Habitat and Ecology [top]

Habitat and Ecology:Taiga voles prefer early successional stage forests, especially black spruce in riparian habitats. They require rhizomes for winter food and good burrowing conditions such as occur where there is heavy moss cover. Because the preferred habitat may be limited in duration, populations are ephemeral and patchy in distribution. They make burrows with large dirt piles at the entrances. They also make runways through sphagnum.

Young are born in underground burrows. In Alaska, litter size averages 8.8 (range 6-13). Females will produce one or two litters per year. The young of year do not breed (Wolff and Lidicker 1980). Grasses, horsetails, and lichens are important in the diet of these voles, they also eats blueberries (Whitaker 1980).
