Metadata (Data about data or how the map was made)

The Silver-haired Bat occurs throughout Washington, primarily in forested zones, and probably into alpine parkland. It occurs in the Columbia Basin in small numbers which are probably migrating individuals. These bats are most closely associated with forests, roosting almost entirely in trees, usually snags. Except during migration, they hunt primarily within forests, at the forest edge, in small clearings, and along ponds and rivers. Breeding females may be restricted to lower elevations than males, but the current evidence is sparse.

Steppe zones were peripheral but all others were core. Forest and water/wetlands were good habitats; low-density development was adequate.
