The Boise National Forest wrapped up a successful spring prescribed fire season, completing seven planned burns across the forest — with the Poorman Prescribed Fire on the Emmett District remaining active on InciWeb at approximately 2,692 acres as crews finalize mop-up and monitoring.

The spring program represents a significant investment in reducing hazardous fuel loads across Idaho's Treasure Valley foothills and adjacent forested landscapes, which face above-normal wildfire potential this summer.

Poorman Prescribed Fire

The Poorman unit, located approximately two miles east of Garden Valley off Banks-Lowman Road near the Forest Service Garden Valley Work Center, is among the largest individual units completed this season. The burn is part of a long-term effort on the Emmett District to treat ladder fuels that could carry a wildfire from the forest floor into the tree canopy and toward nearby communities.

Other completed burns on the Boise National Forest this spring included the Pinney Slope unit (1,019 acres, six miles north of Crouch off Scriver Creek Road 693) and the High Fork unit (419 acres). In total, seven prescribed burns were successfully implemented across the forest before the prescribed fire season closes ahead of the peak fire weather period.

Why Prescribed Fire Matters

Land managers use prescribed fire as a proven tool to reduce the amount of fuel — dead wood, brush, and dense understory vegetation — available to feed a wildfire. When a wildfire does ignite in a treated area, it tends to burn with lower intensity, is easier for crews to suppress, and causes less damage to both the ecosystem and nearby structures.

The alternative — allowing fuels to accumulate unmanaged for decades — increases the likelihood of catastrophic wildfire that is far more difficult to control and far more damaging to communities, watersheds, and wildlife habitat.

Other Regional Prescribed Fire Activity

Beyond Idaho, prescribed fire programs are active across the Northwest this spring and early summer:

  • The Rogue River-Siskiyou National Forest in Oregon has an active prescribed fire operations program listed on InciWeb, with units planned in the Medford and Ashland ranger districts.
  • The Bureau of Land Management has planned spring burns in northern Idaho, including the Lynch Gulch understory burn near Pinehurst, where smoke will be visible from Interstate 90.
  • The San Juan National Forest in Colorado's 2026 prescribed fire program is ongoing, as are projects on multiple forests in the Great Lakes region.

Smoke and Public Notice

Prescribed burns produce smoke, and land managers are required to coordinate with state air quality agencies before igniting units. Oregon DEQ and the Idaho Department of Environmental Quality both operate smoke management programs that agencies must comply with. Residents near active burn units may experience reduced visibility and air quality impacts during and shortly after ignitions.
