Setting a. Methods. The methods used to evaluate the site and project are identified below. (1) Records Search and Literature Review. Available reports of biological resources at the project site and special-status species databases were reviewed to identify habitat types and species potentially occurring at the project site. Reports that were prepared by Sycamore Associates, LLC and reviewed by LSA include: Rare Plant Surveys and Habitat Assessment for Wetlands at the Seeno Benicia Industrial Park Project, City of Benicia, Solano County, California1; Rare Plant Surveys of Upland Habitats, Seeno Benicia Industrial Park Project, City of Benicia, Solano County, California2; Summer-Season Focused Special-status Plant Surveys at the Proposed Benicia Industrial Park, Solano County3; Bat Habitat Assessment, Benicia Business Park, Solano County, California4; and Verified Wetlands Delineation and Jurisdictional Determination for the Seeno Benicia Industrial Park Project, City of Benicia, Solano County, California5. The Benicia Business Park Bat Roost Reconnaissance Survey that was prepared by Wetland Research Associates (WRA) was also reviewed. 6 The California Natural Diversity Database7 (CNDDB) and the California Native Plant Society’s (CNPS) on-line Inventory of Rare and Endangered Plants8 were searched to identify potentially occurring special-status species.

HARRISON2 1 USDA-Forest Service, Paci®c Southwest Region, 1323 Club Drive, Vallejo, CA 94592 [email protected] 2 Department of Environmental Science and Policy, University of California, Davis, CA 95616 3 Information Center for the Environment, DESP, University of California, Davis, CA 95616 ABSTRACT We present a summary of a database documenting levels of af®nity to ultrama®c (``serpentine'') sub- strates for taxa in the California ¯ora, USA. We constructed our database through an extensive literature search, expert opinion, ®eld observations, and intensive use of accession records at key herbaria. We developed a semi-quantitative methodology for determining levels of serpentine af®nity (strictly endemic, broadly endemic, strong ``indicator'', etc.) in the California ¯ora. In this contribution, we provide a list of taxa having high af®nity to ultrama®c/serpentine substrates in California, and present information on rarity, geographic distribution, taxonomy, and lifeform. Of species endemic to California, 12.5% are restricted to ultrama®c substrates. Most of these taxa come from a half-dozen plant families, and from only one or two genera within each family. The North Coast and Klamath Ranges support more serpentine endemics than the rest of the State combined. 15% of all plant taxa listed as threatened or endangered in California show some degree of association with ultrama®c substrates. Information in our database should prove valuable to efforts in ecology, ¯oristics, biosystematics, conservation, and land management.
