WILDLIFE DISTRIBUTION AND OCCURRENCE

WILDLIFE SPECIES: Microtus pennsylvanicus | Meadow Vole
GENERAL DISTRIBUTION : The meadow vole has the widest distribution of any North American species of Microtus. It ranges from Labrador west to Alaska and south from Labrador and New Brunswick to South Carolina and extreme northeastern Georgia; east through Tennessee, Missouri, north-central Nebraska, the northern half of Wyoming, and central Washington to Alaska; south through Idaho into north-central Utah. It is excluded only from the extreme polar regions. A disjunct subset of its range occurs from central Colorado to northwestern New Mexico [2,48].

In eastern Washington and northern Idaho meadow voles are found in relative abundance in sedge (Carex spp.) fens but not in adjacent cedar (Thuja spp.)-hemlock (Tsuga spp.), Douglas-fir (Pseudotsuga menziesii), or ponderosa pine (Pinus ponderosa) forests. Meadow voles are also absent from fescue (Festuca spp.)-snowberry (Symphoricarpos spp.) associations. It was speculated that moisture is a major factor in habitat use; possibly the presence of free water is a deciding factor. In southeastern Montana meadow voles were the second most abundant small mammal (after deer mice [Peromyscus maniculatus]) in riparian areas within big sagebrush (Artemisia tridentata)-buffalo grass (Buchloe dactyloides) habitats [40]. Meadow voles are listed as riparian-dependent vertebrates in the Snake River drainage of Wyoming [52]. Raphael [47] compiled 11 studies on small mammals; meadow voles were reported in only 3 of 29 sites in subalpine forests of the central Rocky Mountains. Davis [12] suggested in 1939 that meadow vole range extensions were likely to be related to irrigation practices. Meadow voles are now common in hayfields, pastures, and along ditches in the Rocky Mountain states [30]. In Pipestone National Monument, Minnesota, meadow voles were present in riparian shrublands, tallgrass prairie, and other habitats [57]. In east-central Ohio meadow voles were captured in reconstructed common cattail (Typha latifolia) wetlands [37]. In Virginia meadow voles were least abundant in eastern redcedar (Juniperus virginiana) glades and most abundant in fields with dense grass cover [38]. REFERENCES : NO-ENTRY
