Conservation Status: Least Concern.

Southern Red-backed Voles, like other voles, are active year-round. They do not hibernate or reduce their metabolism and enter a state of torpor to conserve energy against the cold. They breed from March through November, producing two or three litters of 4-5 young each year. By three months of age, the young voles are sexually mature and ready to reproduce. This species is semi-fossorial, using burrow systems built by other rodents and natural aboveground runways through logs, rocks, and roots of trees.

Also known as:
Red-backed Vole, Gapper's Red-backed Mouse, Boreal Red-backed Vole, Red-backed Mouse

Sexual Dimorphism:
