And after a fire, the additional sunlight and open space in a forest can help young trees and other plants start to grow. It returns nutrients to the soil in the ashes of vegetation that could otherwise take years to decompose. Controlled burns can also reduce insect populations and destroy invasive plants. By ridding a forest of dead leaves, tree limbs, and other debris, a prescribed burn can help prevent a destructive wildfire. Pile burning is sometimes used to burn slash, the remnants of forest thinning or logging operations.Ĭontrolled burns are lit for a number of reasons. ![]() In this case, leaves, limbs, and other debris are cut, collected, and stacked up to be burned, often at a later time when weather conditions permit. Pile burning can be used when conditions are not safe to set a larger fire. The second, pile burning, involves stacks of vegetation that are burned individually. The first, broadcast burning, involves lighting fires across a tract of land, from a few hectares to thousands of hectares in size. Two types of controlled burning are most commonly used. Controlled-burn managers also map out how the fire will be set, how the smoke will be managed, how to inform the public, what protective equipment might be needed, and what firefighting resources should be standing by. It also includes the weather and environmental conditions under which the fire will burn and any situations that might require the fire to be extinguished. This plan includes details on how big the fire will be, what it will burn, and what managers hope to accomplish with the fire. Materials burned in a planned fire include dead grass, fallen tree branches, dead trees, and thick undergrowth.īefore a controlled burn is lit, a plan-or prescription-is drawn up. In addition, forest conditions should call for a controlled burn and weather conditions should be right to allow burning but not enable a fire to spread out of control. These burns are scheduled for a time when the fire will not pose a threat to the public or to fire managers. Controlled burning, also known as prescribed burning, involves setting planned fires to maintain the health of a forest. ![]()
