City of Pleasanton—Hidden Canyon Residences and Preserve <br />Biological Resources Draft EIR <br /> <br /> <br />3.3-8 FirstCarbon Solutions <br />https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-03 Bio Resources.docx <br />(Canis latrans), black-tailed deer (Odocoileus hemionus columbianus), brush rabbit (Sylvilagus <br />bachmani), eastern fox squirrel (Sciurus niger), and domestic cattle (Bos taurus). <br />Neither California ground squirrels (Otospermophilus beecheyi) nor their burrows were observed <br />during site visits, likely due to an ongoing ground squirrel eradication effort on the ranch for several <br />years by the landowner. Although not observed, other small mammals that may occur in this habitat <br />include western harvest mouse (Reithrodontomys megalotis), California meadow vole (Microtus <br />californicus), deer mouse (Peromyscus maniculatus), western gray squirrel (Sciurus griseus), striped <br />skunk (Mephitis mephitis), and raccoon (Procyon lotor). <br />Reptiles <br />Several reptile species were observed during site visits. These included western fence lizard <br />(Sceloporus occidentalis), Skilton skink (Eumeces skiltonianus skiltonianus), California alligator lizard <br />(Elgaria multicarinata), gopher snake (Pituophis catenifer), California kingsnake (Lampropeltis <br />californiae), and northern Pacific rattlesnake (Crotalus oreganus oreganus). <br />It is possible that Alameda whipsnakes (Masticophis lateralis euryxanthus) may use different habitats <br />within the project site for hibernation, food sources, and foraging opportunities. <br />3.3.4 - Special-status Species <br />Special-status species are plant and animal species that have been afforded special recognition by <br />federal, State, or local resource agencies or organizations. Listed and special-status species are of <br />relatively limited distribution and may require specialized habitat conditions. Special-status species <br />are defined as meeting one or more of the following criteria: <br />• Listed or proposed for listing under the California Environmental Species Act (CESA) or the <br />federal Environmental Species Act; <br />• Protected under other regulations (e.g., the Migratory Bird Treaty Act [MBTA ]; <br />• Designated as a California Department of Fish and Wildlife (CDFW) Species of Special Concern; <br />• Ranked by the California Native Plant Society (CNPS); or <br />• Receive consideration during environmental review under the California Environmental <br />Quality Act (CEQA). <br /> <br />Special-status Plants <br />The California Natural Diversity Database (CNDDB) and CNPS identified 23 special-status or sensitive <br />plant species that have been recorded within the Dublin, California quadrangle and the eight <br />surrounding quadrangles (Appendix C). However, only Congdon’s tarplant (Centromadia parryi ssp. <br />Congdonii) was found on the project site. All remaining special-status plant species have been <br />determined unlikely to occur on-site based upon the results of the species review, habitat present, <br />and the nine focused botanical surveys conducted in 2014, 2016, 2017, 2019, and 2023.
