DESCRIPTION OF THE BIOTIC RESOURCES A Vegetation and Wildlife Resources 1. Vegetation Vegetation within the study area includes English ivy and an introduced bamboo plant growing ' on the existing seawall Ruderal vegetation, including non-native grasses and weedy herbaceous species, dominates the area adjacent to the project study area Non-native grasses include Annual ryegrass, Bermuda grass, Ripgut brome, and Vulpia (scientific names are presented in Exhibit 5) Weedy herbaceous species include Bristly ox-tongue, Prickly tlettuce, Russian thistle, Pineapple weed, and Yellow star-thistle Three introduced Bottle trees are located on the north side and adjacent to the existing seawall in the center of the project study area (Figure 2) One Zelkova tree and several Tree- of-heaven trees occur along the existing seawall on the south side of the gas station Introduced bamboo plants have become established in the abandoned lot adjacent to the ' seawall Lists of plant species observed in and adjacent to the protect study area are presented in Exhibit 5 ' 2. Wildlife Species richness and diversity is extremely low in heavily developed downtown, urban habitats (Mayer and Laudenslayer, 1988) Wildlife species commonly associated with heavily developed downtown areas include House sparrow, European starling, and Rock dove The presence of the Stockton Channel and some open, ruderal habitat provides foraging habitat for additional wildlife species Mammal species that could occur in an urban setting include House mouse, Brown rat, and Black rat ' Wildlife observed during surveys in the protect study area included avian species such as American crow, House sparrow, and European starling Double-crested cormorant, Mallard, ' Western grebe, and Western sandpiper were observed in the Stockton Channel adjacent to the study area An American kestrel was observed foraging in the abandoned parking lot north of the project study area No amphibian, reptile, or mammal species were observed A list of wildlife species observed in and adjacent to the project study area is presented in ' Exhibit 5 along with their scientific names No raptor nests were observed in or near the project study area Barn swallows were nesting ' under the Center Street Bridge and foraging in the Stockton Channel adjacent to the study area, but were not nesting under any structures in the study area There was no evidence that bats roosted anywhere within the project study area ' B. Description of Special-Status Species Evaluated CNDDB/ RareFind records (Exhibit 2) and information received from the Service (Exhibit 3) ' were used to compile a list of special-status species that could potentially occur in the project study area (Exhibit 4) Site surveys were then conducted to determine if suitable habitat for these species and/or individuals of these species were present in the project study area ' Special-status species for which suitable habitat is not present in the protect study area, or whose distributional limits preclude the possibility of their occurrence in the project study area are listed in Exhibit 4, but are not described further Special-status species for which marginal SEA_Eioa ooc 9/18197 Sycamore Environmental ConsullanlS Inc 6 II ,
