03 Public Advisory Committee of the Santa Clara Valley Habitat Agency Agenda: May 2, 2019 Item No.:03 TO: Public Advisory Committee FROM: Terah Donovan, Principal Program Manager SUBJECT: Santa Clara Valley Habitat Plan FY1718 Annual Report RECOMMENDED ACTION: Receive presentation and review the Santa Clara Valley Habitat Plan FY1718 Annual Report. BACKGROUND: The Habitat Agency prepares an annual report to document Habitat Plan permit compliance, covered activity impacts, conservation, management, restoration/creation actions, and monitoring results. The annual report summarizes the previous fiscal year’s implementation activities (July 1 to June 30). Annual reports are submitted to the Implementation Board for review and approval. They also are submitted to the Wildlife Agencies, other interested parties, such as the U.S. Army Corps of Engineers and California State and Regional Water Quality Boards, and made available to the public and posted on the Habitat Plan website. This fourth annual report summarizes fiscal year 2017-2018, year 5 of 50 of Habitat Plan implementation. Covered Activities A total of 226 projects have received take coverage under the Habitat Plan since permit issuance. Cumulative land cover impacts total 1,858 acres of permanent and 331 acres of temporary. Stream impacts total 182 feet of permanent and 737 feet of temporary. Of the 226 projects, 128 were private, 82 were public, and 16 were Participating Special Entity (PSE) projects. Covered activity types include 125 urban development projects, 9 in-stream operations and maintenance activities, 8 in-stream capital projects, 30 rural operations and maintenance projects, 29 rural development projects, 16 rural capital projects, and 9 conservation strategy implementation projects. Most project impacts occurred in developed (41%) and agricultural areas (38%), with a minority occurring in natural lands (21%). The reporting period saw the most projects permitted in a reporting year with 61 projects receiving take coverage: 41 private projects, 18 public projects, and 2 PSE projects. The covered projects consisted of 38 urban development projects, 1 in-stream operation and maintenance activity, 2 in- stream capital projects, 7 rural operations and maintenance projects, 4 rural development projects, 5 rural capital projects, and 4 conservation strategy implementation projects. The 61 projects resulted in 488 acres of permanent impacts and 78 acres of temporary impacts on land cover. Similar to overall trends, most project impacts occurred in developed (47%) areas; however, agricultural and natural lands impacts were nearly the same at 26% and 27% respectively. 11 03 Public Advisory Committee of the Santa Clara Valley Habitat Agency Agenda: May 2, 2019 Item No.:03 Land Acquisition The Habitat Agency has 2,787 acres under protection or management. The Reserve System totals 1,867 acres with over 5% of the conservation target being achieved. An additional 920 acres are under management agreements for western burrowing owl. The Reserve System includes 14 land cover types and nearly 14 miles of stream. Rare serpentine bunchgrass grassland as the most prevalent (1,237 acres). The Reserve System fulfills over 30% of the modeled habitat protection goals for six of these covered species—Bay checkerspot butterfly, Mount Hamilton thistle, fragrant fritillary, smooth lessingia, Metcalf Canyon jewelflower, and most beautiful jewelflower. Occurrences of Mount Hamilton thistle, Santa Clara Valley dudleya, fragrant fritillary, Loma Prieta hoita, Metcalf Canyon jewelflower, and most beautiful jewelflower are protected. The Reserve System contributes to the protection of four landscape linkages, two on the Coyote Ridge Open Space Preserve (#6, #7) and two on the Pacheco Creek Reserve (#15 and #17). No new land was enrolled into the Reserve System during the reporting period. Reserve System Management The Habitat Agency manages two Reserve System properties—the Coyote Ridge Open Space Preserve and Pacheco Creek Reserve. Treatment of invasive plant species, conservation grazing to achieve residual dry matter (RDM) targets, basic road improvements, a cultural resources inventory, seed collection, and a property boundary survey were completed at the Coyote Ridge Open Space Preserve. The Habitat Agency completed the Coyote Ridge Open Space Preserve Management and Monitoring Plan, which provides a detailed prescription for the long-term management and monitoring. Management actions performed on the Pacheco Creek Reserve included maintenance activities, such as installing solar powered well pumps, small fencing repairs, signage, weed control, and trash removal. The Habitat Agency began the Pacheco Creek restoration planning process to improve creek conditions on the Reserve. Western Burrowing Owl Management The Habitat Agency manages two of five western burrow owl breeding sites and conducts surveys throughout the Permit Area and Extended Permit Area for burrowing owl conservation. The 2018 western burrowing owl surveys documented 52–53 breeding adult burrowing owls and 80–81 documented fledged young across the five breeding sites. This is a decrease in the number of adults present during the breeding season between previous reporting year (74 individuals) to current reporting year; however, the number of adults at the San José-Santa Clara Regional Wastewater Facility was the highest recorded, with 18 adults observed. Management agreements with the San José-Santa Clara Regional Wastewater Facility and the Don Edwards San Francisco National Wildlife Refuge include 920 acres of burrowing owl breeding habitat, approximately 17% of the total required under the Habitat Plan. Three burrowing owl studies were also conducted in the reporting year. Members of the burrowing owl research team visited colleagues in British Columbia to observe captive breeding facilities to prepare for future Tier 3 recovery actions. 12 03 Public Advisory Committee of the Santa Clara Valley Habitat Agency Agenda: May 2, 2019 Item No.:03 Habitat Restoration and Creation Eight restoration and creation projects are completed, on-going, or in the planning phases. Projects restored nearly 5 acres of riparian woodlands, 4.5 acres of perennial and seasonal wetlands and ponds, and 1.83 miles of streams. They benefitted 5 of 18 covered species—California red-legged frog, California tiger salamander, western pond turtle, Mount Hamilton thistle, and Coyote ceanothus. One project improved a regional connection between the Diablo Range and Santa Cruz Mountains. Restoration projects span the Alamitos, Coyote, Pacheco, and Pajaro Watersheds. Two restoration projects were initiated during the report period and are now complete—the San Felipe Creek Restoration Project on Joseph D. Grant County Park and the Pacheco Creek Riparian Planting Project on the Pacheco Creek Reserve. These projects demonstrate the on-going success of partnerships with Santa Clara County Parks and Pt. Blue’s Student and Teachers Restoring a Watershed program. The Coyote Ceanothus Population Creation Project, implemented by the Santa Clara Valley Water District, completed the successful remediation of the Phytophthora plant pathogen. Monitoring, Research, and Adaptive Management Monitoring activities occurred within and outside the Reserve System to document status and trends of covered species, inform management, and provide baseline information. On the Coyote Ridge Open Space Preserve, surveys revealed a third year of decline of Bay checkerspot butterfly; however, this is within normal historic variability. Habitat for the species continues to persist and additional cattle could be supported as part of the grazing program. The number of fragrant fritillary and Loma Prieta hoita, two covered species, increased. Pacheco Creek Reserve mapping identified seven land cover types, including over 8 acres of Central California sycamore alluvial woodland, which is locally rare. Monitoring of the two known locations of Tiburon Paintbrush, a covered plant, was conducted to document the effectiveness of seeding efforts to recovery the species. Surveys confirmed that seeding of the population is effective to increase the population size and provided recommendation for management of both populations, one on Kirby Canyon landfill property, and the other on Santa Clara Valley Water District property. Research from three California Department of Fish and Wildlife Local Assistance Grant program projects was completed--Wintering Burrowing Owl Monitoring, Evaluating Threats Posed by Exotic Phytophthora Species to Endangered Coyote Ceanothus and Selected Natural Communities in the Habitat Plan Area, and Modeling Climate Change Effects on Pond Hydroperiods in the Coyote Valley— and will inform Habitat Plan implementation. This program has funded 13 projects through the reporting year. Stay-Ahead Provision Stay-Ahead requirements were met for 11 of 17 resources protected within the Reserve System or restored by the Habitat Agency. The Habitat Agency continues to work in good faith with the Wildlife Agencies and Co-Permittees to comply with the Stay-Ahead provision. Enrollment of the Calero conservation easement area will result in compliance for grasslands, oak woodlands, riparian forest 13 03 Public Advisory Committee of the Santa Clara Valley Habitat Agency Agenda: May 2, 2019 Item No.:03 and scrub, and most beautiful jewelflower1. Wetland compliance is likely to occur with the implementation of the planned restoration projects and the same enrollment. The Santa Clara
