Least weasel sits near the very bottom of Minnesota’s mammal record count, with just 4 records since 2000, all of them iNaturalist sightings and three of them single reports from Pine, Dakota, and Cook counties. 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.
