Total adult population size is unknown, but certainly exceeds 10,000. However, it appears to be in decline due to habitat loss. It has been eliminated from 55-58% of historic breeding sites, and reportedly about 75% of the historical vernal pool-breeding habitat has been lost (Holland 1998) (though some question the reliability of this estimate). Barry and Shaffer (1994) stated that this salamander soon would be in danger of extinction throughout its range, and they noted that it already is gravely threatened in the San Francisco Bay Area and in the San Joaquin Valley. But Trenham et al. (2000) noted that the species still occurs in most of the historical range and can be locally common. In Santa Barbara County, of 14 documented breeding sites, half have been destroyed or have suffered severe degradation since mid-1999 (USFWS 2000).
