f Biological Resources, MONK &?ASSOCIATES Impacts and Mitigations Tracy Facility Expansion Site Showy madia(Madia radiata)is on CNPS List 1B. It has no State or Federal status. This showy member of the sunflower family is found in cismontane woodland or grassland habitats where it flowers.between March and May. The project site's grassland habitat provides potentially suitable habitat for this species,therefore,its presence cannot be ruled out without cZ4ucting appropriately time surveys. Caper-fruited tropidocarpum(Tropidocarpum capparideum) is a Federal species of concern and is on CLAPS List 1A. It has no State status. This plant has not been observed since 1957 and is presumed extinct. However, since it was known to occur in'grassland habitats where it bloomed between March and April, an attempt to rediscover this plant species will be made at the time that surveys for the other special-status plant species are conducted. 11.2 Special-Status Animals CNDDB (RareFind 2 application) has records for 10 special-status animal species occurring within 10 miles of the project site. Additionally,M&A reviewed other documents prepared for projects in the region and found an additional five species that should be considered during this environmental review. These 15 species are listed in Table 5 along with their habitat affinities and legal status, and are discussed below. Vernal pool fairy shrimp (Branchinecta lynchr) is federally listed as threatened. It has no State status. This fairy shrimp is found in vernal pool habitats of the Central Valley, central coast mountains, and south coast mountains(Eng et al. 1990). It has been most commonly observed in vernal pools with clear to tea-colored water, in grass or mud bottomed swales,earth sumps,or basalt flow depression pools in unplowed grasslands. One population has also been observedin sandstone rock outcrops and another population in alkaline vernal pools(USFWS 1994). The vernal pool fairy shrimp has been collected from early December to early May. It has not been I found in flowing waters(USFWS, 1992). In San Joaquin County there are known populations of vernal pool fairy shrimp within ephemeral pool environments (CIIN, 1995). There are no vernal pool environments(isolated wetlands)on the project site. The only aquatic habitat found within the project site is Corral Hollow Creek. This creek is an ephemeral creek that is known to have high flows during wet winters. Vernal pool fairy shrimp are not known to occur in flowing waters and therefore are not likely to occur within the project site. Therefore, no impacts to vernal pool fairy shrimp are expected from the proposed project. Western spadefoot toad(Scaphiopus hammondi hammondt)is a Federal"species of concern,". and a California"species of special concern." It is also a State designated"protected.amphibian." This toad occurs throughout the Central Valley and adjacent foothills(Zeiner et al., 1988). This toad frequents washes, floodplains of rivers, alluvial fans,playas, and alkali flats,but also ranges into the mountains(Stebbins 1985). Grasslands with shallow temporary pools for breeding are optimal habitats for this species(Zeiner et al. 1988). its larvae have also been identified in stock ponds (pers.obs.). Since the western spadefoot spends approximately 80 percent of its life below e a necessary habitat component for this species. Using the"spade,,on the ground,friable soils are ary p sp g sp underside of its foot,the spadefoot will burrow its way into the friable soil,where it will remain until it is time to breed. It becomes active following relatively warm(>10.0-12.8 degrees C)rains 15 I
