Least chipmunk records in Minnesota cluster at Agassiz, Tamarac, and Rice Lake national wildlife refuges, all in the state’s northwestern prairie-and-wetland country near the edge of a range that otherwise spans boreal Canada and the northern Rockies. All 149 records come from iNaturalist, with no GBIF specimen data behind them.
Reports run from June through September and peak in August, tracking the warm months when this small, ground-dwelling chipmunk is most active foraging before winter hibernation. NatureServe has not yet assigned the species a Minnesota rank, though its edge-of-range position here makes it notably less common than in the boreal forests farther north and west.
