Planning and Natural Resources Committee R-19
PLANNING AND NATURAL RESOURCES COMMITTEE R-19-140 October 22, 2019 AGENDA ITEM 2 AGENDA ITEM Addendum to the Mindego Hill Ranch Grazing Management Plan to Expand Conservation Grazing into the South Pasture GENERAL MANAGER’S RECOMMENDATION Forward a recommendation to the Board of Directors to adopt an addendum to the Mindego Hill Ranch Grazing Management Plan as an amendment to the Russian Ridge Use and Management Plan that adds the south pasture as part of the conservation grazing area on the property. SUMMARY The General Manager recommends adoption of an addendum to the Mindego Hill Ranch (Mindego) Grazing Management Plan (Grazing Plan) (Attachment 1) to expand the conservation grazing area within Russian Ridge Open Space Preserve (Russian Ridge). The addendum identifies the existing resources and current uses in the proposed south pasture expansion area, and provides recommendations for future improvements, management, and monitoring at the site. The recommendations include: installation of additional water infrastructure, updates to fencing, management of brush encroachment into grasslands, and monitoring of resource management activities. Midpeninsula Regional Open Space District (District) staff and the current grazing tenant have been working with the Natural Resources Conservation Service (NRCS) to secure cost-sharing support for the anticipated improvements. Implementation of the recommended infrastructure improvements is estimated to cost $119,341, of which approximately $85,000 is projected to be the District’s share with the remainder funded by the NRCS. Recommended improvements would span four years with work anticipated to begin in July 2020. If approved, the District’s share would be allocated across the next four fiscal years and requested as part of the annual Budget and Action Plan development process. -

It’s the reason we call our region the WBay Area. It shapes the Peninsula and sculpts the land. It cleans the air. It comes down from the sky as rain and fog, and comes up from the earth via springs and aquifers. It makes up more than 70 percent of most living things.

San Mateo County
Steelhead/rainbow trout resources of San Mateo County San Pedro San Pedro Creek flows northwesterly, entering the Pacific Ocean at Pacifica State Beach. It drains a watershed about eight square miles in area. The upper portions of the drainage contain springs (feeding the south and middle forks) that produce perennial flow in the creek. Documents with information regarding steelhead in the San Pedro Creek watershed may refer to the North Fork San Pedro Creek and the Sanchez Fork. For purposes of this report, these tributaries are considered as part of the mainstem. A 1912 letter regarding San Mateo County streams indicates that San Pedro Creek was stocked. A fishway also is noted on the creek (Smith 1912). Titus et al. (in prep.) note DFG records of steelhead spawning in the creek in 1941. In 1968, DFG staff estimated that the San Pedro Creek steelhead run consisted of 100 individuals (Wood 1968). A 1973 stream survey report notes, “Spawning habitat is a limiting factor for steelhead” (DFG 1973a, p. 2). The report called the steelhead resources of San Pedro Creek “viable and important” but cited passage at culverts, summer water diversion, and urbanization effects on the stream channel and watershed hydrology as placing “the long-term survival of the steelhead resource in question”(DFG 1973a, p. 5). The lower portions of San Pedro Creek were surveyed during the spring and summer of 1989. Three O. mykiss year classes were observed during the study throughout the lower creek. Researchers noticed “a marked exodus from the lower creek during the late summer” of yearling and age 2+ individuals, many of which showed “typical smolt characteristics” (Sullivan 1990). -
Historical Status of Coho Salmon in Streams of the Urbanized San Francisco Estuary, California
CALIFORNIA FISH AND GAME California Fish and Game 91(4):219-254 2005 HISTORICAL STATUS OF COHO SALMON IN STREAMS OF THE URBANIZED SAN FRANCISCO ESTUARY, CALIFORNIA ROBERT A. LEIDY1 U. S. Environmental Protection Agency 75 Hawthorne Street San Francisco, CA 94105 [email protected] and GORDON BECKER Center for Ecosystem Management and Restoration 4179 Piedmont Avenue, Suite 325 Oakland, CA 94611 [email protected] and BRETT N. HARVEY Graduate Group in Ecology University of California Davis, CA 95616 1Corresponding author ABSTRACT The historical status of coho salmon, Oncorhynchus kisutch, was assessed in 65 watersheds surrounding the San Francisco Estuary, California. We reviewed published literature, unpublished reports, field notes, and specimens housed at museum and university collections and public agency files. In watersheds for which we found historical information for the occurrence of coho salmon, we developed a matrix of five environmental indicators to assess the probability that a stream supported habitat suitable for coho salmon. We found evidence that at least 4 of 65 Estuary watersheds (6%) historically supported coho salmon. A minimum of an additional 11 watersheds (17%) may also have supported coho salmon, but evidence is inconclusive. Coho salmon were last documented from an Estuary stream in the early-to-mid 1980s. Although broadly distributed, the environmental characteristics of streams known historically to contain coho salmon shared several characteristics. In the Estuary, coho salmon typically were members of three-to-six species assemblages of native fishes, including Pacific lamprey, Lampetra tridentata, steelhead, Oncorhynchus mykiss, California roach, Lavinia symmetricus, juvenile Sacramento sucker, Catostomus occidentalis, threespine stickleback, Gasterosteus aculeatus, riffle sculpin, Cottus gulosus, prickly sculpin, Cottus asper, and/or tidewater goby, Eucyclogobius newberryi. -
