Prescribed Fire (Rx)-Planned Fires

Prescribed fire (Rx) is a planned fire; it is also sometimes called a “controlled burn” or “prescribed burn,” and is used to meet management objectives. A prescription is a set of conditions that considers the safety of the public and fire staff, weather, and probability of meeting the burn objectives. In controlled conditions, a team of fire experts use prescribed fires to help restore health to ecosystems that depend on fire. 

Fuel Treatments

Fuels treatments are mechanical, biological, or other non-fire methods of removing or altering vegetation on the landscape. Common methods include chipping, limbing, mastication, or using saws. Fuels treatments are critical to forest health, especially when the amount of vegetation in an area has built up to dangerous levels, which makes it important for crews to perform regular hazardous fuels reduction work.
