From the IUCN Red List Species Account:


Range Description

This species occurs on the Pacific coast of North America from southeastern Alaska to Santa Cruz County, California (Petranka 1998, Stebbins 2003). Records from the Rocky Mountains, including populations in Latah County, Idaho, and Sanders, Montana, could represent introductions, though Monello and Wright (1997) recorded three small populations in Latah County in 1997. Elevational range extends from sea level to about 2,800 m asl (Stebbins 2003).

Habitat and Ecology

Habitats include forests, woodlands, grasslands, open valleys, and ranch land. It can be found on land (in open or under rocks, logs, etc.) or in ponds, lakes, reservoirs, and slow-moving streams. It breeds in ponds, lakes, reservoirs, and slow-moving streams. Females deposit eggs singly on aquatic plants or submerged twigs (Behler and King 1979).


It is widespread and common, and its population is mostly stable. Total adult population size is unknown but surely exceeds 100,000.

Population Trend


Major Threats

No major threats are known. Road mortality is a localized threat throughout the range but does not represent a major threat.

Conservation Actions

Conservation Actions
It occurs in many protected areas.

Conservation Needed
Undeveloped buffers should be maintained around breeding sites.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of the large extent of occurrence, large number of sub-populations and localities, large population size, and use of a wide range of habitats.
