GAP Analysis Predicted Distribution Map

Heather Vole (Phenacomys intermedius)

Species Code: PHIN

Legend: = Core Habitat = Marginal Habitat Breeding Range Map The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, other datasets and experts throughout the state, as part of the Washington Gap Analysis Project.

The Heather Vole is most abundant in the Hudsonian (sub-alpine) forests, krummholz, and moist alpine meadows. Occurs in smaller numbers through lower forests in wet situations or dry sites next to small streams. At all elevations it is usually associated with low scattered evergreen shrubs or herbs. The lower elevation range limit varies with location but the higher limit is the permanent snow line.

Generally speaking, core zones were Western Hemlock and above. In the Blue Mountains, Sub-alpine Fir and High Open Forest were core. In all zones, water/wetlands, non-forested, and forest were good habitats.
