continued with Park District Rangers (Open-Space Unit), the Riverside County Sheriff’s Department, local law enforcement agencies, and U.S. Bureau of Land Management (BLM) in an attempt to solicit assistance. Of particular interest was an increase in communication between the Riverside Sheriff’s Department Hemet Station and Reserve Management staff. In 2019, the Hemet Station showed renewed interest in the issues of illegal OHV activity in the south-eastern (Hemet, San Jacinto, Sage/Anza) section of the Plan area. Areas of OHV activity, impacted species, and a letter of support was provided to the Station to bolster their attempts to obtain an OHV grant for the purpose of establishing a ROVE (Riverside County Off-Highway Vehicle Enforcement) program.

6.0 MANAGEMENT ACTIVITIES

Illegal dumping continues to be a major concern and usurps many management resources, including time and equipment. Dumping includes refuse associated with homeless encampments, roadside litter, stolen vehicles, landscaping, household trash, and marijuana grow sites. Although the amount of refuse removed from RCA lands decreased considerably from 2018, 17.17 tons (34,340 pounds), a decrease of 25.25 tons from 2018, was removed from RCA properties in 2019 and transferred to county waste facilities. In addition to refuse brought directly to county landfills, roughly 52 yards of additional refuse was removed and placed in Parks District dumpsters, at the Natural Resources Management Offices at Hidden Valley Wildlife Area and the Goodhart Residence. On three separate occasions, not accounted for above, contact information found within piles of dumped household debris, was used to contact the offending party. On each of these occasions, the offending party was persuaded to return to the dump site and remove the dumped belongings from RCA properties. Nine stolen vehicles were also removed from RCA conserved lands in 2019, after being discovered by MSHCP Reserve Management staff.

Homeless encampments continue to be an issue on RCA conserved lands. These encampments are usually located in sensitive riparian habitat due to the natural cover that is provided. Negative impacts associated with these camps include massive amounts of trash, cleared vegetation, contaminated water, and increased risk of wildfire from cooking and campfires. In 2019, 15 active and abandoned homeless camps were located, cleared of their occupants, and/or cleaned of refuse by Reserve Management staff. These included five instances where individuals had appeared to have only spent one night on RCA properties. This number was an increase from 12 encampments cleared in 2018.

number of visitors flocked to the area to witness the bloom. Centered on the RCA Reynolds property, County-owned Long Beach Equities property, and adjacent private parcels, visitation was typically thousands of individuals per day, with peak crowds of tens of thousands of individuals per day. In conjunction with a large effort organized by the City of Lake Elsinore, nearly all of the Reserve Management Unit’s resources were required for February, March, and part of April to prevent the mass trampling of the blooming flowers. The nature of the event required several staff members to be onsite for all daylight hours, for the duration of the bloom. Staff time was predominantly focused on direct interactions with the public to keep them on the trails, but time was also committed on installing signage, temporary and permanent fencing, and answering questions from and providing assistance to members of the public.

Figure 6-7. Crowds on the Reynolds Property During the Super Bloom in Lake Elsinore.

Of increased concern to MSHCP reserve lands in recent years is the increase of recreation on the landscape, particularly of mountain bike use. The southwestern portion of the Plan Area has seen rapid growth in this recreational activity, with dozens of miles of unauthorized trails constructed on private property, Public-Quasi Public lands, and RCA reserve land in the area. Geographical areas such as the Murrieta Hills, Oak Mountain, Warm Springs Creek, and the Temecula Escarpment have been the hardest hit areas. In 2019, the Reserve Management Unit increased its effort to directly address the issue. Utilizing a newly acquired e-bike, trail patrols were increased to approximately a weekly basis in 2019. Time was spent during these patrols identifying and closing illegally created trails, reinforcing and expanding vandalized or ignored closed trails, making contacts with users, and generally becoming familiar with trail systems, and showing a presence on the landscape. Despite these efforts, vandalism to the access controls (e.g., signs, temporary fencing, brush piles, etc.) for the closed trails remained problematic throughout the year. To resolve this issue it will require creative solutions as well as ample amounts of time and resources in the future. A reserve-wide plan of public outreach, trail closures, restoration, and an increase in ranger patrols and enforcement will be considered in 2020 to combat this growing

threat.

Figure 6-8. Staff clearing the Sheffield property of marijuana grow site debris and closing an illegally created trail at the Gentry property.

With the decriminalizing of marijuana in the State of California, land managers have witnessed an uptick of illegal marijuana grows occurring on public lands. Conserved lands in western Riverside County have not been immune to this increase in illegal grows, and the Reserve Management Unit addressed two moderate sized grows in 2019. At the RCA Sheffield property, staff coordinated with the South Western Riverside Sherriff’s Station Marijuana Task Force to clear a two-acre marijuana plot. Following the removal of approximately 2,000 mature plants by the Task Force, staff entered the property and removed all the debris associated with the grow site. In total, 27.8 yards of irrigation tubing, fencing, wooden stakes, litter, and a large water tank were removed from the property and disposed of. The cleared areas were expected to passively recover from the incursion, as most cut shrubs were observed resprouting from their root crowns during the clean-up. Staff also conducted reconnaissance of a marijuana grow site in the riparian area of the County-owned White Rocks property and coordinated with the Lake Elsinore Riverside Sherriff’s Station Marijuana Task Force for its removal. The Task Force successfully removed approximately 2,000 young plants and a bottle of the highly toxic and banned insecticide, Carbofuran from the site.

Management Activity Data Sheets (MADS)

In 2019, Management staff continued to document remedial actions taken on lands impacted by disturbance or unauthorized activity. Mapped results depict known hotspots and allow Ranger and Maintenance staff to respond accordingly. Reserve Management staff submitted 277 MADS in 2019. The following incidents were documented and corrected: 21 major dumping issues (compared to seven in 2018), four target shooting contacts (same as in 2018), 40 incidents of damage to fencing (same as in 2018), 17 incidents of gate damage (compared to four in 2018), 24

6.0 MANAGEMENT ACTIVITIES

OHV contacts (compared to nine in 2018), and 24 incidents of mountain bike damage (new category created in 2019). In total, 1755 feet of fencing was repaired or replaced due to theft or damage, compared to 895 feet repaired in 2018.

Of the 277 MADS recorded, 143 were associated with OHV activity. OHV activity is costly to RCA lands because the activity damages habitats, fencing, gates, and provides a level of human presence that dissuades wildlife use. Gates and fencing are destroyed for ingress and egress and creation of new trails and/or jumps occurs. Direct-contact and escort removal of OHV users occurs regularly, however, RCA Rangers are not always able to make direct contact, either because the OHV user flees the area, or because the use occurs when RCA Rangers are not present.

6.6.3 Management Coordination

During 2019, the monthly Reserve Managers meetings continued to provide a venue to discuss coordination between non-RCA and RCA land management entities within the boundaries of the MSHCP Plan area. Since the inception of the Reserve Managers group, the meetings have grown to include members from most local management agencies, including the USFWS, U.S. Forest Service, BLM, CDFW, California Department of Forestry and Fire Protection, California Department of Parks and Recreation, the Center for Natural Lands Management, and other non- profit entities. Together, this group discusses a myriad of management and monitoring issues and how to best solve them.

MSHCP Reserve Management staff also attends monthly meetings with the RCA and the MSHCP Biological Monitoring Program management to discuss monthly activities, seek input on management issues, and generally coordinate field evaluations for RCA acquisitions. Additionally, Reserve Management staff meets internally on a monthly basis to discuss current projects, new acquisitions, and to coordinate management activities.

Various interagency working groups focusing on single species were attended by Reserve Management staff. These working groups brought together individuals and organizations specializing on or managing key sensitive species. The working group system provides a collaborative platform which facilitates problem solving and management decision making for a particular species. In 2019, these working groups included; Western Riverside County Burrowing Owl (Athene cunicularia) working group, Santa Ana-Palomar Mountain Lion (Puma concolor) linkage working group, Delhi Sands Flower-loving Fly (Rhaphiomidas terminatus abdominalis; Delhi Fly) working group, San Bernardino Kangaroo Rat (Dipodomys merriami parvus) working group, Brand’s Phacelia (Phacelia stellaris) working group, and Tamarisk Beetle (Diorhabda carinulata) working group.

Several symposiums and conferences were attended by Reserve Management staff. Professional conferences allow for dissemination of and collaboration on the newest science and developments within their respective areas. In 2019 staff attended the Western Section of the Wildlife Society Conference, Southern California Botanists Symposium, California Invasive Plant Council Symposium, the Santa Ana River Symposium, Park Rangers Association of California Conference, and a World Agriculture Expo.

6.6.4 Habitat Enhancement

In 2019, Reserve Management continued efforts to enhance disturbed habitat at RCA properties. Activities conducted during 2019 included new active restoration projects, as well as management of existing restoration projects that will directly benefit the MSHCP’s Covered Species. Some of the highlighted projects are described below.

Burrowing Owl Translocations

MSHCP Reserve Management staff continued work associated with the Burrowing Owl translocation, which occurred on the Nuevo Donation property in 2018. With help from a Mount San Jacinto College intern, the property’s remaining pair of Burrowing Owls was monitored. The pair of owls laid eight eggs in one of the property’s artificial burrows. Unfortunately, the nest failed prior to hatching when one of the adult owls was depredated (preyed on). Nevertheless, habitat management of the former farm field continued. On two separate occasions in spring, the 87.4-acre parcel was tractor mowed by Reserve Management staff, and the area around each of the property’s artificial burrows were string trimmed. The mowing and string trimming were necessary to maintain suitable foraging habitat for the property’s owls. A secondary goal of the mowing was to reduce the nonnative seed bank on the property, by timing the mowing prior to seed development. In order to provide additional foraging habitat, staff coordinated with the adjacent San Jacinto Wildlife Area to have 100 acres of their fields mowed by a Parks District contractor. Finally, staff organized and coordinated the native seeding of the property late in the year. Prior to the seeding, staff drug the entire property with a tractor-drawn blade to remove as many nonnative seedlings as possible. A large tractor-drawn soil imprinter was then used to disperse 1,600 pounds of site-appropriate native seeds across the property. The Lewis Group of Companies, whose development project necessitated the original translocation of the burrowing owls in 2018, provided the funds for both the seed purchase and the soil imprinting contractor. By years end, the property had an assortment of native and nonnative vegetation sprouted across the site, and the property’s artificial burrows were occupied by up to three owls.

6.0 MANAGEMENT ACTIVITIES

6.7.1 BFW CORONA1

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management The BFW Corona property was patrolled periodically during 2019. A large storm event early in the year, resulted in an abnormally high flow of Temescal Creek across the property. The high water transported large amounts of woody debris and ashy silt across the property due to sediment transport from above where the Holy Fire scared the lands.

Dense gum trees (Eucalyptus spp.) on the riparian dominated property make the site suitable for potential future mitigation/restoration action.

6.7.2 DR Horton2

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management Other than occasional perimeter patrols, no management was done on the DR Horton property in 2019. Due to the double wrought iron fences along its border with the adjacent housing development, the property has very little access by the public. The coastal sage scrub and riparian restoration areas on the property continue to show signs of success, as measured by high survivorship of the planted shrubs and trees. Approximately 1,000 feet of PCV pipe and sprinkler heads still remain on site and could be removed. Management of the property is conducted by Elsinore/Anza/Murrieta Resource Conservation District (under contract to the County Roads HOA).

6.7.3 Elsinore Lakeview Estates and Elsinore Lakeview Estates #2 Donation3

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management Management actions consisted of occasional patrols by MSHCP Reserve Management Rangers at the two properties. While OHV activity on the property has had a marked decrease since its acquisition, the properties continue to be accessible to and moderately used by OHV riders. OHV activity mostly occurs on portions of a former track in the central valley portion of the Elsinore Lakeview Estates #2 property, but also occurs on the main ridges of the Elsinore Lakeview Estates property. Increased patrols of the area by MSHCP Rangers and the Sheriff department is warranted and recommended to discourage OHV activity at the site. The rugged topography and general openness of habitat on the property makes physical access control measures, such as fencing infeasible. Installation of a gate at a choke point, off the property to the southwest may decrease some OHV activity but is currently beyond the purview of the Reserve Management Unit and RCA. Additional acquisitions in the area will potentially provide for a more defensible reserve boundary in the area. Measures to address moderate erosion from the OHV activity in the central valley portion of the #2 Donation could be implemented.

6.7.4 Emerald Meadows4

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management In 2019, management activities on the Emerald Meadows property included periodic patrols as well as annual weed abatement. Weed abatement of the property included string trimming the property’s boundary along Riverview Drive, and around an adjacent private property structure. Internal strips of the property were also tractor mowed, including an upland strip, mowed along the riparian area which passes through the edge of the property. Late in the year however, the entire property burned during the 46 Fire. On the Emerald Meadows property, fire severity ranged from high in the upland areas to moderate in the riparian area. Prior to the fire, the upland habitat was

6.0 MANAGEMENT ACTIVITIES dominated by various nonnative annual weeds. A change in composition of the upland habitat is expected on the property post-fire and may include more native coverage. The moderate severity of the fire in the riparian area left most of the native trees intact. Because of this, adverse long- term impacts of the fire to the riparian habitat are expected to be limited. Two short sections of fencing which were damaged during fire suppression activities were repaired.

6.7.5 EMWD SJ River Conservation Easement5

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management Several factors continued to make OHVs a key problem for the property in 2019; the property is composed of several disjunct parcels within the historically high OHV use area of the San Jacinto River wash. The property’s parcels are surrounded and separated by an assortment of land owners which are beyond the purview of the MSHCP Reserve Management Unit, and robust OHV access controls are difficult to impossible to achieve within the channel of the San Jacinto River. In order to limit damage from OHVs to the property, Reserve Management Rangers patrol the property on a weekly basis. Contacts and attempted contacts with OHV riders in the area were a routine occurrence for Ranger staff. Of equal regularity, was the repair of cut fencing. Several newly identified OHV access points from neighboring private properties were also blocked by staff in 2019. Discussions were held with the Environmental Manger of the neighboring Soboba Band of Luiseno Indians, to solicit their cooperation with installing OHV access control within Tribal Lands, that would further reduce OHV access points into the wash. While the initial response to the request was promising, no decisions to increase OHV access controls on Tribal Land was made by the Tribe in 2019.

Occasional homeless encampments on the property continued to be addressed. In 2019, two new small homeless camps and one abandoned homeless camp were located and cleared of occupants and refuse. In total, approximately 6.9 yards of homeless refuse were removed from the property.

In addition to enforcement activity, staff continued San Bernardino Kangaroo Rat (Dipodomys merriami parvus) vegetation management and monitoring on the property. In two separate areas, identified as choke points limiting the dispersal of kangaroo rats, dense stands of Thickleaf Yerba Santa (Eriodictyon crassifolium) were treated for removal. In total, 2.46 tons of the shrub were cut

6.0 MANAGEMENT ACTIVITIES and removed from the two locations. The remaining stumps were treated with herbicide. Stands of invasive Stinknet (Oncosiphon pilulifer) were also hand pulled and removed from both areas, and one of the areas was string trimmed to reduce annual nonnative vegetation cover. Photo point monitoring stations across the property were visited on a quarterly basis.

6.7.6 La Laguna Donation6

Species Monitoring In 2019, the MSHCP Biological Monitoring Program conducted rare plant surveys on the property. Eight patches of Coulter’s Matilija Poppies (Romneya coulteri) were located within the property during the surveys. Late in the year the Monitoring Program also installed one set of herp arrays in the canyon bottom of the property. However, the herp arrays were not opened and checked in 2019. Nevertheless, Belding's Orange-throated Whiptail (Aspidoscelis hyperythrus beldingi), Coastal Western Whiptail (Aspidoscelis tigris stejnegeri), Northern Harrier (Circus hudsonius), and Sharp-shinned Hawk (Accipiter striatus) were incidentally observed on the property during survey efforts.

Management In 2019, management activities focused on issues caused by the 2018 Holy Fire. In the wake of the fire, the denuded hillsides of the La Laguna property, and neighboring Bishop property became attractive to a myriad of recreational users. In order to prevent the establishment of new trails in the area, and to block motorized vehicle access to both properties, Reserve Management staff installed 974 feet of fencing along the eastern boundary of the Bishop property. Staff also reviewed and commented on plans from Elsinore Valley Municipal Water District (EVMWD), to repair and regrade a water tank access road. The access road bisects the property and was washed out in several locations by storm water following the fire. During repairs to the road, staff conducted daily checks to assure that EVMWD was abiding by the terms of their Right of Entry with the RCA.

Large numbers of invasive Saltcedar (Tamarix ramosissima) seedlings recruited in the canyon bottom of the property during spring 2019 (i.e., the first spring after the 2018 Holy Fire). Staff hand- pulled approximately 1,000 Saltcedar individuals from the property, to prevent their establishment. Discussions were held with U.S. National Forest staff in an attempt to persuade them to remove additional Saltcedar trees on Forest Service Land upstream of the property, to decrease future infestations. The Forest Service was aware of the issue but acknowledged they were dealing with a myriad of issues related to the fire. The forest service was hopeful that they would be able to remove the Saltcedar in coming years. Staff also visited quarterly photo point monitoring stations across the property.

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys in 2019 at this property. However, one White-tailed kite (Elanus leucurus) was incidentally observed perched on a snag on the property by MSHCP staff.

Management The property was patrolled periodically during 2019 with no issues to report.

6.7.8 RCTC Conservation Easement8

Species Monitoring The MSHCP Biological Monitoring Program conducted Mountain Plover surveys on the Riverside County Transportation Commission (RCTC) Conservation Easement in 2019. While no Mountain Plovers were documented, the surveys did document Loggerhead Shrike (Lanius ludovicianus), Sharp-shinned Hawk, and White-tailed Kite utilizing the property.

Management The property was patrolled periodically during 2019 with no issues to report. The site is still being managed by RCTC to fulfill mitigation requirements that include restoration of vernal pools and establishment of narrow endemic plants.

6.7.9 Richmond American9

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management The Richmond American property was a conservation easement originally recorded in 2003 in favor of The Environmental Trust but came to the RCA in 2007. Management activities include periodic patrols and weed abatement using string trimming adjacent to housing, along the western boundary of the property.

6.7.12 TET Sedco Hills12

Species Monitoring The MSHCP Biological Monitoring Program did not perform focused surveys on the property in 2019.

Management In 2019, management activities on the TET Sedco Hills property included regular patrols to deter OHV activity. The adjacent Nelson property was purchased in 2015 and continues to be patrolled to prevent OHV access, which in turn helps protect the TET Sedco Hills property. Several cuts to the Nelson property’s eastern fence line were located and repaired by staff. These access controls have been moderately successful at reducing OHV activity on the TET Sedco Hills property, as many of the property’s former OHV trails have become inactive and have begun to grow over with vegetation. Additional OHV access controls in remote areas, abutting private property, should be considered to further reduce the activity on the property.

6.0 MANAGEMENT ACTIVITIES

Several abandoned cars and old household refuse remain in place at the old house site, in the southern portion of the property. Inaccessibility to the former house site makes cleanup difficult to impossible, and efforts to approach a neighboring private landowner for access have been unsuccessful. Ultimately, a washed out and overgrown dirt road on the property will need to be graded to allow access so that the items can be removed.

6.7.13 Teledyne13

Species Monitoring The Biological Monitoring Program conducted Delhi Fly Line-Distance Transect surveys at the property in 2019. The purpose of these surveys was to document presence and reproduction of the federally endangered fly at the site. Currently, the only population of Delhi Fly on conserved lands within the MSHCP area occurs at Teledyne. The 2019, surveys documented both presence and reproduction of Delhi Fly at the site. The overall numbers of Delhi Fly observations, as well as population estimates increased substantial from the 2018 numbers and are now back to numbers like that prior to 2018.

In 2019 the MSHCP Biological Monitoring Program conducted rare plant surveys on the property, which documented the presence of hundreds of Plummer's Mariposa lily (Calochortus plummerae).

During protocol surveys several incidental MSHCP Covered Species were also documented using the property. These included Coastal Western Whiptail (Aspidoscelis tigris stejnegeri), Granite Spiny Lizard (Sceloporus orcutti), Northern Red-diamond Rattlesnake (Crotalus ruber), Coastal California Gnatcatcher (Polioptila californica californica), Cooper's Hawk, Turkey Vulture (Cathartes aura), and Coyote (Canis latrans).

Management MSHCP Reserve Management staff continued the Delhi Fly restoration and habitat improvement project at the property. Work completed on the site in 2019 included (1) maintenance with a quad and harrow on the ±2.5 miles of paths created in previous years in order to provide open non- vegetated areas, (2) hand weeding of 8.32 acres to remove non-native forbs (mainly Short- pod Mustard, Saharan Mustard, and Golden Crownbeard) prior to their seeding, (3) bi-monthly visits to the property’s 10 photo point monitoring stations, and (4) dispersing native seeds at the site. The native seeds were collected for the property throughout the year by a Mount San Jacinto intern, and included approximately 40 species of native plants, that historically occupied the Fly’s habitat but have disappeared from the Teledyne property.

6.7.14 Toscana Donation Phase 114

Species Monitoring The MSHCP Biological Monitoring Program conducted riparian bird surveys, riparian bird nest monitoring, and rare plant surveys on the property in 2019. Rare plant surveys of the property revealed three small stands of Coulter’s Matilija Poppy. During the riparian bird surveys Least Bell’s Vireo (Vireo bellii pusillus), Yellow Warbler (Setophaga petechia), and Yellow-breasted Chat (Icteria virens) were documented utilizing the property. Through the efforts of these surveys and the riparian bird nest monitoring (which focused on Yellow Warbler and Yellow-breasted Chat only) one successful Yellow Warbler nest, one successful Yellow-breasted Chat nest, and one failed Yellow-breasted Chat nest were documented. A Downey Woodpecker (Picoides pubescens) adult and fledgling were also observed incidentally on the property.

Additional MSHCP Covered Species incidentally documented during survey efforts on the property in 2019 included Cooper's Hawk, Southern California Rufous-crowned Sparrow (Aimophila ruficeps canescens), and Wilson's Warbler (Cardellina pusilla).

Management 2019 management activities on the site were limited to periodic patrols. The property is adjacent to, and within the Terramor housing development. Construction of this development was ongoing throughout 2019. The site is being managed by the Terramor developers (Foremost Companies), to fulfill mitigation requirements that include fencing large portions of the property, actively restoring or enhancing ±63 acres of riparian and alluvial fan sage scrub, and installing a MSHCP-covered trail through the property. Through fencing and strategic native landscaping, access by the public has been effectively restricted to permitted access points. The areas of ongoing restoration continued to show good increases in biomass of native species. Three gates, which access the restoration areas were found to be routinely unlocked. Staff coordinated with the Riverside County Economic Development Agency to assure the gates remained locked with all stakeholders’ locks in place.

• Continue to plan and implement vegetation control measures, including the use of prescriptive burns, herbicide, grazing, and mechanical means to protect particularly sensitive habitats and species. • Perform public outreach with the mountain bike community to raise awareness, garner support, and acquire volunteers to assist with addressing illegally created trails on RCA Reserve Lands. • Maintain patrol and maintenance efforts. • Purchase and install fencing and other access controls, such as k-rails or boulder fences. • Perform necessary infrastructure improvements on existing properties to reduce erosion, access, etc. • Continue to actively manage habitat at Burrowing Owl translocation sites. • Continue and increase cooperation and coordination with local law enforcement entities.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 6-23 7.0 MONITORING ACTIVITIES

7.0 MONITORING ACTIVITIES

7.1 Goals and Objectives

The overall goals of the Biological Monitoring Program (Monitoring Program) are to collect data on the 146 Covered Species and associated vegetation communities over the 500,000-acre Conservation Area to assess the MSHCP’s effectiveness at meeting conservation objectives and to provide useful information to Reserve Managers in an adaptive management context. The MSHCP (Volume 2, Species Accounts) includes species-specific objectives that are intended to provide for the long-term conservation of all Covered Species. Species objectives direct the type and intensity of monitoring that is conducted by the Monitoring Program on an annual basis. Management decisions or actions are triggered if species objectives or MSHCP conservation goals are not met.

7.2 Inventory Phase and Long-term Monitoring Phase

Because there was little existing science-based data for the majority of Covered Species when the MSHCP was permitted, the Monitoring Program is being implemented in two phases: an initial Inventory and Assessment Phase (Inventory Phase) and a Long-term Monitoring Phase. The purpose of the Inventory Phase was to determine where Covered Species occur within the Conservation Area, to gather more information on their habitat preferences and life history (e.g., seasonal activity, reproduction requirements), and to develop efficient survey protocols for species detection. The development of science-based survey protocols is necessary to standardize data collection, to test the reliability of survey methods, to determine feasible and useful monitoring metrics, and to provide a confidence level that unobserved species are truly absent at the survey location, rather than overlooked.

The transition from Inventory Phase to Long-term Monitoring Phase has been gradual rather than abrupt. For species with short reporting requirements such as Quino checkerspot butterfly (annual) or coastal California gnatcatcher (every three years) Long-term monitoring is already in place. Multiple surveys for species with short reporting requirements have been conducted, providing the initial data points for population trend assessment. For species with longer reporting requirements such as Los Angeles pocket mouse (every eight years) and with species-specific monitoring objectives requiring significant development and testing, the transition from Inventory Phase to Long-term Monitoring Phase is ongoing.

The transition into long-term monitoring involves developing monitoring metrics that are both efficient to collect, and robust measures of species status and population trend. The baseline monitoring objective for most Covered Species requires at least 75% of listed Core Areas or known locations to be documented as occupied at least once every eight years. Monitoring protocols that

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-1 7.0 MONITORING ACTIVITIES

provide additional information such as relative abundance of populations at occupied locations, reproductive success, or health of observed individuals will be employed whenever possible, to provide the most useful representations of species status. Monitoring Program staff have worked in collaboration with University of California Riverside Center for Conservation Biology staff to develop conceptual models of Covered Species and their habitats to help identify key population drivers and environmental stressors upon which management can act.

One significant task included in the Inventory Phase was development of a Long-term Monitoring Strategy document, as described in Section 5 of the MSHCP (Volume 1). This document explicitly describes the approach taken to meet the goals of the Monitoring Program. It does not include taxa-specific monitoring protocols, which are available from the Monitoring Program by request. Monitoring Program staff completed and delivered the Long-term Monitoring Strategy to the RCA and the California Department of Fish and Wildlife (CDFW, previously Department of Fish and Game) as part of a State Wildlife Grant that expired on June 30, 2012.

The Long-term Monitoring Strategy describes a two-level design that gives priority to assessing the status of Covered Species as stated in the species-specific conservation objectives of the Plan which emphasize the continued occupancy of MSHCP-defined Core Areas or other areas of known occurrence. For some species, the objectives require that reproduction and/or minimum densities of individuals within species Core Areas be verified. The second level extends sampling for terrestrial vertebrates to the entire Conservation Area in a cost-efficient manner. The Long-term Monitoring Strategy document also includes chapters describing monitoring goals and objectives, sample design considerations, proper protocol development, data and information management strategies, collaboration, and communication with other organizations, and describes the organizational framework of the Monitoring Program.

One of the explicit goals of the Monitoring Program is to develop efficient long-term monitoring protocols that reduce redundancies by collecting information on multiple species where possible. For example, bird species co-occurring in similar habitat (e.g., willow riparian) during the breeding season can be detected using the same survey protocols. There will always be some Covered Species that occur in isolated pockets within the Conservation Area or that are difficult to detect using standard survey protocols; for these species, a focused survey effort will always be required.

7.3 Monitoring Program Operations

The Monitoring Program is implemented within the MSHCP Conservation Area on lands that are owned and managed by the various MSHCP participants and other entities and is comprised of both PQP (347,000 acres) and ARL (61,815 acres). CDFW was responsible for implementing the Monitoring Program for the first eight years of the Permit (MSHCP Volume 1, Section 6). To ensure consistency in monitoring efforts throughout the Conservation Area, the Monitoring

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-2 7.0 MONITORING ACTIVITIES

Program is overseen and implemented by a Monitoring Program Administrator. Effective July 1, 2012 when the State Wildlife Grant ended, the RCA assumed all funding responsibility for the Monitoring Program with the exception of one full time position serving as the Avian Lead.

In the initial years of the Monitoring Program, extensive effort was devoted to setting up operating procedures, determining budgets, establishing contracts, purchasing supplies and equipment, hiring and training personnel, acquiring land access agreements, and coordinating with Reserve Managers within the Plan Area. These processes are now largely developed and only require updating (e.g., operating procedures), renewal (e.g., expiring right of entry agreements), or training when new personnel are involved (e.g., new Monitoring Program staff or Reserve Managers).

An integrated database to make information collected by the Monitoring Program manageable and accessible is now complete. Monitoring Program datasets that have been thoroughly proofed and certified complete by the Data Manager are submitted to CDFW’s Biogeographic Information and Observation System every year, as well as to local partnering agencies and entities. The structure needed to support a long-term Monitoring Program is in place.

7.3.1 Monitoring Program Personnel The Biological Programs Manager oversees staff funded by the RCA and provided by CDFW. RCA-funded staff are provided through a contract with the Santa Ana Watershed Association (SAWA). Monitoring Program staff work together as a team to coordinate, develop, and implement required monitoring activities for the MSHCP.

At the beginning of 2019, 14 positions were filled in the Monitoring Program, 13 of which were funded by the RCA, with one funded by CDFW. Eight of these positions consisted of office-based staff and Taxa Leads and six full-time field biologists. On August 19, 2019 an additional field biologist was added to the crew to monitor the Clinton Keith Overcrossing project, bringing the total number to seven and the total number of staff to 15 (14 funded by RCA and one by CDFW). The Data Manager position became vacant and Karyn Drennen (Botany Lead) was chosen as the new MSHCP BMP Data Manager, effective September 23, 2019. The Botany Lead position was announced, interviews held, and a candidate was selected to begin in January 2020.

Annual staffing levels, and therefore survey effort, reflect the budget available to the Monitoring Program. Although progress continues to be made towards documenting the current status of all 146 Covered Species, the availability of funds will ultimately determine whether or not the species objectives can be evaluated within the time frame designated by the MSHCP.

7.3.2 Training All Monitoring Program field biologists are trained on local species identification, handling, and data collection methods. Field staff are cross trained in identification and survey techniques for multiple taxa to provide scheduling flexibility and increase staff efficiency. Specific training provided in any given year depends on the survey activities planned; however, safety training (e.g., wilderness first aid and CPR) is provided to all staff as necessary to keep certifications current. The Monitoring Program is required to use training programs approved by the Wildlife Agencies to ensure consistent data collection, uniform implementation of protocols, safe handling procedures, and appropriate experience with Covered Species (MSHCP Volume 1, Section 7). Training is provided both by experienced Monitoring Program biologists and by qualified outside entities (e.g., U.S. Geological Survey, U.S. Fish and Wildlife Service). More information on species training received is presented in Appendix C – Staff Training.

7.3.3 Land Access Agreements and Coordination with Reserve Managers The Monitoring Program only conducts surveys within the existing Conservation Area, which is composed of PQP lands and AR (Additional Reserve) Lands. Before surveys are conducted by the Monitoring Program, permission is obtained from the appropriate landowners or managing entities to access the survey areas. Land access agreements for 2019 for Monitoring Program activities are listed in Appendix B, Table B-1. Access Agreements for 2019 Surveys.

To facilitate land access and to better coordinate monitoring activities with management activities, Monitoring Program staff meets monthly with Reserve Managers (Reserve examples listed in Appendix B, Table B-1). At these meetings, Monitoring Program staff provide a description of current activities, including protocols and maps when relevant, and present species occurrence data and current monitoring results to the Reserve Managers. Management/Monitoring coordination meetings also feature a short presentation on a relevant topic. Speakers range from researchers at local universities, local biologists conducting similar monitoring or land management work, regulatory officials, as well as MSHCP staff presenting monitoring results. In 2019, meeting topics included:

• Santa Ana Sucker

• 2018 Management Program Activity Highlights

• Upper Santa Ana River Habitat Conservation Plan

7.4 Summary of 2019 Monitoring Activities and Evaluation of Progress toward Achieving Measurable Objectives

The activities of the Monitoring Program are largely based on requirements of the MSHCP species-specific monitoring objectives outlined in Section 5 of the MSHCP (Volume I). Species objectives specify time intervals for detecting and reporting on each of the Covered Species in the Conservation Area. When species objectives do not specify a time interval, the status of the Covered Species must be reported at least once every eight years. In addition to species objectives, survey priorities are influenced by the quantity and quality of information available for each species (e.g., little or poor information means greater survey effort more frequently), whether another agency is already conducting surveys (less effort required by the Monitoring Program), relative ease of gathering information (e.g., Yellow Warbler detections during Least Bell’s Vireo surveys), and priority of the species to the RCA, Permittees, and Wildlife Agencies (e.g., Burrowing Owl is high priority).

The Monitoring Program only addresses species objectives that must be evaluated using biological surveys. Those species objectives, along with the frequency of the reporting requirement, whether the species was detected in the past or in the current reporting year, and whether or not the stated objectives are met are provided in Appendix B, Table B-2. Details of Covered Species Monitoring. The majority (121 of 146) of the Covered Species must be reported on at least once every eight years. The remaining 25 species have reporting requirements that vary between one and five years. The Monitoring Program has developed a timeline for the survey of Covered Species. The scheduling of surveys is approximate due to the prioritization process described above and because survey protocols can take more than one year to complete. Modifications to the timeline are expected to occur based on the results of each year’s monitoring efforts and available budget.

The 2019 reporting period represents the fifteenth full survey season for the Monitoring Program. The following survey activities were carried out in 2019 by the Monitoring Program: • Burrowing Owl Monitoring

• Grasshopper Sparrows Survey and Habitat Assessment

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-5 7.0 MONITORING ACTIVITIES

• Yellow Warbler and Yellow-Breasted Chat Surveys

• Clinton Keith Wildlife Cameras

• Long-Tailed Weasel Survey

• Quino Checkerspot Butterfly Survey

• Delhi Sands Flower-loving Fly Survey

• Arroyo Chub Survey

• Vernal Pool Survey

• Rare Plant Survey

• Brand’s Phacelia Habitat Enhancement

• Incidental Species Sightings

Detailed survey reports for most projects, including the rationale for survey protocols, a description of methods, targeted species, and survey results can be found in Appendix A. For ongoing survey efforts with no change in the status of relevant species-specific monitoring objectives, survey reports will be completed when there are significant results to convey or when the effort concludes.

Evaluation of MSHCP monitoring objectives for Covered Species occurs annually. In 2019, Monitoring Program biologists conducted focused surveys for 36 of the 146 Covered Species in the Conservation Area. The 36 targeted Covered Species were detected, and an additional 58 Covered Species were incidentally observed (Appendix B, Table B-2. Details of Covered Species Monitoring). Additionally, Mountain Yellow-legged Frog and Santa Ana Sucker were detected during focused surveys conducted by other organizations. In total, 94 of the 146 Covered Species were detected within the Conservation Area in 2019. These numbers are calculated based on a 30- meter (m) buffer around the Conservation Areas that is used in creating the Species Occurrence Dataset. Since June 2004, a total of 141 of the 146 Covered Species have been detected in the Conservation Area.

Species-specific monitoring objectives, described in the Species Accounts from Volume 2 of the MSHCP, are evaluated at the interval indicated in the “Freq.” column of Appendix B, Table B-2. Details of Covered Species Monitoring. Objectives that have been met previously are subject to expiration based on the date the observations were last documented relative to the required monitoring frequency. When data collected by the Monitoring Program are determined to be sufficient to meet the species-specific monitoring objectives a “YES” appears in the “Obj.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-6 7.0 MONITORING ACTIVITIES

Currently Met” column. When data collected by the Monitoring Program indicate that the expected conservation identified in the species accounts has not been achieved, a “NO” appears in the “Obj. Currently Met” column. When data collected by the Monitoring Program indicate that the expected conservation identified in the species accounts has only partially been achieved (e.g., one of two objectives), a “Partial” appears in the “Obj. Currently Met” column and additional information with regards to which objectives have been met is provided. The Monitoring Program has collected sufficient data to confirm that species-specific monitoring objectives for 62 Covered Species are currently met. Monitoring objectives have been partially met for 10 additional Covered Species (Appendix B, Table B-2).

According to Section 2.1.4 of the MSHCP (Volume I), 118 of the 146 Covered Species were considered to be adequately conserved at inception of the Plan. The remaining 28 Covered Species will be considered to be adequately conserved when certain conservation requirements are met as identified in the species-specific conservation objectives for those species. For 16 of the 28 species, particular species-specific conservation objectives, which are identified in Table 9-3 of the MSHCP (Volume I), must be satisfied to shift those particular species to the list of Covered Species Adequately Conserved. For the remaining 12 species, a Memorandum of Understanding must be executed with the Forest Service that addresses management for these species on Forest Service Land in order to shift these species to the list of Covered Species Adequately Conserved.

When data collected by the Monitoring Program are determined to be sufficient to meet the species-specific objectives described in Table 9-3 of the MSHCP (Volume I) a “YES” appears in the “Table 9-3 Requirement Met?” column of Appendix B, Table B-3. Status of Covered Species Not Adequately Conserved. When data collected by the Monitoring Program indicate that the expected conservation identified in Table 9-3 of the MSHCP (Volume I) has not been achieved a “NO” appears in the “Table 9-3 Requirement Met?” column. When data collected by the Monitoring Program indicate that the expected conservation identified in Table 9-3 has only partially been achieved (e.g., one of two objectives), a “Partial” appears in the “Table 9-3 Requirement Met?” column. The Monitoring Program has collected sufficient data to confirm that requirements listed in Table 9-3 of the MSHCP (Volume I) for nine Covered Species Not Adequately Conserved have currently been met (Appendix B, Table B-3).

7.4.1 Burrowing Owl Monitoring The species objectives for Burrowing Owl require the conservation of five Core Areas, plus interconnecting linkages, containing a breeding population of 120 owls with no fewer than five pairs in any one Core Area. Core Areas listed in the MSHCP include: Lake Skinner/Diamond Valley Lake, playa west of Hemet, San Jacinto Wildlife Area/Mystic Lake area (including Lake Perris), Lake Mathews, and along the Santa Ana River. Several land managers within the Conservation Area have installed artificial burrows and are managing vegetation to facilitate

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-7 7.0 MONITORING ACTIVITIES

Burrowing Owl use of Core Areas. Reserve Managers or Monitoring Program biologists check all artificial and previously-occupied natural burrows at least three times each year (April, August, and December) to determine whether they are being used by Burrowing Owls, if there is burrow maintenance needed to make them hospitable to owls, and whether nearby habitat needs to be modified or managed to further encourage use by Burrowing Owls.

During the 2019 breeding season, we monitored four owl pairs within the Lake Skinner/Diamond Valley Lake Core Area. Eight active burrows were monitored, three of which showed evidence of nesting (Figure 7-1. Burrowing Owl Burrows Monitored in the Lake Skinner/Diamond Valley Lake Core Area during 2019 Pair Count Surveys). At least four fledglings were produced at two of these burrows (i.e., two fledglings per breeding pair). We did not detect any breeding pair of owls within the San Jacinto Wildlife Area/ Mystic Lake Core Area in 2019.

7.4.2 Grasshopper Sparrow Survey and Habitat Assessment The MSHCP identifies two species objectives for Grasshopper Sparrows.

Objective 1 requires the conservation of at least 38,690 acres (15,657 hectares[ha]) of suitable valley and foothill grassland habitats. This objective has not yet been met and relies on the completion of the 500,000-acre Reserve.

Objective 2 requires that the species maintain occupancy in three designated large (i.e., ≥809 ha of grassland or grassland-dominated habitat) Core Areas and at least three (75%) of four designated smaller (≥202 ha of grassland or grassland-dominated habitat) Core Areas in at least one year out of any five consecutive-year period. The species account identifies 11 potential Core Areas, including Badlands, Box Springs, Kabian Park, Lake Mathews-Estelle Mountain, Lake Skinner/Diamond Valley Lake/Johnson Ranch, Mystic Lake/San Jacinto Wildlife Area (WA), Potrero, Prado Basin, Santa Rosa Plateau/Tenaja, Steele Peak, and Sycamore Canyon. The Badlands and Potrero are both part of the Plan Area’s Core 3, so they were combined into a single Core Area for the purposes of this study. Five Core Areas (Badlands/Potrero, Lake Mathews- Estelle Mountain, Lake Skinner/Diamond Valley Lake/Johnson Ranch, Mystic Lake/San Jacinto WA, and Santa Rosa Plateau/Tenaja) currently contain at least 809 ha of grassland habitat and are thus considered large. Four additional Core Areas (Box Springs, Kabian Park, Steele Peak, and Sycamore Canyon.) contain at least 202 ha, but less than 809 ha, of grassland habitat. One Core Area, Prado Basin, contains just 142 ha of grassland or grassland-dominated habitat, so does not technically qualify as a small Core Area; however, we surveyed habitat in this Core Area for Grasshopper Sparrows in 2019. Finally, Objective 2 also requires that five of seven designated Core Areas support at least 20 Grasshopper Sparrow pairs with evidence of successful reproduction within the first five years after permit issuance (2004–2009). This five-year period has already passed, and the objective was not met when our program conducted Grasshopper Sparrow surveys in 2005, but we incorporated a nest searching and monitoring component in our 2019 surveys.

Detections of Grasshopper Sparrows

We detected Grasshopper Sparrows in three large Core Areas in 2019, and all five large Core Areas within the current reporting period (2015–2019), thereby meeting the first requirement of Objective 2 for the species (Table 7-1). We did not detect Grasshopper Sparrows within any of the small Core Areas in 2019, nor have we detected them in any of the small Core Areas during the current reporting period (2015–2019; Table 7-1 and Figure 7-2), thereby failing to meet the second requirement of Objective 2 for the species.

We have detected Grasshopper Sparrows 738 times on Conserved Land within the Plan Area from 2005 to 2019. Our detections are usually clustered within the Lake Mathews-Estelle Mountain (n = 103 detections), Lake Skinner/Diamond Valley Lake/Johnson Ranch (n = 251), and Santa Rosa Plateau/Tenaja (n = 320) Core Areas. We have a cluster of 12 detections at Oak Mountain, north of Vail Lake, but we have failed to detect the species here since 2017.

Detection Rates and Detection Probability Analysis

We conducted three survey rounds in this study. The percentage of surveyed transects along which we detected Grasshopper Sparrows increased from 22% in Round 1 to 39% in Round 2, then decreased slightly to 34% in Round 3. We detected Grasshopper Sparrows along 30 (43%) of our transects in 2019, and most (n = 17 transects, or 57%) of these were in the Santa Rosa Plateau/Tenaja Core Area, followed by the Lake Skinner/Diamond Valley Lake/Johnson Ranch Core Area (n = 10, or 33%).

Grasshopper Sparrow Nesting

We documented evidence of successful nesting by Grasshopper Sparrows within three large Core Areas in 2019 (Table 7-2, Figure 7-2), with three Grasshopper Sparrow nests detected in 2019; all ultimately failing. Two of the nests were in the Santa Rosa Plateau/Tenaja Core Area and one was in the Lake Mathews-Estelle Mountain Core Area (Figure 7-3). At least 18 fledglings in 10 separate locations across three Core Areas were detected (Table 7-2).

a Minimum number of fledglings seen.

The first nest we found was in the incubation stage on 2 May and contained five eggs, indicating that egg-laying was initiated in late April. The last active nest we found contained three eggs and two nestlings on 20 June. We first detected fledglings on 6 May and the latest fledglings were found by our biologists on 6 June.

The third part of Objective 2 for the species, which requires that five Core Areas support successful reproduction by the species was not met. Further, at least 20 Grasshopper Sparrow pairs must be successfully reproducing within each of the five Core Areas, which were not document in 2019.

Habitat Assessment

To determine whether there were measurable differences in 2019 between what was used by Grasshopper Sparrow versus other lands that appear to be suitable for the species but not used in 2019.

There were not any significant differences with respect to the variables we measured between the 68 locations used by the species and 68 randomly selected locations that appeared to have suitable habitat for Grasshopper Sparrow. Sites were most often northeast- or south-facing, although there was not an overall trend toward any one direction (Figure 7-4). Points were on gentle slopes and generally contained few trees within 50 m. Maximum vegetation height at used

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-12 7.0 MONITORING ACTIVITIES sites was an average of 38.8 cm and residual litter/thatch depth averaged 3.0 cm. Ground cover within 5 m of used sites was most often grass, followed by forbs (Table 7-3).

7.4.3 Yellow Warbler and Yellow-breasted Chat (Riparian Bird) Surveys The species objectives for Yellow Warbler and Yellow-breasted Chat require the demonstration of both use and successful reproduction within 75% of specified Core Areas every five years. Surveys were last completed in 2014. Thus, these two species were the targets of our 2019 riparian bird surveys, but we also collected data on all covered riparian bird species observed.

Detections of Target Species

We detected Yellow Warblers and Yellow-breasted Chats in 89% and 80% of their Core Areas, respectively, during the current reporting period of 2015–2019, thereby meeting the use area objective for both species (Table 7-4). Overall, we detected 93 avian species during our 2019 surveys, including 18 species covered by the MSHCP.

Yellow Warbler

We detected Yellow Warblers in 89% of their designated Core Areas during the current reporting period (2015–2019), with nearly all Core Area detections occurring most recently during our 2019 survey effort (Table 7-4). We detected Yellow Warblers on currently conserved land in the Murrieta Creek Core Area just once, in 2015 (Figure 7-5). We have never detected the species in the Vail Lake Core Area because our Program has never been granted permission to conduct surveys on conserved land there. The closest Yellow Warbler detection to the Vail Lake Core Area by our Program biologists occurred 670 m south of the Core Area, along Arroyo Seco (Figure 7- 5).

We have historically detected Yellow Warblers on several occasions within the following locations, any of which should be considered as alternative or additional Core Areas for the species: Lake Mathews/Estelle Mountain (Existing Core C; n = 21 detections from 2006–2019), Lake Perris/Mystic Lake (Existing Core H; n = 85 detections from 2005–2019), and Lake Skinner/Diamond Valley Lake (Existing Core J; n = 81 detections from 2005–2017) (Figure 7-5).

Yellow-breasted Chat

We detected Yellow-breasted Chats in 80% of their designated Core Areas during the current reporting period (2015–2019), with all Core Area detections occurring most recently during our 2019 survey effort (Table 7-4). As previously referenced, we have never detected the species in the Vail Lake Core Area because our Program has never been granted permission to conduct surveys on conserved land there.

We have historically detected Yellow-breasted Chats within the following two locations, either of which should be considered as alternative or additional Core Areas for the species: Lake Mathews/Estelle Mountain (Existing Core C; n = 14 detections from 2006–2014) and Lake Skinner/Diamond Valley Lake (Existing Core J; n = 4 detections from 2007–2011) (Figure 7-6)

Nesting of Target Species

We documented successful reproduction by Yellow Warblers in 56% of their Core Areas, failing to meet their reproductive objective during the current reporting period (Table 7-5, Figure 7-7). We documented evidence of successful reproduction by Yellow-breasted Chats in 80% of their Core Areas, meeting the reproductive objective for the species (Table 7-5, Figure 7-8). Successful Reproduction is defined as a nest which fledged at least one known young. This also includes young fledglings detected that are strongly dependent on their parents for food, weak fliers, and found well within the boundaries of the Conservation Area.

Yellow Warbler

We documented the production of Yellow Warbler fledglings in 3 (30%) of the 10 nesting attempts we observed (Table 7-6). Of the seven nesting attempts that failed, we attributed all to undetermined causes due to the height of the nests and our inability to inspect the contents following failure.

a Minimum number of fledglings seen; data include fledglings whose nests we did not locate.

Yellow Warbler nests found by our Program in 2019 were an average of 10.7 m above ground (range = 7–18 m) and substrates were an average of 15 m tall (range = 10–23 m). The three nesting substrates used by Yellow Warblers in 2019 were cottonwood (Populus spp.; n = 3 nests), California live oak (Quercus agrifolia; n = 1), and willow (Salix spp.; n = 6).

The earliest Yellow Warbler nest found in 2019 was in the construction stage on 16 April. We first observed nestlings on 15 May and fledglings on 21 May. The latest group of fledglings observed fledged sometime during the first 10 days of July.

Yellow-breasted Chat

One Yellow-breasted Chat nest was found in 2019, within the Temescal Canyon/Alberhill Creek Core Area (Figure 7-8). The nest was in the incubation stage when found on 14 June, containing three eggs. The nest was empty on 21 June, having failed sometime in the interim. The nest did not have structural damage, so we assumed depredation occurred, perhaps by an avian or snake predator. The nest was constructed in a tangle of Indian hemp (Apocynum cannabinum) and poison oak (Toxicodendron diversilobum) and was approximately 1.2 m above ground.

We found a minimum of seven chat fledglings distributed among the Prado Basin/Santa Ana River (n ≥ 2 fledglings), San Timoteo Creek (n ≥ 2), Temecula Creek (n ≥ 2), and Temescal

7.4.4 Clinton Keith Overcrossing and Undercrossing Monitoring Survey

This section provides baseline data from motion triggered cameras for the first six months of a planned five-year monitoring program at the Clinton Keith overcrossing and undercrossing.

In 2019, the Clinton Keith overcrossing and undercrossing was monitored using motion triggered cameras. Cameras were installed at the undercrossing on 2 July and on the overcrossing on 1 August. Upon entering the overcrossing on 1 July, we found excessive vegetation which prohibited the proper monitoring of the site by motion triggered cameras. Therefore, camera install was delayed while the vegetation was managed.

A total of four motion triggered camera stations were monitored at the over and undercrossings in 2019 (Figure 7-9. Clinton Keith Overcrossing and Undercrossing Camera Locations in 2019). Cameras were selectively installed to best capture use of the landscape by wildlife. Each camera was programmed to take a burst of 3 photos followed by a 1-minute delay. We found the 1-minute delay resulted in numerous blank photos, likely from wind, so the delay was increased to 5 minutes. Cameras were serviced (i.e., batteries checked, memory cards removed and replaced) every other week. After servicing, biologists reviewed the photos, choosing the best photo to represent what animal triggered the camera. Animals were identified to species where possible. However, some photographs did not allow for species identification and were either identified to genus or as unidentified. This work is not able to provide species abundance but does provide the species using the two different wildlife crossing features. In order to determine abundance, animals would need to be individually marked.

We determined the rate of occurrence for each species or grouping of species, by dividing the number of detections per species by the number of days the cameras were operable. Each overcrossing camera was in continuous operation for 152 days. One of the cameras at the undercrossing was not turned on after a service visit which resulted in 14 days of no data collection. The average number of days that both undercrossing cameras were in operation was 175 days. To account for a single animal photo-captured by both cameras (i.e., a human on a horse using the entire overcrossing), the photos from both cameras at each crossing were combined. Then, the photo date and time was examined to ensure multiple occurrences of the same species were not recorded within a half hour time period.

We recorded 297 unique images on the Clinton Keith (Warm Springs) overcrossing. Coyote (Canis latrans) was the most common Covered Species (rate of occurrence = 0.41; 21% of photographs),

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-25 7.0 MONITORING ACTIVITIES

with San Diego Black-tailed Jackrabbit (Lepus californicus bennettii) being the only other Covered Species captured on the overcrossing (rate of occurrence=0.01; <0.00% of photographs). Cottontail species (Sylvilagus spp.) were the most commonly photo-captured animal (rate of occurrence = 0.57; 29% of the photographs). We photo-captured a variety of birds including Greater Roadrunner (Geococcyx californianus), Mourning Dove (Zenaida macroura), Say’s Phoebe (Sayornis saya), an unidentified flycatcher, and one California Ground Squirrel (Otospermophilus beecheyi) (rate of occurred for all = < 0.03; <2% of photographs). We captured images of butterflies and moths (rate of occurrence = 0.02; 0.01% of photographs) but could only identify them to Order (Lepidoptera). Finally, anthropogenic use of the overcrossing included human on horseback or on foot (rate of occurrence = 0.05; 2% of photographs). A large portion (41%) of the photos were not identified to species or genus.

We recorded 281 unique images on the Clinton Keith undercrossing. Coyote was the most common species (rate of occurrence = 1.06; 66% of photographs) followed by Bobcat (Lynx rufus) (rate of occurrence = 0.11; 7% of photographs). We saw less species richness at the undercrossing, with no documentation of San Diego Black-tailed Jackrabbit, identifiable bird species, California Ground Squirrel, butterflies, or moths. Anthropogenic use of the undercrossing was slightly higher than at the overcrossing (rate of occurrence = 0.05; 3% of photographs). Many photos (20%) were not identified to species or genus. The lack of sightings and species richness at the undercrossing is likely due to the removal of vegetation during construction of the Clinton Keith Road bridge over Warm Springs Creek. Currently, the substrate in this area is fibrous material with little to no vegetation growing through it. Data collected during the 5-year project period will elucidate how species use and richness change with vegetation maturation.

7.4.5 Long-tailed Weasel Survey Long-tailed Weasel (Mustela frenata) is a MSHCP covered mammal that occurs in almost all habitat types throughout the Plan Area. The MSHCP requires 75% occupancy in 18 Core Areas designated for Long-tailed Weasel as measured every eight years. Long-tailed Weasel currently occupy seven Core Areas (39%): Existing Core A, Existing Core C, Existing Core F, Existing Core H, Existing Core J, Existing Core K, and Proposed Core 2. To determine occupancy within the remaining 11 Core Areas, surveys that began in 2018, continued into 2019 and will continue until 75% occupancy has been confirmed or all Core Areas have been surveyed.

To select survey locations, a habitat model was created that included all suitable habitat types (i.e., excluding open water and desert scrub). Survey arrays were then randomly distributed across modeled suitable habitat on conserved lands. Each array was composed of four baited, semi- enclosed trackplate boxes, a standard detection method for target species with discernable tracks. Each array was visited five times over a two-week period.

In 2019, the Monitoring Program surveyed for long-tailed weasel at two Core Areas: Proposed Core 7 from January 2 to March 8, and Existing Core C from September 11 to November 1, for a total of 12 weeks (Figure 7-10. Long-tailed Weasel Station Locations in 2019). During those surveys, Northwestern San Diego Pocket Mouse (Chaetodipus fallax fallax), Spotted Skunk (Spilogale gracilis), deer mouse (Peromyscus spp.), woodrat (Neotoma spp.), Western Harvest Mouse (Reithrodontomys megalotis), Ringtail (Bassariscus astutus), California Ground Squirrel (Otospermophilus beecheyi), Gray Fox (Urocyon cinereoargenteus), and kangaroo rat (Dipodomys spp.) were detected. In November, we had one incidental observation of Long-tailed Weasel in the San Jacinto Wildlife Area.

Though Long-Tailed Weasel was not detected during this study, the lack of detection does not indicate they are absent from these Core Areas. To increase probability of detection, we may be able to enhance the current protocol by lengthening exposure time to sampling cubbies, using different bait, modifying the cubby type (i.e., open ended) and increasing lure. The Monitoring Program will continually research and test additional methodologies that may increase detectability.

7.4.6 Quino Checkerspot Butterfly Survey

The species-specific objectives for Quino Checkerspot Butterfly (Euphydryas editha quino; Quino) require annual documentation of presence and abundance at sentinel sites within the Conservation Area, and survey new areas with suitable habitat. The Monitoring Program has conducted surveys for Quino within the Conservation Area every year since 2005, with survey intensity depending on trained surveyor availability and annual habitat conditions. Biological Monitoring Program biologists attempted to meet this objective by focusing surveys within the six Core Areas identified in Conservation Objective 1: Warm Springs Creek, Johnson Ranch/Lake Skinner, Oak Mountain, Wilson Valley, Sage, and Silverado/Tule Peak. The Lake Mathews/Estelle Mountain/Harford Springs Core Area was historically occupied by Quino but the species is now extirpated (Dudek & Associates 2003) and surveys were not conducted there in 2019. Three previously established ‘sentinel sites’ across the Conservation Area known to support populations of Quino were monitored in order to assess flight season, presence/absence of larvae and/or adults, relative abundance, and available species-specific resources. These sentinel sites were located at the Southwestern Riverside County Multi-Species Reserve (MSR) in the Johnson Ranch/Lake Skinner Core Area; Oak Mountain in the Oak Mountain Core Area; and a site near Tule Peak Road in the Silverado/Tule Peak Core Area. Aside from the Core Areas surveyed, there were two non-core satellite occurrence complexes surveyed in 2019: San Bernardino National Forest and Cactus Valley.

To determine Quino distribution, searches for adult Quino were also conducted within 250 m x 250 m sampling stations at sites that have been occupied within the last ten years, sites where Quino historically occurred, and sites with suitable habitat in Core Areas. We surveyed from 13 February until 12 June. Our first sighting was of 16 adult Quino on 15 March at the Multi-Species Reserve (MSR) in the Johnson Ranch/Lake Skinner Core Area. Our last sighting was of two adult Quino on 29 May at the Silverado/Tule Peak Core area. Considering all Quino observations during the sentinel site visits, the Core area surveys, and the incidental observations, we detected a total of 199 individual Quino (Tables 7-7a and Table 7-7b; Figure 7-11. Quino Checkerspot Butterfly Occupied Survey Sites and Sentinel Sites in 2019). The percent-detection of Quino in 2019 was 14%. We observed Quino at all three sentinel sites and three (Johnson Ranch/Lake Skinner, Oak Mountain, and Silverado/Tule Peak) of the six Core Areas (Warm Springs Creek, Sage, Johnson Ranch/Lake Skinner, Oak Mountain, Wilson Valley, Silverado/Tule Peak) surveyed in 2019 (Figure 7-11).

The 2019 season was the 12th continuous survey year that the Silverado/Tule Peak Core Area was occupied. It continues to support the greatest number of Quino relative to other Core Areas, with a total of 78 adult Quino detected, followed by 7 in Oak Mountain, and 6 within the Johnson Ranch/Lake Skinner Core (Table 7-7a). No larvae were detected in any of the Core Areas in 2019.

We surveyed the Cactus Valley Satellite Occurrence Complex (Brown Canyon site) four times (18 sampling stations). At this complex, the Quino host plant Castilleja exserta was found in both small and large patches at all the sampling stations surveyed. Plantago erecta was found in large patches in ten out of the 18 sampling stations surveyed and Sairocarpus coulterianus was detected throughout six of the sampling stations. Plantago patagonica and Collinsia concolor were only found at a couple sampling stations. Despite the presence of host plants throughout the area, no Quino were detected (Table 7-7a).

Over the past 12 flight seasons (2008-2019), we have not detected Quino in the Warm Springs Creek Core Area despite the presence of robust patches of Plantago erecta in many areas, and large expanses of suitable habitat.

We did not find Quino at Magee Hills in 2019, the only survey site in the Sage Core Area. Over 12 years surveying this site, we have been successful at detecting a small but persistent population of Quino approximately 50% of the time. We did not find Quino in the Wilson Valley Core Area in 2019. Only one Quino has been detected in this Core Area over the past eight survey years.

Distribution of Quino was within the southern half of the Plan Area, bounded by the Cactus Valley Satellite Occurrence Complex Area to the north, Silverado/Tule Peak Core Area to the southeast, and the MSR sites to the west (Figure 7-11).

Overall, the 2019 flight season was more productive than the previous year, both in terms of survey effort and numbers of Quino detected. We observed 196 adult Quino (not including incidental sightings) during 168 surveys (includes sentinel and survey sites, mean = 1.17 Quino per visit). In 2018 Surveyors observed 84 adult Quino during 131 surveys (mean = 0.64 Quino per visit).

Over the last eight years, the flight season has extended over a 14-week period (26 January to 11 May). In both 2018 and 2019, the flight season extended over an 11-week period (9 March to 23 May in 2018; 15 March to 29 May 2019). A full description of survey methods and results can be found in the 2019 Quino Checkerspot Butterfly (Euphydryas editha quino) Survey Report included in Appendix A.

7.4.7 Delhi Sands Flower-loving Fly Survey The Delhi Sands Flower-loving Fly (Rhaphiomidas terminatus abdominalis; DSF) Conservation Objective 2 states that successful reproduction shall be documented at all Core Areas (Jurupa Hills, Agua Mansa Industrial Center, and Mira Loma (Dudek & Associates 2003) once a year for the first five years after permit issuance and then as appropriate, but not less frequently than every eight years thereafter. Reproductive success is defined in the MSHCP as the presence of pupal cases (exuviae) or newly emerged (teneral) individuals. The Teledyne property in the Jurupa Hills is the only Core Area that has been conserved to date. There are no lands that are currently part of the Conservation Area within the other two Core Areas for this species; however, the Rivers and

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-33 7.0 MONITORING ACTIVITIES

Lands Conservancy has been actively procuring lands in San Bernardino County in those general areas for DSF conservation.

In 2019, we used the same protocol in place since 2005, described more completely in the Western Riverside County MSHCP Biological Monitoring Program Protocol for Delhi Sands Flower- loving Fly Surveys. Line-transect surveys, designed to estimate population density of DSF using DISTANCE software, were conducted 5 July through 9 September in 2019. We divided the survey area into three sections (aggregate transect length range: 1,524 - 1,839 m) and surveyed each section once or twice a day depending on available personnel. We used number of observations to calculate density estimates and compare observations per kilometer surveyed across years. The Monitoring Program continues to maintain a weather station onsite, which was installed in June 2017. Data collected from this weather station will be used to track environmental variables that may correlate with DSF emergence and density. The 2020 survey season will provide three years of data collection with analysis provided in the 2020 Annual Report.

Biologists incidentally observed the first DSF at Teledyne on 3 July and the last DSF on 30 August 2019. Surveys ended on 9 September 2019. Adult DSF were observed on-transect on 123 occasions and off-transect on 18 occasions. Of those on-transect observations, 94 were male, 26 were female and three were of undetermined sex. Of the 141 individuals observed while conducting surveys, 23 were teneral (freshly molted). A total of nine exuviae (molted skeletons) were collected in 2019, all of which were collected during active surveys. The presence of tenerals and exuviae at the Teledyne site confirms reproduction. As noted in previous years, we detected most DSF individuals in the western section of the site where soils are generally more sandy and loose and vegetation is sparse. Furthermore, surveyors generally detected DSF on the edges of vegetation, rather than in the middle of the open sand dune or in the middle of thicker patches of shrubs or trees.

Density estimates and observations per km in 2019 increased considerably from 2018 (Figure 7- 12. Delhi Sands Flower-loving Fly Exuviae Detections at Teledyne in 2019). The daily density estimate in 2019 was 3.32 individuals/ha, which is comparable to the density in 2017 (3.4 individuals/ha). The number of DSF observations per km surveyed was 1.65 in 2019, which is significantly higher than 0.38 observations per km surveyed in 2018. The total number of survey hours in 2019 was 91.7 which is an increase from 56.6 hours in 2018 and is comparable to the 97.3 hours in 2017. The intentional increase in the survey hours from 2018 was done to increase the sample size in order to get a more accurate density estimate, while continuing to reduce potential impacts on teneral flies, which have been observed emerging from the sandy open spaces along the line transects. In 2019 the average speed of surveyors was 0.95 km per hour. Across the 11 years we have performed transect surveys, the average walking speed of surveyors has been

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-34 7.0 MONITORING ACTIVITIES

between 0.7 to 1.4 km/hour. There appears to be no correlation between observer speed and annual density estimates.

Habitat management activities initiated at Teledyne since 2015 by the MSHCP Management Program seem to be preliminarily successful at improving site conditions for DSF, as evidenced by the species increased use of the eastern portion of the study site. A full description of survey methods and results can be found in the 2019 Delhi Sands Flower-loving Fly (Rhaphiomidas terminatus abdominalis) Survey Report included in Appendix A.

7.4.8 Arroyo Chub Survey The species objective for Arroyo Chub (Gila orcutti) requires documenting the presence of this fish in 75% of its identified Core Areas in the Santa Ana and Santa Margarita watersheds (Figure 7-13. Arroyo Chub Survey Locations and Detections in 2019). The frequency of Arroyo Chub surveys to document presence are not defined in the monitoring objectives; therefore, the Program defaults to conducting surveys every eight years. In 2019, the Monitoring Program electro-fished for Arroyo Chub at Mill Creek in the Prado Basin. Due to high water levels in the winter of 2018, surveys at Mill Creek had been postponed to 2019. No native fish or amphibians were detected in this Creek in 2019. Numerous invasive fish, including Black Bullhead (Ameiurus melas), Yellow Bullhead (Ameiurus natalis), Common Carp (Cyprinus carpio), Mosquitofish (Gambusia affinus), Green Sunfish (Lepomis cyanellus), Bluegill (Lepomis macrochirus), Inland Silversides (Menidia beryllina), Largemouth Bass (Micropterus salmoides), Fathead Minnow (Pimephales promelas), Sailfin Molly (Poecilia latipinna), and White Crappie (Pomoxis annularis) were captured and removed. A few Bullfrogs (Lithobates catesbeianus) and many Red Swamp Crayfish (Procambarus clarkii) were also captured and removed.

In 2019, incidental Arroyo Chub records (n=94) were collected by Monitoring Program biologists in Sunnyslope Creek (a tributary of the Santa Ana River) while assisting the Santa Ana Watershed Association/Orange County Water District survey for Santa Ana Sucker (Catostomus santaanae) in this Creek; and in the Santa Ana (n≈100) and San Jacinto Rivers (n≈70) while conducting Riparian Bird surveys.

CDFW personnel surveyed fish in the waterways of the San Jacinto Mountains in 2018 and 2019 and did not detect Arroyo Chub (Jennifer Hemmert of CDFW, personal communication). These surveys are ongoing and will be continued in 2020. CDFW and California Trout, Inc. are planning an extensive invasive fish removal effort in the Santa Margarita River in 2020 and may confirm the presence of Arroyo Chub in that waterway during those efforts.

7.4.9 Vernal pool survey There are three covered fairy shrimp species and one covered amphibian species that inhabit vernal pools in the MSHCP Plan Area: Riverside Fairy Shrimp (Streptocephalus woottoni), Santa Rosa Plateau Fairy Shrimp (Linderiella santarosae), Vernal Pool Fairy shrimp (Branchinecta lynchi), and Western Spadefoot (Spea hammondii). Although species-specific survey objectives are not listed for fairy shrimp, the default MSHCP monitoring objective states that species presence and continued use shall be maintained at 75% of the listed Core Areas, as measured at least once every eight years. The species objectives for Western Spadefoot require maintaining successful reproduction at 75% of conserved breeding locations once every eight years. Previous survey efforts for these species focused on locating vernal pools in the Conservation Area, assessing the suitability of pools for target species, and documenting species presence within Core Areas and other potentially suitable habitat in the Conservation Area.

In 2019, after above average winter rainfall in western Riverside County, Monitoring Program biologists conducted focused surveys in vernal pools on properties acquired within the last year, or those where the target species have not been detected within the 8-year survey window for the species. After biologists scouted potential target areas, suitable pools were surveyed in Anza, the Estelle Mountain Preserve, Lake Elsinore, West Hemet, Perris, and the French Valley area. Center for Natural Lands Management (CNLM) biologists surveyed the Skunk Hollow and Johnson Ranch pools in Murrieta (Figure 7-14. Vernal Pool Survey Locations Surveyed During 2018- 2019).

Combining observations made by the Monitoring Program, Glenn Lukos Associates, and CNLM biologists, Riverside Fairy Shrimp has been detected at two of five Core Areas during the last 8- year period: Skunk Hollow (2019) and Murrieta (Schleuniger Pool; 2019). The Alberhill and Santa Rosa Plateau Core Areas have been listed in error according to the USFWS, as there are no historical records from these areas for this species. Riverside Fairy Shrimp were also detected in 4 pools outside of the Core Areas during this time period, at the Anheuser Busch property near Murrieta (2017), the French Valley Donation (2019), the Multi-Species Reserve (2017), and El Sol (2017).

Vernal Pool Fairy Shrimp have been detected at two Core Areas during the 8-year period: The Santa Rosa Plateau (2016) and Skunk Hollow (2019). The Salt Creek Core Area was surveyed in 2018, but no Vernal Pool Fairy Shrimp were detected. Ideally, future land acquisition will include more pools in this area. As written, the species objective for Vernal Pool Fairy Shrimp will not be met until the species is found in all three of its Core Areas.

Santa Rosa Plateau Fairy Shrimp were detected by Monitoring Program biologists at its only Core Area, the Santa Rosa Plateau, in 2017, fulfilling the species objective until 2025.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-39 7.0 MONITORING ACTIVITIES

Breeding evidence for Western Spadefoot was detected in 2019 in Murrieta (Proposed Core 2), French Valley, the Estelle Mountain Preserve, and incidentally in the Badlands and at Skunk Hollow by CNLM biologists. As of 2019, the species objective has not been met for this species, having been found in only 11(68.7%) of its 16 Core Areas. These Core Areas are Lake Perris/San Jacinto Wildlife Area, Lake Skinner/Diamond Valley Lake, Skunk Hollow, Potrero Valley/Soboba, the Badlands, Vail Lake/Aguanga, San Jacinto Mountains, Highgrove, San Jacinto River, Murrieta (Proposed Core 2), and the Estelle Mountain Preserve.

7.4.10 Rare Plant Survey There are 63 rare plants classified as Covered Species under the MSHCP. For most of these species, the MSHCP requires confirmation of a specific number of occurrences, often at specified sites, within the Plan Area. Unless a given species-specific conservation objective has more rigorous requirements, the Biological Monitoring Program is obligated to survey for the distribution of covered plant species at least once every eight years with the goal of verifying occupancy at 75% or more of the sites listed in the species objective. Some Covered Species have additional “demonstrate-conservation” objectives that require documentation of a specific level of conservation, such as confirmation of a minimum number of individuals.

Monitoring Program biologists have surveyed historical locations within the Plan Area for targeted plant species every year since permit issuance. This effort was necessary due to the varying sources, precision, and age of historical records and the need to verify the status of covered plant species in the Plan Area. Target plant species chosen for monitoring within a given year depend upon whether or not known locations for Covered Species have been verified during the current reporting period, the detectability of rare annual species given recent environmental conditions (e.g., rainfall), and availability of trained personnel. Additionally, they are chosen because they either are observed and abundant during a sentinel survey, or because they are known to co-occur in the area being surveyed, with higher priority given to species with unmet objectives, and species with “demonstrate-conservation” objectives.

Three types of rare plant surveys were conducted in 2019: sentinel site surveys to monitor the phenology of target plant species and guide the timing of searches for covered plant species at other locations; inventory surveys to locate unconfirmed occurrences on recently conserved land; and long-term monitoring surveys to verify persistence at historical locations. Depending upon available information and survey goals, surveyors in 2019 either navigated to assigned 250 meter x 250 meter grid cells containing historically documented occurrences of targeted plant species or conducted surveys directly around known occurrences queried from the Monitoring Program’s database. Assigned cells or survey locations were searched until all species of interest were located or all suitable habitats were thoroughly searched. Although each survey focused on particular target species, surveyors remained vigilant for all Covered Species. In 2019, Monitoring Program biologists conducted a total of 225 individual rare plant surveys (85 monitoring surveys, 126 inventory surveys, and 14 sentinel site surveys) at 205 grid cells, targeting 23 MSHCP covered rare plant species

The primary objective of the 2019 rare plants survey season was to reconfirm meeting the conservation objectives listed in Table 9-3 of the MSHCP (Volume I) for 13 plant species with objectives having additional requirements for population size. Of the Covered Species with these additional requirements, 9 of 10 that had been previously met were reconfirmed in 2019, but

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-42 7.0 MONITORING ACTIVITIES

Chickweed Oxytheca (Sidotheca caryophylloides) could not be surveyed this season due to the closure of Highway 243. Of the other 3 species, objectives for Cliff Cinquefoil (Potentilla rimicola) and California Muhly (Muhlenbergia californica) have never been met because all but one of the known occurrences are located outside the Plan Area. We did not conduct surveys for these in 2019. Last, Mojave Tarplant (Deinandra mohavensis) was observed in abundance in 2019, but the species objective "at least four localities…occupying at least 100 acres" requires further interpretation before we can determine whether the conservation objective has been met, as this species tends to grow in a linear pattern along drainages, not in large patches that can be measured in acreage.

In addition to surveys targeting Table 9-3 of the MSHCP (Volume I) rare plants, Monitoring Program personnel conducted surveys that confirmed presence at 56 distributional objective sites for 25 Covered Species. Some of these distributional objectives were met concurrent with “Table 9-3” demonstrate-conservation objectives, and other species were not targeted, but were observed co-occurring with targeted species. We also confirmed another 16 distributional objective occurrences for 11 Covered Species through incidental observation during unrelated survey efforts.

For details about locations of rare plant species observed by Monitoring Program biologists in 2019 and a full description of survey methods and species objectives refer the 2019 Rare Plants Survey Report included in Appendix A.

7.4.11 Brand’s Phacelia Habitat Enhancement

The MSHCP requires conservation of two occurrences of Brand’s Phacelia (Phacelia stellaris), a Narrow Endemic Plant, along the Santa Ana River. However only one of these populations, which occurs in the Santa Ana Wilderness Area, was extant at the time of MSHCP implementation.

The objective of the Habitat Enhancement Project is to improve the habitat of the sole remaining population within the MSHCP Plan Area by removing non-native competitors and controlling habitat disturbance. Results of this project will advise future habitat management for this site.

The 2019 season was the third year of the Brand’s Phacelia Habitat Enhancement Project. The study design uses a randomized block distribution in which each study plot (n = 48) was assigned one of four treatments: Weeding, Disturbance (raking the soil), Weeding and Disturbance, or Control (no treatment applied). Treatments for 2019 surveys were applied in December 2018 and January 2019. The first individuals of Brand's Phacelia germinated in December 2018 and surveys occurred from January through March 2019. A total of 53 Phacelia plants germinated within study plots and 47 germinated outside of plots. Plants that grew outside of plots were monitored but their data was not included in statistical analyses. Of plants germinated within plots, 79% occurred in

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-43 7.0 MONITORING ACTIVITIES

either Disturbance or Weeding and Disturbance plots. Though there appears to be a strong correlation with disturbance, these results were not statistically significant due to the low number of individuals. Mean width and reproductive vigor (number of inflorescences per plant), however, was statistically different across plot treatments, with Weeding and Disturbance plots having the largest and most reproductive individuals, and Disturbance plots running second, having slightly fewer.

Vegetation in the plots was measured using a point intercept survey consisting of 32 points, arranged in an 8 m x 4 m grid, overlaid on each plot. Individual plants of all species and all ground cover types (bare, litter, moss/crust, and other) were recorded at each of the 32 points within each plot. These data were collected after Phacelia surveys were completed and have not yet been analyzed for potential correlations.

The 2019 season was the first year that enough plants germinated to begin statistical analysis. We expect that one or two more years of data will be needed to make appropriate management recommendations for this population. At that time, a complete data analysis will be conducted and a comprehensive report will be produced. In December 2019, plot treatments began in preparation for the 2020 survey year of the Brand’s Phacelia Habitat Enhancement Project. A full report will be produced when the project ends.

7.4.12 Incidental Species Sightings Plant and animal Covered Species incidentally observed during unrelated survey activities are recorded by Monitoring Program biologists to increase knowledge of the distribution of Covered Species in the Conservation Area. Incidental observations are different than focused survey data as the methods are not standardized and only positive data are recorded. However, recording incidental observations of species that are difficult to detect is extremely important. Incidental observation data may be used as current documentation of species presence at a given location, as a starting point for future focused survey efforts, and to provide information about appropriate habitat for the detected species in the future.

Incidental observations of Covered Species made during surveys in 2019 were entered into the Monitoring Program’s centralized database and these data were incorporated into taxa-specific reports. All observations of Covered Species, whether made by focused survey or incidentally, are used when making a determination of whether or not species-specific objectives have been met for a given reporting period.

The species objectives for Burrowing Owl require the conservation of five Core Areas, plus interconnecting linkages, containing a breeding population of 120 owls with no fewer than five pairs in any one Core Area. The Core Areas listed in the Plan are: Lake Skinner/Diamond Valley Lake (which includes the El Sol and Johnson Ranch properties), playa west of Hemet, San Jacinto Wildlife Area/Mystic Lake area including Lake Perris, Lake Mathews, and along the Santa Ana River.

Since 2006, the RCA’s Management Program and Monitoring Program have collaborated with local Reserve Managers on an adaptive management project with the goal of increasing Burrowing Owl habitat within the Conservation Area. This collaborative effort has grown to include management and monitoring of natural and artificial burrows at the Southwestern Riverside County Multi-Species Reserve, Lake Mathews/Estelle Mountain Reserve, El Sobrante Landfill, Lake Perris State Recreation Area, Johnson Ranch, San Jacinto Wildlife Area, and El Sol property. Reserve Managers have installed artificial burrows and managed vegetation within several Core Areas to facilitate Burrowing Owl use of Core Areas, including installing at least 77 burrows within the Lake Skinner/Diamond Valley Lake Core Area, at least 7 in the San Jacinto Wildlife Area/Mystic Lake Core Area including Lake Perris, and at least 52 in the Lake Mathews Core Area. Cooperation with Reserve Managers has expanded to include a schedule and shared data sheet for monitoring Burrowing Owl burrows. The collected data are stored in a Monitoring Program database.

Based on surveys in recent years by the Monitoring Program, Management Program, and Reserve Managers, only the Lake Skinner/Diamond Valley Lake Core Area currently supports the minimum number of breeding pairs of Burrowing Owls. Burrowing Owls need open areas with sparse or low growing vegetation. Therefore, appropriate active management tools may be needed to control non-native grasses (e.g., grazing, mowing, prescribed fire). These management actions would likely benefit several other Covered Species such as Stephens’ Kangaroo Rat and Mountain Plover. A comprehensive Burrowing Owl Habitat Management Plan for western Riverside County has been drafted in collaboration with local Reserve Managers. A Burrowing Owl Translocation Program document is also being developed. To achieve the conservation objectives for Burrowing Owl, management of habitat within the remaining Core Areas and active translocation of owls will likely be necessary. Additional land that supports Burrowing Owls may also need to be acquired.

Riparian Birds. Continue to include in survey efforts recently acquired properties that appear to contain suitable habitat for targeted riparian bird species. Two of our Chat nests in 2019 occurred on such properties and helped us to meet the reproductive objective for the species. Beyond this, the methods used in 2019 allow detection of the focal species within one or two visits to survey sites, so these metjods should be continued in future survey efforts. The Murrieta Creek Core Area does not currently contain conserved land that is likely to be used by breeding Yellow Warblers, as evidenced by the fact that we have detected warblers here only once in the last five years. Suitable breeding habitat exists within the Core Area boundaries, and if this land is acquired for conservation, we would likely be able to add Murrieta Creek to the list of Core Areas in which we regularly detect Yellow Warblers.

The parcel in the Temecula Creek Core Area in which we detected Yellow-breasted Chat fledglings contains ideal breeding habitat for the species. Immediately east of this parcel is continuation of the habitat, and its acquisition for conservation should be considered, if possible.

As outlined in the Results section of this report, there are three non-Core Areas where we regularly detect Yellow Warblers, and these should be considered as alternative Core Areas for the species, especially if the Murrieta Creek and Vail Lake Core Areas continue to lack riparian habitat or present access difficulties, respectively. These areas are Lake Mathews/Estelle Mountain (Existing Core C), Lake Perris/Mystic Lake (Existing Core H), and Lake Skinner/Diamond Valley Lake (Existing Core J). Similarly, Lake Mathews/Estelle Mountain and Lake Skinner/Diamond Valley Lake should be considered as alternative Core Areas for Yellow-breasted Chat, especially if our Program will not be granted access to Vail Lake.

Finally, continued efforts should be made to acquire access to conduct surveys in the Vail Lake Core Area, specifically within the vicinity of the lake itself. This is a Core Area for Yellow Warblers and Yellow-breasted Chats, and suitable habitat may exist, but we are unable to make this determination without being able to access the site.

Quino checkerspot Butterfly. Differences in habitat condition between occupied and unoccupied sites are not completely understood in the Plan area, and more research is needed to determine what factors affect Quino distribution. As climate change effects continue it will be important to survey suitable habitat at higher elevations, as these may serve as expansion areas, or refugia, for Quino populations no longer occupying hotter and drier habitats at lower elevations. Where Quino host plant locations are known, especially in the higher elevations, it may be useful to scout these areas for Quino occupancy to increase our knowledge of their distribution and population size.

Quino has not been detected in the Warm Springs Creek Core Area over the past 11 years of survey efforts. A wildlife bridge that spans Clinton Keith Road has recently been constructed which may

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-46 7.0 MONITORING ACTIVITIES

facilitate Quino movement between formerly fragmented habitats. Surveys at sampling stations near the overcrossing are planned in an effort to detect Quino colonization and document habitat attributes. The Beauty Mountain site, managed by BLM, has had marijuana grows near Quino locations. It is recommended that this site be regularly monitored for illegal activity, which could threaten the known Quino population, as well as any as yet undiscovered Quino populations in that area. The Oak Mountain Core Area is one of the best remaining areas for Quino. It would benefit the species if land were conserved on the top of Oak Mountain and along the ridgeline where some of the best Quino habitat is located.

Delhi Sands Flower-loving Fly. Given the endangered status of the species and the minimal effort required to document successful reproduction at the sole occupied site within the Plan Area, we recommend continuing to monitor the Delhi Fly annually as long as personnel are available.

We plan to conduct the more demanding line-transect study again in 2020 to continue to monitor effects of management activities and Delhi Fly population fluctuations. Vegetation and soil characteristics should continue to be monitored in conjunction with ongoing management actions conducted as described by the Delhi Sands Flower-loving Fly Habitat Management Plan and Delhi Sands Flower-loving Fly Habitat Management Update.

In addition to the vegetation surveys, we recommend continuing to perform ground-dwelling arthropod surveys in order to track the relative abundance and richness of the arthropod community, which the predacious Delhi Fly larvae presumably utilize as a food resource (Ken Osborne, consultant, personal communication and Rick Rogers, entomologist, personal communication). These data could additionally serve as a habitat quality indicator of the Delhi sand dunes at Teledyne.

Covered Amphibians and Aquatic Reptiles. Exotic species such as Bullfrogs, Red-Eared Sliders, Mosquito Fish, and African Clawed Frogs exist within many waterways within the Conservation Area and have significant negative impacts on native amphibians and aquatic reptiles by direct predation and competition for limited resources. At a minimum, the habitat within Core Areas that are infested with exotic species would be greatly enhanced by removal of these exotics. Although reintroduction of some covered amphibians may be an appropriate management action (e.g., Mountain Yellow-Legged Frog), no reintroductions of Covered Species should be considered for areas currently infested with exotic species until management actions have controlled or eradicated exotic species. Monitoring Program biologists have participated in MSHCP Management Program led efforts to locate and exterminate aquatic exotic species on RCA- managed properties when possible. Further details can be found in Section 6.0 – Management Activities of this report.

Western Riverside County MSHCP Annual Report (January 1, 2019 through December 31, 2019) 7-47 7.0 MONITORING ACTIVITIES

No California Red-Legged Frogs (Rana draytonii) have been found in western Riverside County since one male was seen in Cole Creek at the Santa Rosa Plateau Ecological Reserve in September 2003. The species is not known to currently occur in the Plan Area despite the apparent presence of suitable habitat. Significant effort was expended by the Monitoring Program during the Inventory Phase to survey for Red-Legged Frog within Core Areas, and to evaluate and identify suitable habitat for Red-Legged Frog within the Conservation Area. The probable causes of the decline of Red-Legged Frog are introductions of non-native predators such as Bullfrogs and fish, habitat loss due to development and agriculture, pesticide pollution, and pathogens such as Chytrid Fungus (Batrachochytrium dendrobatidis). Without future active management (e.g., exotic species removal, species translocation) extensive additional efforts to locate Red-Legged Frogs within the Conservation Area would be an inefficient expenditure of resources. USGS is currently spearheading a relocation effort outside of the county that may be applicable to the Plan area in the future.

In addition to documenting the distribution of Southwestern Pond Turtle (Emys marmorata pallida) populations throughout western Riverside County, the current turtle trapping protocol might be amended to include population estimates. Population estimates would enable Reserve Managers to better monitor the status of pond turtle populations over time and could potentially provide valuable information regarding population responses to management actions. Furthermore, a comprehensive assessment of upland habitat usage would help facilitate appropriate management. This would involve a more thorough evaluation of landscape composition, such as collecting parameters of upland slope and distance to suitable nesting locations. Because pond turtles do not nest in the aquatic system itself, it is important to assess all of their habitat requirements to most effectively manage for sustainable populations within the Conservation Area.
