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].

PLANT COMMUNITIES :
Meadow voles are most commonly found in grasslands, preferring moister
areas, but are also found in wooded areas [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].
