Voles
HEATHER VOLES (Phenacomys intermedius)
These voles are found from 7,000 to 12,000 feet in the forested mountains of central Colorado. They occupy a variety of habitats but are most abundant along streams
DAMAGE
Voles can cause extensive damage to forest, orchards and ornamental plants by girdling trees and shrubs. They prefer the bark of young trees but will attack any tree, regardless of age, when food is scarce. Most damage occurs in the winter when voles move through their grass runways under the protection of snow. The greatest damage seems to coincide with years of heavy snowfall
