Geographic Range Townsend's voles, Microtus townsendii , are restricted along the western coast of North America, primarily found in Washington, Oregon, and northwest California.

The ADW Team gratefully acknowledges their support. Then, farmers can consider targeted solutions after matching their symptoms. Voles can also be recognized by their travelling habits. They create holes of about five centimetres in diameter and there are no dirt piles over these holes which lead to tunnels often visible on the surface of the ground as runway depressions. Voles will stay close to their food source so they will burrow along blueberry bush rows in fall and winter.
Together with a trap from Goodnature, an innovative rodent trap company in New Zealand, the pair are working to create a lasting attractant for the trap. Therefore, one great potential way to attract voles is by tapping into their natural communication pathway, possibly by using soiled bedding that captive voles have been housed on, to use as a lure in our traps. We are also aiming to test more conventional food attractants to see if these are effective.
It must be specially formulated so that it lasts a significant period of time without turning moldy. Their fur is dark brown in colour and often tipped with black, while their bellies are dull grey, and they have medium sized ears.
Garry Oak meadows are a key habitat for these rodents. Voles feed on the roots of grasses, sedges, and other soft-stemmed plants, as well as fallen seeds and leaves. Although it prefers fields and meadows, our native vole is a strong swimmer that often lives in wetlands and can burrow into stream banks underwater.
Up to nine inches long, it is sometimes mistaken for a muskrat! We have begun collecting road-kill and cat-kill voles for genetic analysis to find out how isolated they really are from their mainland cousins. Island voles form extended families of up to several hundred individuals living in subterranean burrows connected by networks of runways on the soil surface.
Most active at night, voles feast on fresh green stems and leaves in summer, but depend on digging up and caching bulbs, corms and tubers the rest of the year. Digging is particularly obvious in January to April, as voles clean out their burrows and search frantically for fresh bulbs and tubers to replenish their winter stores and feed their first litter of the year.
