This species inhabits along shady streams or stream seepages in wet rocky areas; in forests, talus slopes, moss-covered outcrops, often under rocks, logs, moss and leaf-litter. Animals may enter water to escape predators. Eggs are laid on land in moist crevices or cavities, where they develop directly without a larval stage. It seems able to cope with a at least some degree of habitat modification.

This species is found in extreme southwestern Washington south to extreme northwestern California in the United States of America (Petranka 1998). It occurs at elevations from sea level to about 1,000 m asl (Stebbins 1985).
