ResumoLiterature and field surveys were conducted to document occurrence of Van Dyke's Salamander (Plethodon vandykez) in Washington State. A map comparing the sala- mander's distribution with climatic and geologic variables was constructed to reveal poten- tially inhabited regions. At least 80 localities for the species are presently known. These occupy regions with >150 cm average annual precipitation, and have an upper altitudinal limit coinciding with the boundary between temperate mesophytic and subalpine forests. Disjunct population centers in the Willapa Hills, on the Olympic Peninsula, and in the south- ern Cascade Ranges are separated by glacial and alluvial deposits which appear to limit the salamander's regional distribution.
