WATERAX: Prescribed and controlled burns often kick off by drip torch use

摘要

Controlled burns, prescribed burns, and backfires are all similar terms for a wildland fire that is intentionally lit to create a natural firebreak in front of a main fire front, to reduce fuel buildup and decrease the potential for a hotter and more serious wildland fire, or to renew forest areas by stimulating germination of some trees and increasing seedling growth.
