Minnesota’s occurrence databases hold 1,083 records for the groundhog, most frequently reported around Chippewa National Forest and the bluffland state parks of the southeast. That count reflects a habit of digging conspicuous burrows in places people notice, not a formal tally of every burrow in the state.
Bluffs, pastures, and woodland edges
A groundhog needs well-drained soil it can dig into and open forage nearby, a combination the driftless southeast supplies especially well: the steep, grassy slopes and rocky outcrops around Whitewater State Park and the neighboring bluffland parks give it both the burrowing ground and the pasture edge it favors. The same pairing of woodland edge and open field shows up statewide, from farmstead fence lines to the mixed forest and clearings around Chippewa National Forest in the north-central lakes region.
A true hibernator, unlike its rodent neighbors
Where an eastern chipmunk wakes every few days through winter to raid its cache, a groundhog drops its body temperature and heart rate to near-dormant levels and stays there for months without waking to feed. That difference shows clearly in the records: sightings are close to zero from November through February, then climb fast in March as animals emerge, and peak in May once they’re fully active and feeding on the season’s new grass and clover.
Status in Minnesota
NatureServe hasn’t assigned Minnesota’s groundhog a numeric rank, but it’s native to the state. Its statewide mix of diggable soil and open forage, from bluff country pastures to north-woods clearings, keeps it a familiar and frequently recorded animal wherever those two habitats meet.
