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

Requires deep soil for burrowing, dense thickets of vegetation, and very moist situations, often near streams or springs. Occurs in forest and brush and more abundant in hardwood forest than coniferous. Does well in cut-over and second growth forest and is a significant pest in gardens and forest plantations where it eats conifer seedlings. Found from sea-level to treeline, but not above. More abundant at lower elevations and far more common west of the Cascade crest than east.

Core zones were all zones west of the Cascades below Mountain Hemlock. In all zones, low density development, fresh water/wetlands, hardwood forest, and mixed forest were good habitats. It prefers habitats with lush vegetation.
