1.0 Executive Summary
This baseline biological resource report has been prepared for the Proctor Valley (South) parcel of the Otay Ranch Preserve. The Otay Ranch Preserve is located both within the city of Chula Vista and in an unincorporated portion of southwestern San Diego County east of the city of Chula Vista. The Proctor Valley (South) parcel is located within unincorporated San Diego County.
During the spring of 2014, RECON biologists conducted surveys to gather baseline biological information at the Proctor Valley (South) parcel. The surveys consisted of vegetation mapping and general plant and wildlife surveys. Sensitive species were observed incidentally, and suitable habitat for sensitive wildlife species was evaluated.
Four unique types of vegetation stands as defined by the San Diego Association of Governments were mapped in the Proctor Valley (South) parcel. Of these, three vegetation communities are considered Tier II Uncommon Uplands by the City of Chula Vista’s Multiple Species Conservation Program Subarea Plan. Within these four vegetation stands, a total of 69 native plant species and 21 non-native plant species were observed. Three of the native plant species are considered sensitive. Wildlife species observed include 6 invertebrates, 5 reptiles, 29 birds, and 7 mammals. Of these, two reptiles, five birds, and two mammals are considered sensitive.
The baseline data gathered during these surveys will be used to guide future prioritization of Otay Ranch Preserve management actions. Future focused surveys for rare plants, coastal California gnatcatcher (Polioptila californica californica), and Quino checkerspot butterfly (Euphydryas editha quino) have been recommended within the Proctor Valley (South) parcel as a task in the Fiscal Year 2014–15 Annual Work Plan for Conveyed Lands Managed by the Otay Ranch Preserve Owner/Manager (RECON 2014).

2.0 Introduction
This baseline biological resources report has been prepared for the Preserve Owner/Manager (City of Chula Vista and County of San Diego) to be used in support of the Otay Ranch Resource Management Plan (RMP). The Otay Ranch Preserve (Preserve) is currently composed of eleven parcel sets: Proctor Valley (South), Proctor Valley (North), Wolf Canyon, Dulzura, Jamul Mountains, Little Cedar Canyon, McMillin, Salt Creek, Northern San Ysidro, San Ysidro, and Millenia. This baseline biological resource report has been prepared for the Proctor Valley (South) parcel.
Otay Ranch Preserve is located in southwestern San Diego County. The Proctor Valley (South) parcel is located in unincorporated lands in southeastern San Diego County, east of Proctor Valley Road, west of Campo Road, and north of Lower Otay Reservoir (Figures 1 and 2). The Proctor Valley (South) parcel encompasses approximately 40 acres within Assessor’s Parcel Number 598-020-05.
One unnamed drainage is present in the Proctor Valley (South) parcel. The unnamed drainage is located in the southwest corner of the parcel and flows from east–southeast to west–northwest (Figure 3). This drainage connects to a separate drainage located off-site along Proctor Valley Road and empties into Upper Otay Reservoir. The Jamul Mountains, where the Proctor Valley (South) parcel is located, have historically been known to support a variety of species and habitats, many of which are considered to be sensitive in California (CDFW 2011, 2014; Consortium of California Herbaria 2010).
Since 1950, portions of the Proctor Valley (South) parcel have burned six times: in 1968, 1980, 1984, 2003, 2005, and 2007 (California Department of Forestry and Fire Protection 2013; Attachment 1: Figure 4). Vegetation communities within the Proctor Valley (South) parcel are in the process of recovering from these disturbances.
RECON biologists conducted surveys to gather baseline biological information at the Proctor Valley (South) parcel during the spring of 2014. The surveys consisted of vegetation mapping and general plant and wildlife surveys. Sensitive species observed incidentally during general plant and wildlife surveys were mapped using global positioning system (GPS). The Proctor Valley (South) parcel was evaluated for the presence of suitable habitat for sensitive wildlife species to determine if future focused surveys should be proposed. Recommendations for the types of focused surveys to be conducted are discussed in Section 5.0. The baseline data gathered during these surveys will be used to guide future prioritization of Preserve management actions.

3.0 Survey Methods
3.1 Literature and Database Review
Prior to conducting the surveys, literature and databases were reviewed from various resources in an effort to utilize multiple sources of historical data on the flora and fauna present within the parcel or the vicinity. Resources that were reviewed included the California Natural Diversity Database (CNDDB; CDFW 2011, 2014), the Consortium of California Herbaria (2010), and San Diego Association of Governments (SANDAG) vegetation maps (SANDAG 2012). Species sensitivity status was determined using the Otay Ranch Preserve Phase 1 and Phase 2 RMPs (County of San Diego 1993, 2002), the City of Chula Vista Multiple Species Conservation Program Subarea Plan (MSCP) (City of Chula Vista 2003), the California Department of Fish and Wildlife’s (CDFW’s) Special Vascular Plants, Bryophytes, and Lichens List (CDFW 2014) and Special Animals List (CDFW 2011), and the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Plants (CNPS 2014). Rare Plants of San Diego County (Reiser 2001), A Flora of San Diego County (Beauchamp 1986), and the Jepson Online Interchange (University of California 2014) were reviewed for historical presence and species descriptions of plants that may occur within the Proctor Valley (South) parcel.
3.2 Botanical Resources
RECON personnel mapped vegetation communities and compiled an inventory of the flora within the Proctor Valley (South) parcel. Survey dates and personnel for botanical resources are presented in Table 1. The results of these surveys are discussed separately in Section 4.0, Proctor Valley (South) Parcel Existing Conditions and Survey Results.

3.2.1 Vegetation Communities
The main objective of mapping vegetation was to identify vegetation communities suitable for sensitive plants and wildlife occurrences and to guide future Preserve management decisions. Communities were mapped on 1-inch-equals-120-feet aerial photographs taken in May 2012. The SANDAG 2012 vegetation maps were used as a reference for the updated 2014 mapping within the Proctor Valley (South) parcel.
Vegetation communities were mapped using the Vegetation Classification Manual for Western San Diego County (referred to as SANDAG vegetation communities; Sproul et al. 2011), which is based on A Manual of California Vegetation (Sawyer et al. 2009). A crosswalk to the Holland (1986) classification system as modified by Oberbauer (2008) has been prepared and is included in Section 4.5.1 to compare the SANDAG vegetation communities to the City of Chula Vista MSCP habitat tiers.
Prior to conducting field work, the surveying biologist examined multiple aerial photographs of the survey areas from differing seasons and years. Observable vegetation patterns were outlined on an aerial photograph (e.g., areas that appeared to have grassland vegetation and coastal sage scrub). The preliminary mapping was ground-truthed, and boundaries were either confirmed or revised in the field during a series of surveys between April and May 2014. The species present in each vegetation community were recorded on datasheets. Surveyors walked meandering transects through the range of habitats and other conditions present within the Proctor Valley (South) parcel.
3.2.2 Plant Surveys
A general plant list was compiled in conjunction with vegetation mapping. The vegetation community in which each species occurred was documented. All plant species observed at the time of the surveys were recorded. Floral nomenclature for species is consistent with the Jepson Online Interchange (University of California 2014). Species that could not be readily identified in the field were collected or photographed and identified using a taxonomic key. Although focused sensitive plant surveys were not conducted, sensitive plant species identified during the general plant surveys were mapped using a handheld Trimble® GPS unit. The sensitivity ranking of plant species is based primarily on County of San Diego Otay Ranch Phase 1 and Phase 2 RMPs (1993 and 2002), the City of Chula Vista MSCP Subarea Plan (2003), the CDFW Special Vascular Plants, Bryophytes, and Lichens List (2014), and the CNPS Inventory of Rare and Endangered Plants (2014).
Page 10 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
Assessments for the potential occurrence of sensitive plant species are based upon species occurrence records from the CNDDB within a two-mile radius of the Proctor Valley (South) parcel and literature review. Likelihood for occurrence within the Proctor Valley (South) parcel was evaluated based on habitat requirements such as soil, range, the timing constraints of the surveys, and visibility restrictions.
3.3 Wildlife
RECON personnel conducted baseline wildlife surveys to (1) identify species assemblages associated with various post-burn vegetation communities and (2) identify any indicator species that may correspond with particular floristic and/or structural habitat characteristics. Survey dates and personnel for the baseline surveys are presented in Table 2.

3.3.1 General Wildlife Surveys
During the baseline survey, the wildlife biologist walked meandering transects through the range of habitats and conditions (e.g., hydrology, topography) within the survey area. Each habitat type was surveyed. Survey effort was allocated among a range of weather conditions conducive to activity by the various target taxa (e.g., on a cool morning for birds, during warm weather for reptiles and butterflies).
All wildlife species apparent at the time of the surveys were recorded. Individuals of the following taxa were surveyed during inventories: butterflies, reptiles, birds, and mammals. All animal species were observed visually or detected from calls, tracks, scat, or nests. Because surveys were performed during the day, nocturnal animals were identified only by sign such as scat or tracks. Bird species and often other species were annotated to habitat association. Any sensitive wildlife species identified during the general wildlife surveys were also recorded.
Assessments for the potential occurrence of sensitive wildlife species are based upon species occurrence records from the CNDDB within a two-mile radius of the survey
Page 11 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
area. Likelihood for occurrence was evaluated based on habitat requirements, range, and the timing constraints of the surveys.
Zoological nomenclature for invertebrates is in accordance with Mattoni (1990) and Opler and Wright (1999); for amphibians and reptiles with Crother (2001, 2008) and Crother et al. (2003); for birds with the American Ornithologists’ Union Checklist (1998) and Unitt (2004); and for mammals with Baker et al. (2003) and Hall (1981). Assessments of the sensitivity of wildlife species are based primarily on County of San Diego Otay Ranch Phase 1 and Phase 2 RMPs (1993 and 2002), City of Chula Vista MSCP Subarea Plan (2003), and CDFW Special Animals List (2011).
4.0 Proctor Valley (South) Parcel Existing Conditions & Survey Results
4.1 Topography
The 40-acre Proctor Valley (South) parcel occurs within the Jamul Mountains. The topography consists of a steep south-facing mountain slope with minimal flat ground along the toe of the slope. Elevation ranges from 940 feet within the unnamed drainage in the southwestern corner of the parcel to 1,420 feet at the ridge top in the northeast corner of the parcel. The topography of the Proctor Valley (South) parcel is shown in Attachment 1: Figure 5.
4.2 Soils
One soil series occurs in the Proctor Valley (South) parcel: Friant (Attachment 1: Figure 6). The acreage of this soil series is listed in Table 3.
• The Friant series consists of shallow and very shallow, well-drained fine sandy loams that formed in material weathered from fine-grained metasedimentary rock (USDA 1973).

Page 12 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
4.3 Rainfall
The 2013–2014 wet season (September through June) had well below average rainfall totals. Scattered light fall rains occurred from October through mid-December. After the fall rains, warm and dry conditions developed in late-December and into January. Almost no rain events occurred in late-December and January. Most of the individual rain events brought only brief periods of light or very light precipitation. Rainfall data presented in Table 4 are from the weather station at Brown Field (National Weather Service 2014). A total of 4.21 inches of rain fell at this weather station during the 2013– 2014 wet season. The most productive rain event occurred between February 27 and March 3 and totaled 1.76 inches.

SOURCE: National Weather Service (2014) 4.4 Photographic Monitoring
Fifteen photographic monitoring points were established within the Proctor Valley (South) parcel during the baseline surveys (Attachment 1: Figure 7). The photo monitoring point locations were chosen so that they would provide a broad view of representative vegetation communities. Prominent features were mindfully placed in each photo to make relocating the exact location easier in future years. The prominent features were chosen so that changes to the landscape (i.e., fire, weed encroachment, or native shrub growth) would minimize change to the visibility of the feature. The locations were recorded with a Trimble® GPS.
4.5 Botanical Resources
Botanical resources include vegetation communities and plant species within those habitats. The following section provides the results of the 2014 vegetation mapping and plant species inventory within the Proctor Valley (South) parcel.

4.6.4 Mammals
A total of seven mammal species were observed/detected within the survey area. Two species are considered sensitive: San Diego black-tailed jackrabbit (Lepus californicus bennettii) and southern mule deer (Odocoileus hemionus) (see Section 4.7.5, Sensitive Mammals). Five common mammal species observed within the survey area include coyote (Canis latrans), California ground squirrel (Spermophilus beecheyi), cottontail (Sylvilagus sp.), dusky-footed woodrat (Neotoma fuscipes), and Botta’s pocket gopher (Thomomys bottae).
4.7 Sensitive Species
Sensitive species were observed incidentally during baseline plant and wildlife surveys. For the purposes of this report, a species is considered sensitive if it is: (1) listed by state or federal agencies as threatened or endangered or are candidates or proposed for such listing; (2) considered rare, endangered, or threatened by the State of California (CDFW 2011, 2014); (3) a narrow endemic or covered species in the MSCP (City of Chula Vista 2003); (4) considered by CNPS to have a California Rare Plant rank of 1B or 2 (CNPS 2014); (5) listed within the Otay Ranch Preserve RMPs (County of San Diego 1993, 2002); or (6) considered rare, sensitive, or noteworthy by local conservation organizations or specialists. Noteworthy plant species are considered to be those that are considered by CNPS to have a California Rare Plant rank 3 or 4. Sensitive habitat types are those identified by the City of Chula Vista MSCP. Assessments for the potential occurrence of sensitive or noteworthy species are based upon species occurrence records from the CNDDB, Consortium of California Herbaria, and a literature review.
Sensitive plant species observed within the survey area are shown on Attachment 1: Figure 9, and sensitive wildlife species are shown on Attachment 1: Figure 10. Sensitive plant and wildlife species that were observed and/or have a potential to occur within the survey area are listed in Attachment 5 and Attachment 6, respectively.
4.7.1 Sensitive Plant Species
Three sensitive plant species were identified in the Proctor Valley (South) parcel. Eleven other sensitive plant species have the potential to occur (see Attachment 5). Species that are ephemeral perennials or annual herbs may not have been detected due to drought conditions that developed in 2014 (see Section 4.3).
Sensitive plant species that were observed are discussed below and in Attachment 5. Additional sensitive plant species that were not observed during the surveys but have low to high potential for occurrence are also described in Attachment 5.
Page 19 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
San Diego County viguiera (Bahiopsis =[Viguiera] laciniata). This perennial shrub is an RMP species to be monitored and has a CNPS ranking of 4.2 (uncommon in California; fairly endangered in California; CNPS 2014). This species occurs commonly within the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub). It also is present within the Artemisia californica– Eriogonum fasciculatum–Malosma laurina Association and Malosma laurina–Lotus scoparius Association.
San Diego needle grass (Stipa diegoensis [=Achnatherum diegoense]). This perennial herb is an RMP species to be monitored and has a CNPS ranking of 4.2 (uncommon in California; fairly endangered in California; CNPS 2014) (Attachment 2: Photograph 8). This species occurs occasionally in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
Decumbent goldenbush (Isocoma menziesii var. decumbens). This perennial shrub has a CNPS ranking of 1B.2 (rare, threatened, or endangered in California and elsewhere; fairly endangered in California) (Attachment 2: Photograph 9). Decumbent goldenbush was observed in the Artemisia californica–Eriogonum fasciculatum– Malosma laurina Association (Diegan coastal sage scrub).
4.7.2 Sensitive Invertebrates
No sensitive invertebrate species were identified in the survey area.
4.7.3 Sensitive Reptiles
Two sensitive reptile species were identified in the survey area. These species are discussed below.
Coastal whiptail (Aspidoscelis tigris stejneri). The coastal whiptail is an RMP species to be monitored. It is often found in a variety of habitats such as chaparral, woodland, and riparian areas. These habitats consist primarily of hot and dry open areas with sparse foliage (California Herps 2014). This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
Coastal rosy boa (Lichanura trivirgata roseofusca). The coastal rosy boa is an RMP species to be monitored (Attachment 2: Photograph 10). It is often associated with arid scrublands, semi-arid shrublands, rocky deserts, canyons, and other rocky areas. Coastal rosy boa appears to be associated with riparian areas, but does not require permanent water (California Herps 2014). This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
Page 20 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
4.7.4 Sensitive Birds
Five sensitive avian species were identified in the survey area. These species are listed and discussed below.
Grasshopper sparrow (Ammodramus savannarum perpallidus). This species is a CDFW species of special concern and an RMP species to be monitored. This species’ ideal habitat is native grassland, but it also uses non-native grasslands and other habitats, such as salt marshes and alkaline meadows dominated by saltgrass (Distichlis sp.). It prefers larger tracts of habitat composed of short to middle-high moderately open grasslands (Shuford and Gardali 2008). Additionally, their habitat typically includes shrubs, common in coastal sage scrub, and may be shrubby enough to be classified as coastal sage scrub (Unitt 2004). This species was observed in the Artemisia californica– Eriogonum fasciculatum–Malosma laurina Association (Diegan coastal sage scrub).
Southern California rufous-crowned sparrow (Aimophila ruficeps canescens). This species is a CDFW watch list species, an RMP species to be monitored, and an MSCP covered species. Southern California rufous-crowned sparrows are found in sage scrub, broken or burned chaparral habitats, and grasslands with scattered shrubs. The species exhibits a strong preference for moderate to steep, south-facing, dry, rocky slopes with a 50 percent cover of low shrubs (Unitt 2004; Collins 1999). This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
Red-tailed hawk (Buteo jamaicensis). This species is an RMP species to be monitored. The red-tailed hawk typically nests in western sycamore (Platanus racemosa), coast live oak (Quercus agrifolia), and gum tree (Eucalyptus spp.) groves and is a common resident of San Diego County. This species was observed flying over and foraging within the survey area. The native trees located outside of the Proctor Valley (South) parcel provide suitable nesting habitat for the red-tailed hawk; however, trees are not present within the parcel for nesting on-site. This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
California horned lark (Eremophila alpestris actia). This species is a CDFW watch list species and an RMP species to be monitored. This coastal subspecies’ year-round range is fragmented in San Diego County and includes the coastal strand, arid grasslands, and sandy desert floors in Anza–Borrego Desert (Unitt 2004). Plowed fields, graded lands, and other disturbed areas attract the California horned lark. California horned larks are typically not found in chaparral (Unitt 2004; Zeiner et al. 1988–1990). This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
Page 21 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
American kestrel (Falco sparverius). This species is an RMP species to be monitored. Ideal breeding habitat for this resident species includes tall western sycamore or oak trees (Quercus sp.) adjacent to grassland or open ground where birds can forage. This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub).
4.7.5 Sensitive Mammals
Two sensitive mammal species were identified in the Proctor Valley (South) parcel. These species are discussed below.
Black-tailed jackrabbit (Lepus californicus bennettii). This species is a CDFW Species of Special Concern and an RMP species to be monitored. This species typically occupies open or semi-open habitats, such as coastal sage scrub and open chaparral areas, which are available to the jackrabbit in the survey area. Preferred foraging habitat includes areas with ample grasses and forbs, which are commonly found within the survey area. This species was observed in the Bahiopsis laciniata–Artemisia californica– Eriogonum fasciculatum Association (Diegan coastal sage scrub) and Artemisia californica–Eriogonum fasciculatum–Malosma laurina Association (Diegan coastal sage scrub).
Southern mule deer (Odocoileus hemionus fuliginata). This species is an MSCP covered species. Signs of mule deer occurrence, such as tracks or droppings, were observed throughout the survey area. This species requires relatively large, undisturbed tracts of chaparral, coastal sage scrub, and mixed grassland/shrub habitats, which are available to the mule deer within the survey area. This species was observed in the Bahiopsis laciniata–Artemisia californica–Eriogonum fasciculatum Association (Diegan coastal sage scrub) and Malosma laurina–Lotus scoparius Association (coastal scrub).
4.8 Invasive Exotic Plant Species
Twenty-one non-native plant species were documented in the Proctor Valley (South) parcel. Under the California Invasive Plant Inventory Database established by Cal-IPC (2014), non-native weed species are ranked according to ecological impacts, invasive potential, and distribution. Fourteen of the twenty-one non-native species that occur within the Proctor Valley (South) parcel have been evaluated and ranked by Cal-IPC. Invasive species are listed in Attachment 7.
4.8.1 Cal-IPC High
Non-native weed species ranked as ‘high’ have severe ecological impacts, moderate to high rates of dispersal and establishment, and are widely distributed. One plant species
Page 22 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
documented in the Proctor Valley (South) parcel is ranked as ‘high’ under the California Invasive Plant Inventory Database. This species is discussed below.
Red brome (Bromus madritensis ssp. rubens). This species is an exotic annual grass that is spreading into coastal scrub, desert shrubland, three-needle pine woodlands, and pinyon pine–juniper communities. Increased fire frequency favors red brome establishment by reducing competition from native species and converts these communities to annual grasslands (DiTomaso et al. 2007). Sparse populations of red brome were identified in all of the vegetation communities within the Proctor Valley (South) parcel.
4.8.2 Cal-IPC Moderate
Non-native weed species ranked as ‘moderate’ have substantial, but generally not severe, ecological impacts; moderate to high rates of dispersal and establishment; and limited- to wide-spread distribution. In general, successful establishment of weed species ranked as ‘moderate’ is dependent upon ecological disturbance. Seven plant species documented in the Proctor Valley (South) parcel are ranked as ‘moderate’ under the California Invasive Plant Inventory Database. Species ranked as moderate by Cal-IPC and that occur within the Proctor Valley (South) parcel are listed in Attachment 7.
4.8.3 Cal-IPC Limited
Non-native weed species ranked as ‘limited’ have minor ecological impacts, moderate to low rates of dispersal and establishment, and generally limited distribution. However, these species are still considered invasive and can be both persistent and locally problematic. Six plant species documented in the Proctor Valley (South) parcel are ranked as ‘limited’ under the California Invasive Plant Inventory Database. Species ranked as limited by Cal-IPC and that occur within the Proctor Valley (South) parcel are listed in Attachment 7.
5.0 Discussion/Recommendations
5.1 Wildlife Movement Corridor
Within the Proctor Valley (South) parcel, wildlife can move unrestricted throughout the site. The Proctor Valley (South) parcel is not fenced, allowing wildlife to move freely. No barriers to wildlife movement occur to the north, east, south, or west within the Proctor Valley (South) parcel. Distant potential barriers to wildlife movement at the Proctor
Page 23 2014 Baseline Survey Report for Otay Ranch Preserve—Proctor Valley (South) Parcel
Valley (South) parcel include Proctor Valley Road to the west and north, Campo Road to the east, and Otay Lakes Road to the south.
5.2 Trespassing
The Proctor Valley (South) parcel is located in a remote part of the Jamul Mountains. There are two dirt roads on-site that are becoming overgrown with vegetation; one is located at the toe of the slope in the southwest corner of the parcel and the other is located along the ridgeline near the northern edge of the parcel. Signs of trespassing were not apparent during the baseline surveys.
5.3 Focused Surveys
The following focused surveys are recommended due to the presence of suitable habitat: (1) focused sensitive plant surveys; (2) coastal California gnatcatcher surveys; and (3) Quino checkerspot butterfly surveys.
