Vole

Voles can cause serious damage and even death of woody plants. Voles have short tails while house mice and other mice have a relatively long tail. The coloring is similar, although a vole is about half again bigger than house mouse. Vole damage usually occurs during the winter. It often occurs in landscapes where there is a "natural or wild" area that touches the property line. Vole damage also occurs in landscapes that have naturalized areas, deep mulches,or large groupings of ornamental grasses or groundcovers. These give the voles a suitable habitat that allows them to breed and reduces predation on the voles. Voles eat the bark and cambium off of many plants during the winter when more suitable food supplies are limited. If the vole girdles the branch or trunk the plant above that location dies. Snow of three or more inches on the ground allows the vole to tunnel under the snow from the normal habitat to the junipers, arborvitae, fruit trees or other plants to feed on the bark and cambium.

Voles will also feed on turf, particularly near protected areas as listed above. They feed on the roots, stems, and shoots of the grass, leaving meandering trails and runways about two inches wide. Occasionally, burrows 2-3 inches in diameter will be dug deeper into the soil.
