The montane vole is a small rodent that lives in mountain meadows and forests of the western part of North America. It digs long burrows and feeds on plants.
The montane vole differs from related species by living at high altitudes and in drier mountain meadows. It is important for nature as prey for predators and as an animal that churns the soil.
