Habitats of Three Oregon Voles
1964
Goertz, John W.
Voles of the species Microtus oregoni oregoni, M. townsendii townsendii, and M. montanus canicaudus were collected from Coast Range and Williamette Valley habitats in webstern Benton County, Oregon, from June 1957 to January 1959, in an effort to determine habitat preferences. Collecting results indicate that the Oregon vole is a species of the Coast Range mountains. It is found in all Coast Range (Douglas fir) habitats, but prefers grassy cutover areas. Townsend voles are most closely associated with both Coast Range and Valley riparian situations especially where dense stands of sedge and grass occur. The gray—tailed vole is found on all agricultural lands, especially in fields and pastures of grass and legumes and along fence rows. This species is not associated with Coast Range habitats. The gray—tailed vole is at all times a potential agricultural pest.
