MOUNTAIN HOUSE NEIGHBORHOODS KAND L INITIAL STUDY 5.ENVIRONMENTAL CHECKLIST 4.BIOLOGICAL RESOURCES LS (Mus musculus, Reithrodontomys megalotis, and Peromyscus maniculatus)and voles(Microtus californicus)are also likely occur in the project area. Based on habitat types present,a number of amphibians and reptiles are also expected to occur in the area. Special-Status Species For the purpose of this assessment, special-status species are those plants and animals listed, proposed for listing, or candidates for listing as threatened or ' endangered by the U.S. Fish and Wildlife Service(USFWS)or the National Marine Fisheries Service(NMFS);those listed or proposed for listing as rare, threatened, or endangered by the CDFG; plants occurring on lists 1 B or 2 of the California Native Plant Society's Inventory of Rare and Endangered Plants of California, (2001 and electronic edition update); and animals designated as "Species of Special Concern"by the CDFG. (` Plant Species �—] A list of special-status plants evaluated for their potential to occur in the project site is presented in Table D-1 in Appendix D. This list was compiled through review of previous reports prepared for the Mountain House project area, a query F�, of the CNDDB (CDFG,2011),the California Native Plant Society(CNPS) Inventory of Rare and Endangered Vascular Plants of California(CNPS,2001 and electronic edition update), and the biological assessments prepared for the _, site(Moore Biological Consultants, 2010a and 2010b). The CNDDB query included occurrences within a 5-mile radius of the project site. lFifteen species of special-status plants were evaluated for their potential to occur in the project area(Table D-1). Of these species,only two, rose mallow i (Hibiscus lasiocarpus)and Mason's lilaeopsis(Lilaeopsis masonil),were I identified as having the potential to occur in the project area, along suitable ` aquatic habitat that borders the site. Potentially suitable habitat for Mason's lilaeopsis and rose mallow exists in some of the wetland areas associated with Old River, and Mason's lilaeopsis has been located along Old River in the Mountain House project area in the past(Baseline Environmental Consulting. 1994). However, neither Mason's lilaeopsis nor rose mallow was observed during focused surveys conducted by North Fork Associates in 2003 along the portion of Old River that abuts Neighborhoods K and L. No other special-status plants were observed within Neighborhoods K and L during the most recent . surveys of the SPIT area conducted in 2004,or the subsequent surveys conducted in 2010. Wildlife Species +, Special-status wildlife species with the potential to occur in the project area were also identified through review of previous documents and a search of the CNDDB(CDFG,2011). The species evaluated are listed in Table D-1. Swainson's hawk(Buteo swainsonr) and California burrowing owl(Achene cunicularra) have been reported to occur in the project area, and sensitive fish i [ have been observed or are known to occur in habitats associated with Old River.
