The Ohlone Preserve Conservation Bank(OPCB) is located in Southern Alameda County and has been open since 2005. The bank contains 640 acres of oak woodland, chaparral, and grassland habitat. It is bisected by San Antonio Creek and has four perennial ponds on the site that support breeding CA tiger salamanders and CA red-legged frogs. The extensive chamise chaparral provides excellent habitat for the Alameda whipsnake which exists on site. The OPCB contains habitat that supports numerous native species of plants and wildlife. The OPCB, along with 1280 additional contiguous acres, is owned and managed by Fletcher Conservation Lands. The preserve forms an extensive contiguous land mass with watershed lands of the San Francisco PUC and openspace preserves of the East Bay Regional Park District.
The Alameda whipsnake is a long, slender snake with a dark dorsal color, usually black, dark brown or charcoal, and a ventral color of yellow or orange, often including a salmon color along the last portion of the snake's underside. It has yellow stripes along both sides of its body but not on top. It has relatively large eyes and hunts visually, seeking out and capturing lizards by rapid bursts of speed. A member of the racer family, this subspecies of the California racer occurs in Alameda, Contra Costa and parts of Santa Clara counties.
The California red-legged frog (CRF) is the largest native ranid frog in California. It breeds in ponds, wetlands and slow-moving streams. It is listed as a federally threatened species by the USFWS. The CRF occurs within numerous habitat types including oak woodland, annual grassland, and riparian and wetland habitat.
