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

The Montane Shrew occurs in all coniferous forest zones in Washington, but is most abundant in mesic to moist zones. Also common in the Humid Transition zone of western Washington. Much less common in the Arid Transition zone (Ponderosa Pine) on the east slope of the Cascades. Common in the Douglas-fir zone and upward in the northeast part of the state. Found in a variety of habitats including streams, dry forests, talus slopes, dense rain forests, cuts in wet forest, heather, bogs and muskegs.

Found in all regions but only at the margins of the Columbia Basin. All forested zones were core except for the Ponderosa Pine, Oak, and Lava Flows, which were peripheral. Forests and water/wetlands were good habitats in all zones. Excluded from bare ground, developed, and agriculture in all zones.
