The Umatilla National Forest is ready to start burning 2,000 acres to 10,000 acres this spring to reduce wildfire risk, help with planting and improve wildlife habitat.
Federal, state and local government employees, as well as contractors, will do the burning, sometimes using bulldozers and helicopters.
A fire line is often built around areas to be burned, using roads and trails as fire breaks. Fires might be ignited by workers with drip torches or helicopter-mounted firing devices.
Burning often follows harvest or other thinning activities that remove some trees while retaining the largest, healthiest trees of the most fire-resistant species, such as ponderosa pine and western larch.
