With the peak of wildfire season giving way to cooler temperatures and the first significant autumn rains, land managers in the Bitterroot Valley are moving quickly to take advantage of narrow windows of safe burning weather to conduct prescribed fire operations that were impossible during the height of summer. The Bitterroot National Forest has announced plans for fall prescribed burns covering thousands of acres across multiple ranger districts in southwest Montana.

The Stevensville Ranger District, working in partnership with Montana Fish, Wildlife and Parks, conducted up to 500 acres of prescribed burning on September 23 and 24 in the 3-Mile Wildlife Management area near Stevensville. Additional planned projects include approximately 3,000 acres near Cameron Gap east of Conner, 1,800 acres southeast of Hamilton near Skalkaho Highway, and 1,800 acres southwest of Conner in the Piquett Creek area.

Why Fall Prescribed Fire Matters

Prescribed burning in the fall serves multiple objectives. It reduces accumulated surface fuels — grasses, brush, and dead woody debris — that would otherwise become hazardous fuel loads fueling next year's wildfire season. It also promotes forest health, improves wildlife habitat, and in some areas helps regenerate native vegetation communities that depend on periodic low-intensity fire.

The 2026 fire season made painfully clear the consequences of decades of fire exclusion across western landscapes. Forests with dense, continuous fuel beds burned with extreme intensity this summer, creating conditions that were nearly impossible to suppress. Prescribed fire is one of the most effective tools land managers have to reduce that risk before the next fire season arrives.

Nature Grove Fire Update

The Nature Grove Fire continues to burn on the Bitterroot National Forest, located 13 miles east of Hamilton south of Highway 38. As of September 25, the fire stands at 1,422 acres with 0% perimeter containment. However, fire behavior has become minimal — showing only creeping behavior following recent precipitation and cooler autumn weather — and the fire is not considered an active threat to communities at this time.

Fire managers are monitoring the Nature Grove Fire closely and will adjust tactics as conditions allow. No evacuation orders or warnings are currently in effect for areas near the fire. The Bitterroot National Forest fire information line can be reached at 406-420-3096.

The Prescribed Fire Challenge

The 2026 season highlighted both the urgency of prescribed burning and the difficulty of accomplishing it. According to NIFC, prescribed burning and mechanical fuel reduction strategies faced significant limitations throughout 2026 due to narrow windows of safe weather conditions and ongoing drought, constraining mitigation efforts during the critical peak season.

Land managers, conservation groups, and legislators across the West have called for more resources and more flexible regulatory frameworks to allow agencies to conduct more prescribed burns in the fall and winter months — the windows when fire can be used as a tool rather than fought as a threat. Several states are actively reviewing their prescribed burn liability laws to encourage more private landowner participation in fuel reduction programs.

Smoke Awareness

Residents in the Bitterroot Valley and surrounding communities should be aware that fall prescribed burns may produce visible smoke, particularly in the early morning and evening hours when smoke tends to settle into valleys. The burns are carefully planned to minimize smoke impacts, but air quality may be temporarily affected on burn days. Residents with respiratory conditions should monitor air quality at AirNow.gov on days when burns are active.
