Arkansas’s Interior Highlands carry the bulk of the state’s groundhog records, 485 of them, clustered around Devil’s Den State Park and Ozark National Forest in the Boston Mountains and around Hot Springs National Park in the Ouachitas.
A digger that needs an opening in the trees
Groundhogs are burrowers first and foremost, and their burrow systems, multiple entrances, separate nesting and waste chambers, a hibernation chamber dug below the frost line, need open, well-drained ground to build in. That means they concentrate at the forest edges, clearings, roadside cuts, and valley-bottom pastures scattered through the Ozark and Ouachita highlands rather than the deep unbroken timber that covers most of both ranges. A grazer on grasses, clover, and other low forbs, a groundhog rarely wanders far from the burrow it’s digging into that open ground.
True hibernators on a spring-heavy calendar
Unlike Arkansas’s chipmunks, which wake every few days through winter to raid a food cache, groundhogs are true hibernators, dropping their body temperature and heart rate for months at a stretch and living entirely off stored fat. Records here are almost silent from December through February, then climb sharply once animals emerge in spring, peaking in May as groundhogs are most active above ground feeding and, for females, raising young.
Status in Arkansas
NatureServe ranks the groundhog S4, apparently secure, in Arkansas, and it’s native across its range in the state. The forest-edge habitat it needs is common wherever the Ozark and Ouachita highlands meet cleared ground, which helps explain why it’s one of the more frequently reported mammals in this data.
