Distribution of Van Dyke’s salamander (Plethodon vandykei).

A survey is being conducted to document the distribution of Plethodon vandykei and factors correlated with its occurrence. This will entail visiting all known populations in Mount St. Helens National Volcanic Monument, searching for additional populations in the Monument, and recording aspects of the habitat associated with each population visited. By providing a more complete picture of the distribution of the salamander than is presently available, the proposed study will permit monitoring and further study of this species’ populations and also enhance understanding of its habitat associations.
