North Carolina’s share of this cold-tolerant rodent is a disjunct outlier: the main range sits well to the north, and the state’s records trace to the high, grassy balds and boggy meadows of the western Blue Ridge and the Smokies, where cooler summers let a northern species hang on at the southern edge of its range. That’s a genuinely different story from most of its eastern range, which stays at low elevation.
Wherever it lives, this lemming cuts narrow runways through thick grass and sedge, feeding mostly on green plants, roots, and bark, with a few invertebrates mixed in. It doesn’t hibernate, staying active through the mountain winter by tunneling under snow and thick cover rather than shutting down for the season.
Reports occur in every month, with clusters in May and June and again in September. Because this lemming is secretive and difficult to detect, that pattern likely reflects the timing of targeted high-country surveys more than a true seasonal swing in activity.
