City of Pleasanton—Hidden Canyon Residences and Preserve Draft EIR Biological Resources FirstCarbon Solutions 3.3-7 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-03 Bio Resources.docx hyssop loosestrife (Lythrum hyssopifolia), scarlet pimpernel (Lysimachia arvensis), and rabbits foot grass. Prominent redoximorphic features were evident in the soil profile, indicating hydric soils. Wetlands hydrology indicators included the presence of reduced iron, drainage patterns, and saturation visible on aerial imagery. The source of hydrology for one of the seasonal wetlands is a drainage that occurs off-site to the west on the adjacent property. Water from the adjacent property enters the project site within a swale that lacks a defined bed and bank. These waters percolate into the soils on the site and within a low depression along the shoulder of Dublin Canyon Road, adjacent to the site’s northern boundary. Because these seasonal wetlands were dominated by non-native vegetation and only appear to be inundated immediately following heavy storm events, these features would not be expected to provide high habitat value for native wildlife over and above that of surrounding annual grassland habitats. The species expected to occur in this habitat would be similar to those occurring in the surrounding upland habitats. Wildlife Amphibians On-site drainages that convey water provide a seasonal source of drinking water for species occurring in surrounding habitats and, when wet, also provide breeding habitat for Pacific treefrogs (Hyla regilla) and potential movement habitat for California red-legged frogs (Rana draytonii). Leaf litter and decaying logs provide a moist microclimate suitable for additional amphibians such slender salamander (Batrachoseps mexicana), arboreal salamander (Aneides lugubris), and California newt (Taricha torosa). A comprehensive list of all wildlife species observed on the project site can be found in the BE, located in Appendix C. Birds Numerous resident and migratory birds breed and forage on the project site. Avian species observed within the project site during the site visits include, but are not limited to: domestic chickens (Gallus spp.), American crow (Corvus brachyrhynchos), turkey vulture (Cathartes aura), red-tailed hawk (Buteo jamaicensis), wild turkey (Meleagris gallopavo), northern flicker (Colaptes auratus), Steller’s jay (Cyanocitta stelleri), black phoebe (Sayornis nigricans), barn swallow (Hirundo rustica), cliff swallow (Petrochelidon pyrrhonota), California towhee (Melozone crissalis), and others. Other species expected to occur in this habitat include Cooper’s hawk (Accipiter cooperii), red- shouldered hawk (Buteo lineatus), great horned owl (Bubo virginianus), Anna’s hummingbird (Calypte anna), downy woodpecker (Picoides pubescens), Nuttall’s woodpecker (Picoides nuttallii), and American goldfinch (Carduelis tristis). Mammals Mammals either directly observed or for which evidence of their presence was observed (scat, tracks, etc.) during site surveys were limited to Botta’s pocket gopher (Thomonys bottae), coyote
