Conservation Status: Least Concern.

Southern Bog Lemmings are born with whiskers and a scattering of hairs on their heads and backs. They are well-furred when they are a week old, and look like miniature adults at two weeks of age. By three weeks, they are weaned and are almost full grown. They live in a wide variety of habitats, including grasslands, mixed deciduous/coniferous woodlands, spruce-fir forests, and freshwater wetlands. They eat grasses, sedges, mosses, fungi, fruit, bark, and roots. Fossils indicate that they once lived where the Northern Bog Lemming is found today, and Southern Bog Lemmings occurred as far south as Texas and Mexico.
