The complete county distribution, spread across 35 Montana counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Montana’s occurrence databases hold 919 records of the moose, one of the most frequently logged mammals in this survey. That count reflects how often people document a moose, not how many actually roam the state.

Two mountain strongholds, one wet habitat

The moose isn’t a single-region animal in Montana. It holds on in the wet conifer forests of the northwest corner, the Yaak, the Cabinet and Purcell mountains, and the country ringing Glacier National Park, and it shows up again in the mountain valleys of the southwest, around the Big Hole, the Gravelly Range, and the Beartooths. What ties those two areas together isn’t elevation or latitude. It’s water. Moose need willow thickets, beaver-flooded bottoms, and wet meadows, and Montana’s high, boggy valleys supply exactly that whether they sit near Glacier or near Yellowstone’s northern edge.

A summer spike tied to heat, not breeding

Records climb sharply from June through September and fall off hard the rest of the year. Moose don’t hibernate or migrate far, so that swing says more about how visible they get in warm weather. A moose overheats easily under its heavy coat, and through the hottest months it wades into ponds and slow side channels to cool off and feed on submerged plants, standing in open water where a hiker or a trail camera is far more likely to catch it than during a quiet winter in dense timber.

Status in Montana

The moose is native across its Montana range, and NatureServe ranks it S4, apparently secure. Its future here still tracks the health of the wetlands and willow bottoms it depends on more than any other single factor.
