<br /> 33 <br />TABLE 2B: SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY. <br />ANIMALS (adapted from CDFW 2023) <br />Species Listed as Threatened or Endangered under the State and/or Federal Endangered Species Acts <br />Common and scientific names Status <br />General habitat <br />description *Occurrence in the study area <br />California red-legged frog <br />Rana draytonii <br />FT, CSC Rivers, creeks and stock <br />ponds of the Sierra <br />foothills and coast <br />range, preferring pools <br />with overhanging <br />vegetation. <br />Possible. LOA Senior Associate <br />Herpetologist Dr. Mark Jennings <br />visited the site on March 28, 2014, <br />to assess the site for suitability to <br />support special status amphibians <br />and reptiles. Dr. Jennings found <br />that breeding habitat for the CRLF <br />is absent from the site, as the creek <br />and other drainages lack deep <br />pools of water required for <br />breeding. Devaney Canyon may act <br />as a dispersal corridor for CRLF <br />should CRLF occur in nearby stock <br />ponds or pools. Much of this <br />canyon and the eastern section of <br />the project site is within Critical <br />Habitat designated by the USFWS <br />for the CRLF. The site is within <br />modeled potential upland habitat <br />for CRLF and the West mitigation <br />area of the EACCS. <br />Alameda whipsnake <br />Masticophis lateralis <br />euryxanthus <br />FT, CT Ranges from the inner <br />coast range in western <br />and central Contra <br />Costa and Alameda <br />counties. Typically <br />occurs in chaparral and <br />scrub habitats with rock <br />outcrops and talus <br />pilings. Also occurs in <br />scrub communities, <br />grasslands, oak, and <br />oak/bay woodlands. <br />Possible. LOA Senior Associate <br />Herpetologist Dr. Mark Jennings <br />visited the site on March 28, 2014, <br />to assess the site for suitability to <br />support special status amphibians <br />and reptiles. Dr. Jennings found <br />that suitable habitat exists onsite <br />for all life stages of the whipsnake. <br />The rock piles provide hibernacula <br />and food sources, riparian and <br />mixed woodlands and occurring <br />onsite provide suitable habitat, and <br />the grasslands are adjacent to <br />these woodlands, which may be <br />used for feeding and dispersal <br />habitat. The site is located almost <br />entirely within Critical Habitat <br />designated by the USFWS for the <br />Alameda whipsnake. The site is <br />within Alameda whipsnake <br />Recovery Unit 3 mitigation area of <br />the EACCS.
