L <br />Field Survey. Jones & Stokes Associates conducted surveys for San Joaquin kit foxes during <br />February 2-15, 1993, using the USFWS survey protocol in effect at that time. (See "San Joaquin <br />Kit Fox" below and Appendix A for survey details.) In addition, a Jones & Stokes Associates <br />biologist conducted a reconnaissance -level survey on August 20, 1993. No San Joaquin kit foxes <br />or their sign (scats, tracks, or prey remains) were observed during either field survey. <br />During field surreys, five special -status species were observed in the project area: loggerhead <br />shrike, California horned lark, ferruginous hawk, northern harrier, and black -shouldered kite. <br />Although not observed at the project site during field surveys, the annual grasslands provide <br />suitable foraging habitat for the Swainson's hawk, mountain plover, and tricolored blackbird and <br />suitable nesting and foraging habitat for burrowing owls. <br />Information on the distribution, habitat association, and status in the project area is presented <br />below for the species observed or likely to occur at the project site. <br />San Joaquin Kit Fox <br />Background. The San Joaquin kit fox is particularly uncommon in the northern portion of its range in <br />Contra Costa, Alameda, and San Joaquin Counties, where it is apparently restricted to a few small <br />remnant populations (Orloff et al. 1986, Jones & Stokes Associates 1989, San Joaquin County Community <br />Development Department 1993). <br />The San Joaquin kit fox inhabits and grasslands and alkali sinks (U.S. Fish and Wildlife Service 1983). <br />In the northern portion of its range, the kit fox occurs primarily in foothill grasslands (Orloff et al. 1986). <br />Kit foxes typically avoid dense oak woodlands and agricultural lands (U.S. Fish and Wildlife Service 1983). <br />Kit foxes are mostly nocturnal and feed primarily on small mammals, including kangaroo rats, black -tailed <br />hares, desert cottontails, and California ground squirrels. Kit foxes use burrows for resting, cover, and <br />breeding. In the northern portion of their range kit foxes frequently use burrows built by other animals, <br />especially ground squirrels (Orloff et al. 1986). <br />San Joaquin kit foxes change den sites frequently, moving most often in summer and less often in winter <br />and spring (Morrell 1972). <br />The San Joaquin kit fox population has declined primarily because of habitat loss. Most of the preferred <br />valley bottom grassland habitats in the northern range has been eliminated by agricultural, urban, <br />industrial, and mineral development (U.S. Fish and Wildlife Service 1983). <br />Ongoing Kit Fox Conservation Planning Efforts in San Joaquin County. The San Joaquin County <br />Community Development Department has published a preliminary draft habitat conservation plan (HCP) <br />for the San Joaquin kit fox in western San Joaquin County (San Joaquin County Community Development <br />Department 1993). The principal goal of the HCP is to create a legal, planning, and management <br />framework that ensures that San Joaquin County, the local agency controlling land use in the study area, <br />will exercise its authority to avoid jeopardizing the continued existence of the San Joaquin kit fox currently <br />occupying the western portion of San Joaquin County and adjacent areas. The proposed project site is <br />located approximately 0.5 mile east of the Delta -Mendota Canal, which is the eastern boundary of the HCP <br />study area and its proposed jurisdictional boundary. <br />Historical and recent records of the San Joaquin kit fox reported in the HCP are shown in Figure 4.2.1. <br />There are 10 historical records within 3 miles of the project site. EIP Associates conducted kit fox surveys <br />for the HCP and reported three confirmed kit fox sightings, three records of kit fox tracks, and two records <br />of photographs of kit fox within 1-3 miles of the project site (San Joaquin County Community Development <br />Department 1993). <br />ER -93-1 -37- (9-27-93) <br />
