GAP Analysis Predicted Distribution Map

Columbia Torrent Salamander (Rhyacotriton kezeri)

Species Code: RHKE

Legend: = Core Habitat = Marginal Habitat Metadata (Data about data or how the map was made) Predicted Distribution Amphibians do not migrate as some birds and mammals, so the colored areas depict the predicted range for the Columbia Torrent Salamander year-round. The habitats were identified using 1991 satellite imagery, other datasets and experts throughout the state, as part of the Washington Gap Analysis Project.

Distribution and Habitat Requirements
Torrent salamanders are specialized to a life in cold water splash zones around streams, seepages or waterfalls. This species is found south of the Chehalis River in the southwest portion of Washington. The Columbia Torrent Salamander s is thought to be associated mostly with older conifer forests but some recent studies indicate it might also be common in younger forests. This species is associated with small streams.

Models
The Outer and Inner Olympic Peninsula ecoregions were selected. the Sitka Spruce and Western Hemlock zones were core areas. Riparian area (areas along rivers and streams) were good habitats. Middle to late growth hardwood/conifer and conifer forests were suitable if appropriate microhabitats existed.
