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.

Banks Featuring this Species

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.

Ohlone West Conservation Bank (OWCB) occurs within Southern Alameda County and is immediately adjacent to the existing Ohlone Preserve Conservation Bank, owned and managed by Fletcher Conservation Lands. It is contiguous with watershed lands owned by the San Francisco PUC and wilderness preserves of the East Bay Regional Park District. OWCB has been agency-approved and is now open for mitigation needs.
