Usually associated with streams, seepages, and rock outcrops, it is endemic to Washington where it is found in a limited number of small, isolated populations.

They avoid the summer heat and the freezing temperatures of winter, seeking shelter beneath stones or within rotting logs.

They generally occur in small isolated populations that are usually associated with streams, seepages, and rock outcrops.

In coastal areas, it is mostly found in old forest stands that have moderate to high levels of woody debris and fractured rock present.

[4] Threats to the Van Dyke's salamander are not well studied, but patchy distribution and low population densities would indicate that this species should receive conservation attention.

Populations are at risk from logging, road construction, and other activities that could impact or degrade their specific habitat requirements.
