Least weasels are North America’s smallest carnivore, and South Dakota’s record for the species is thin: 8 records since 2000, every one an iNaturalist observation, 3 of them also carried in GBIF. That’s a twist for an animal this small and fast, which usually turns up in a trap before it turns up in a photograph. NatureServe rates the state population S5, secure, despite the genuinely thin record.
Records scatter across six months, two in February and one each in April, May, June, August, and September, too sparse a pattern to describe any real seasonal trend beyond confirming occasional detection through the year.
