GAP Analysis Predicted Distribution Map

Richardson's Vole (Microtus richardsoni)

Also known as a Water Vole

Species Code: MIRI

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.

Found mostly in alpine and subalpine zones, seldom more than five feet from, clear cold streams through wet meadows, in marshes and bogs, and beside small ponds bordered by wet meadows or willows. On the east slope of the Cascades rarely below 4000 feet. In the Blue Mountains, around permanent springs and small cold springs between 5000 and 6000 feet.

Core zones were Alpine/Parkland, Subalpine Fir, Mountain Hemlock, and Silver Fir zones. Water/wetlands were good habitat, and forested and non-forested zones were suitable contingent on the existence of small bogs and lakes within them.
