Transitions: Summer to Fall, Wildfires to Prescribed Burns, Oct. 15

As fall weather finally begins to take hold after the long wildfire season, many forest landowners are shifting to another form of fire. Prescribed burning removes downed woody material from the forest, reducing wildfire risk when next summer rolls around. And when conducted following timber harvest, these controlled fires help prepare the soil for replanting of young trees. In addition to clearing excess vegetation that would otherwise compete with young trees soon to be planted, prescribed burning releases nutrients into the soil to jumpstart their growth. Oregon’s Forest Practices Act, the first in the nation, requires replanting after logging. To minimize smoke intrusions into populated areas, Oregon Department of Forestry meteorologists daily monitor weather conditions, and issue forecasts and burning instructions throughout the fall prescribed burning season. To prevent excessive smoke caused by too many burns at one time, the weather forecasters coordinate hundreds of burning requests from private and public forest landowners. In contrast to prescribed burns, which take place in fall and also spring, large wildfires typically occur in summer when weather conditions often trap smoke in populated valleys for an extended period. Since 1972, the Oregon Department of Forestry (ODF) has regulated forestland burning in the state under the Oregon Smoke Management Plan. Though smoke intrusions into populated areas occasionally occur due to unexpected changes in weather and wind conditions, ODF’s oversight of prescribed burning minimizes such occurrences.
