From the IUCN Red List Species Account:

 

Range Description

This species can be found from the Coast from Honeydew, Humboldt County, south to the Russian River area, Sonoma County, California, United States (Stebbins 1985).

Habitat and Ecology

It can be found in mountain streams and rivers in coastal woodlands and redwood forest. When inactive, occurs under rocks, logs, other forest debris, and in rodent burrows and subterranean crevices. Usually breeds in flowing water. Lays eggs on undersides or rocks in foothill/mountain streams. Amplexus between March and late April.

Population

It is common in many streams (Petranka 1998) and its population seems stable. Total adult population size is unknown but surely exceeds 100,000; Twitty (1966) marked 20,000+ in one study area.

Population Trend

stable

Major Threats

None known. Local populations might be impacted by deforestation, but it is not significantly threatened.

Conservation Actions

None needed. It occurs in a number of protected areas, but it would be beneficial to promote research on its natural history, population status, and the monitoring of its populations.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern since, although its extent of occurrence (EOO) is less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, and it has a presumed large population.
