|Scientific Name:||Plethodon dunni|
|Species Authority:||Bishop, 1934|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Hammerson, G.A. & Garcia Moreno, J.|
|Facilitator/Compiler(s):||Garcia Moreno, J.|
Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification and presumed large population.
|Range Description:||This species is found in extreme southwestern Washington south to extreme northwestern California, USA (Petranka 1998). It is found from sea level to about 1,000 m asl (Stebbins 1985).|

|Population:||Many unthreatened populations are known.|
|Habitat and Ecology:||It is found 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.|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||It is not strongly tied to old growth forest; it can be abundant in forests of all ages, though it is more likely to be present in logged forests when mature timber is present upstream (Corn and Bury 1991); hence, logging is not considered to be a major threat to this species.|
|Conservation Actions:||No conservation measures are needed for this species. It occurs in many protected areas.|
