Range DescriptionThis species can be found in Willapa Hills, and Olympic and Cascade mountains, Washington, USA; disjunctive centres in the Willapa Hills, on the Olympic Peninsula, and in the southern Cascade ranges are separated by glacial and alluvial deposits that might limit the regional distribution (Wilson et al. 1995). It coexists with Dunn salamander southeast of South Bend, Pacific County, Washington (Stebbins 1985). It generally occurs in small isolated subpopulations, up to 1,550 m asl. Its range, taken here as a proxy for extent of occurrence (EOO), is estimated at 18,924 km2 (Raffaëlli 2007).
