The complete county distribution, spread across 7 Montana counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Wolverine records in Montana concentrate in the state’s highest, most remote mountain country, Glacier National Park, the Absaroka-Beartooth Wilderness, and Custer-Gallatin National Forest, terrain that stays snow-covered late into the year and gives this wide-ranging carnivore the cold, low-disturbance habitat it needs to den and travel.

Reports spike in February and March and again in July and August, likely tracking winter tracking surveys and summer backcountry travel rather than a true two-season activity pattern for an animal that roams huge territories year-round. NatureServe ranks the species S3, Vulnerable, in Montana, one of the last strongholds for wolverines in the contiguous United States.
