Distribution and Habitat Requirements
Dunn's Salamander is found west of the Cascades from Northern California through Oregon and into Washington only in the Willapa Hills. This species is associated with streams and seepages in the Willapa Hills of Washington. Hardwood riverbank tree stands large enough to show on GAP vegetation layers were not considered suitable habitat. The Cowlitz River acts as the eastern boundary to its range limits, and the Chehalis River is its northern boundary.
The outer and Inner Olympic Peninsula ecoregions were selected. The Sitka Spruce and Western Hemlock zones were core areas of habitat. Conifer lined stream and riverbank areas were good habitats. All classes of closed-canopy hardwood/conifer and conifer forests were suitable if appropriate microhabitats existed.
