AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY 12956 DUDEK 30 April 2022 Wildlife Twenty-seven wildlife species or their sign were observed during the April 2021 field reconnaissance: Sierran treefrog (Pseudacris sierra), western fence lizard (Sceloporus occidentalis), band-tailed pigeon (Patagioenas fasciata), white-throated swift (Aeronautes saxatilis), Anna’s hummingbird (Calypte anna), turkey vulture (Cathartes aura), acorn woodpecker (Melanerpes formicivorus), hairy woodpecker (Dryobates villosus), Cassin’s vireo (Vireo cassinii), Steller’s jay (Cyanocitta stelleri), California scrub-jay (Aphelocoma californica), chestnut-backed chickadee (Baeolophus inornatus), violet-green swallow (Tachycineta thalassina), bushtit (Psaltriparus minimus), wrentit (Chamaea fasciata), white-breasted nuthatch (Sitta carolinensis), house wren (Troglodytes aedon), Bewick’s wren (Thryomanes bewickii), American robin (Turdus migratorius), purple finch (Haemorhous purpureus), dark-eyed junco (Junco hyemalis), golden-crowned sparrow (Zonotrichia atricapilla), spotted towhee (Pipilo maculatus), orange- crowned warbler (Leiothlypis celata), yellow-rumped warbler (Setophaga coronata), Wilson’s warbler (Cardellina pusilla), and black-headed grosbeak (Pheucticus melanocephalus). The project site provides high-quality habitat for many other native wildlife species. Common amphibians or reptiles likely to occur, in addition to Sierran treefrog and western fence lizard, include arboreal salamander (Aneides lugubris), California slender salamander (Batrachoseps attenuatus), southern alligator lizard (Elgaria multicarinata), and common gartersnake (Thamnophis sirtalis). Mammal species expected to occur include black-tailed deer (Odocoileus hemionus), Virginia opossum (Didelphis virginiana), coyote (Canis latrans), striped skunk (Mephitis mephitis), and gray squirrel (Sciurus griseus). Special-Status and/or Regulated Resources Special-Status Plants Based on the results of the literature review and April 2021 field reconnaissance, 26 special-status plant species were identified as occurring or potentially occurring in the project vicinity. Of these, 22 species were removed from consideration and are not expected to occur due to the lack of suitable habitat within or adjacent to the project site, or the project site being outside of the species’ known elevation range. The remaining four species have moderate potential to occur based on the presence of woodland and scrub habitat, as summarized in Table 3.4-1. No special-status plants were identified during the April 2021 field reconnaissance, but a formal botanical inventory was not conducted.
