|Scientific Name:||Dicamptodon copei|
|Species Authority:||Nussbaum, 1970|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species can be found in the Olympic Peninsula, Washington, south through the southern Cascades and Willapa Hills to streams that drain into the Columbia River Gorge in northwestern Oregon, USA (Stebbins 1985). It can be found from near sea level to about 975m asl (Leonard et al. 1993).|

|Population:||The total adult population size is unknown but it probably exceeds a few thousand. Trend is poorly known. Declining to stable in Oregon (M. Stern pers. comm., 1997). Probably stable for the past 20 years in Washington where at least 100 localities are known (J. Fleckenstein pers. comm., 1997).|
|Habitat and Ecology:||It can be found in streams and rivers in moist coniferous forests (water temperatures usually range from 8-14 C) (Nussbaum et al. 1983). It is sometimes found in clear, cold mountain lakes and ponds, and sometimes occurs on land along water courses (Jones and Corn 1989). It lays eggs in nest chambers under stones, cutbanks, or logs (Nussbaum et al. 1983).|
|Major Threat(s):||Logging is the biggest threat to this species; logging could increase water temperatures to unsuitably high levels and result in siltation, which might detrimentally affect food resources. Overall, it is considered to be only locally threatened.|
|Conservation Actions:||Numerous sites are protected in Washington.|
