A controlled burn or prescribed burn (Rx burn) is the practice of intentionally setting a fire to change the assemblage of vegetation and decaying material in a landscape. The purpose could be for forest management , ecological restoration , land clearing or wildfire fuel management.
A backfire is a more aggressive type of burning done to influence the behavior of the main fire. In forest and prairie management, the driptorch is the most common tool used to ignite prescribed burns, which are used to remove excess fuel buildup or to re-create natural cycles of fire in an ecosystem.
This study showed that prescribed fires maintained the richness of the area. Fire burns are particularly needed to sustain native plant species. They increased the proportion of native plants to non-native plants and the richness of native plants. Fall burning, in particular, increased overall and native richness.
Commentary: Burning operations in 2023 removed excess vegetation on 6,000 acres and thus reduced fire danger
Recently efforts have been undertaken by the Canada Parks system to incorporate prescribed burns. What they have found is a reduction in wildfire intensity in parks using prescribed burns though they did uncover some problems. In area with prescribed burns and a high herbivore population experience negative effects regarding in sapling occurrence.
Modern techniques for fighting these fires include controlled burns and the clearing of brush. The discontinuation of live firing at the Massachusetts Military Reservation has also contributed to the decrease in the intensity of the fires. The military has helped with the hazard by periodically burning portions of the land to prevent these ...
The Forest Service enacted similar measures in 1974 by changing its policy from fire control to fire management, allowing lightning fires to burn in wilderness areas. This included both naturally caused fire and intentional prescribed fire. [12]
Broadcast burning is commonly used to prepare clearcut sites for planting, e.g., in central British Columbia, [26] and in the temperate region of North America generally. [27] Prescribed burning is carried out primarily for slash hazard reduction and to improve site conditions for regeneration; all or some of the following benefits may accrue:
