As the active wildfire season winds down across the Pacific Northwest, the Bureau of Land Management (BLM) and the U.S. Wildland Fire Service (USWFS) have launched their fall prescribed burning operations throughout Oregon and Washington. Managers say the timing is ideal: autumn moisture and cooler temperatures create conditions under which fire can be introduced into the landscape safely, reducing the fuel loads that will drive next year’s wildfire season.

Regional Burn Operations

BLM officials confirmed that prescribed burning will begin when weather, fuel moisture, and air quality conditions become favorable, with operations planned to continue through the fall and winter months. Exact ignition schedules depend on daily meteorological forecasts, atmospheric mixing conditions that determine how smoke disperses, and coordination with state air quality agencies.

The Deschutes National Forest began its own fall understory prescribed burning program in late September, with crews launching operations as early as September 25 when conditions allowed. A prescribed burn conducted approximately six miles northwest of Sunriver in mid-October prompted advisories for residents along the Deschutes River corridor — including communities in La Pine, Sunriver, and Bend — to keep doors and windows closed to minimize smoke exposure, particularly overnight and in the early morning hours when smoke tends to settle at lower elevations.

Why Prescribed Fire Matters

Prescribed fire is one of the most effective and cost-efficient tools available to land managers for reducing catastrophic wildfire risk. By intentionally burning forest understory and accumulated dead fuels under controlled conditions, managers reduce the amount of material available to fuel future wildfires. When a wildfire does occur in a treated area, it typically burns at lower intensity, moves more slowly, and is easier to contain.

The connection is direct: Oregon’s record-breaking 2026 wildfire season — which burned more than 2.1 million acres — was driven in part by decades of fire suppression that allowed fuel loads to accumulate far beyond historic levels.

Air Quality and Smoke Notifications

Residents near planned burn units can expect smoke during and after ignition operations. Smoke visibility and air quality impacts are typically greatest:

  • In the evening and overnight, when cool air settles smoke into valleys and communities
  • In the early morning hours before atmospheric mixing resumes
  • During periods of light winds with no overnight temperature inversion

Air quality agencies issue smoke advisories when prescribed burn smoke is expected to impact populated areas. Central Oregonians can monitor airnow.gov and sign up for OregonAir notifications for real-time air quality data.

Legislative Tailwind

The fall prescribed burn season comes in the wake of the U.S. Senate’s unanimous passage of the Wildfire Emissions Prevention Act of 2026 on September 29, which aims to reduce regulatory hurdles under the Clean Air Act that have historically complicated prescribed burn permitting. If enacted into law, the legislation could significantly expand the scale and frequency of prescribed burning operations in Oregon, Washington, and across the West.

Residents who observe prescribed burn smoke or have concerns about air quality can contact their local National Forest or BLM district office for information on planned operations.
