Across its broad northern range it favours damp tundra and moist meadows near water. It remains active all year, making surface runways in summer and snow tunnels in winter, and stores seeds and roots in burrows. Food includes grasses, sedges and seeds. Females produce three to six litters, each containing three to nine young. (Wikipedia, general species account)
