Arkansas’s occurrence databases hold 494 eastern chipmunk records, concentrated in two very different mountain ranges: the Ouachitas around Hot Springs National Park and Ouachita National Forest, and the Ozark Plateau along Buffalo National River.
A hoarder built for oak-hickory country
The chipmunk’s expandable cheek pouches exist for exactly the forest it lives in here. Acorns and hickory nuts from the oak-hickory stands that cover both the Ouachita and Ozark highlands get carried back, pouch-full at a time, to an underground burrow system with separate chambers for nesting, food storage, and waste. Those burrows, often started under a rock, stump, or log with a well-hidden entrance, let a chipmunk sit out the coldest stretches of an Arkansas winter in a state closer to deep torpor than true hibernation, waking every few days to feed from its cached stores rather than sleeping straight through.
Two mountain ranges, one active season
Records climb sharply in spring, peak in May, and stay elevated into early summer, tracking the months when chipmunks are most active above ground gathering food and raising young. The Ouachitas and the Ozarks are geologically distinct, the Ouachitas run in folded east-west ridges while the Ozarks are a dissected plateau, but the oak-hickory forest both ranges share gives the chipmunk the same food supply and burrow-friendly ground in either place.
Status in Arkansas
NatureServe ranks the eastern chipmunk S4, apparently secure, in Arkansas, and it’s native across its range in the state. Between the two highland regions and the hardwood cover they carry, it’s one of the state’s most frequently recorded woodland mammals.
