Least weasel sits at the very bottom of Minnesota’s mammal record count, just 4 iNaturalist sightings against 33 from GBIF, in a state where records already run through Superior National Forest, the Boundary Waters Canoe Area Wilderness, and Voyageurs National Park. As the smallest carnivore in North America, small enough to follow rodents into their own burrows, it’s rarely seen even where it’s genuinely present.
With records this sparse, the state’s seasonality is flagged as poorly documented rather than described with a confident peak. NatureServe ranks the species S3, Vulnerable, in Minnesota, a real conservation concern layered on top of a predator that was always going to be hard to count.
