Wyoming’s occurrence databases hold 2,768 moose records, making it one of the most frequently recorded mammals tracked in the state’s mammal cell. Every one of those records comes from GBIF rather than casual iNaturalist sightings, a split that says as much about how the data was gathered as about the animal itself.

Willow flats and high mountain drainages

Records concentrate in the willow-choked river bottoms and conifer forest of Yellowstone and the Wind River and Bighorn ranges, the kind of cold, wet country a moose needs. The Snake River’s braided channels around Jackson Hole hold some of the thickest documentation in the state, since a moose spends much of its day within reach of water and the willow and aquatic plants that make up most of its diet.

A summer surge in the records

Reports climb sharply from May through September, with June and July holding the year’s heaviest counts. That doesn’t mean moose vanish in winter. It’s a resident species that stays in Wyoming’s high country through the snow, but summer is when hikers, rafters, and field crews are out in the terrain where a moose is most likely to be standing in a stream or willow thicket.

Status in Wyoming

NatureServe ranks the moose S4, Apparently Secure, and it’s native to Wyoming. It remains one of the state’s signature high-country residents, tied closely to the same willow bottoms and snowbound drainages that keep its records concentrated in the northwest.
