The complete county distribution, spread across 19 Minnesota counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Northern flying squirrel records in Minnesota concentrate in the Arrowhead’s boreal forest, where Lake and St. Louis counties lead and Superior National Forest is the busiest named site. As a strictly nocturnal glider, the species is almost never seen in daylight, so records come from nest-box checks and chance after-dark encounters rather than casual daytime sightings.

Reports show a modest midsummer peak in July and August and a smaller rise in May, and 53 of the 58 records are iNaturalist sightings, so most of the documentation comes from public observation rather than research trapping. NatureServe has not yet assigned the species a Minnesota rank.
