|Scientific Name:||Batrachoseps pacificus|
|Species Authority:||(Cope, 1865)|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern since, although its Extent of Occurrence is much less than 5,000 km2, it is common and occurs in an area of extensive, suitable habitat which appears not to be under threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species is restricted to Anacapa, Santa Cruz, Santa Rosa, and San Miguel islands, off the coast of Santa Barbara, California, USA (Jockusch et al. 1998, 2001; Wake and Jockusch 2000).|

|Population:||Total adult population size is unknown, but the species is extremely abundant throughout the limited range.|
|Habitat and Ecology:||It can be found in oak woodland, chaparral, and grassland, under stones and wood. It is a terrestrial breeder.|
|Major Threat(s):||Unthreatened if present land ownership is maintained.|
|Conservation Actions:||All islands are protected within either the Channel Islands National Park or by The Nature Conservancy.|
