Controlled burning, or prescribed fire, is a vital tool in wildland firefighting and land management. When done under the right conditions, it reduces fuels, supports healthier landscapes, and lowers the risk of large, destructive wildfires. These burns are typically carried out using three different burn techniques: backing fires, flanking fires, and head fires. Each serves a specific purpose in how crews guide and control fire.
WHAT IS CONTROLLED BURNING
Controlled burning is the intentional use of fire under carefully planned conditions to manage vegetation, lower wildfire risk, and maintain healthy ecosystems. While there are several types of controlled burns, backing, flanking, and head fires are the most common techniques used in prescribed fire assignments. Each technique results in different fire intensities and outcomes, allowing crews to plan their approach according to the landscape and environmental factors.
THE IMPORTANCE OF CONTROLLED BURNING
Using fire to prevent fire has a long history in wildland management and remains a crucial tool today. As a natural part of many ecosystems, controlled fire helps maintain healthy forests by reducing tree density, improving wildlife habitat, encouraging new vegetation growth, and lowering the risk of severe wildfires.
TYPES OF CONTROLLED BURNING
BACKING FIRES
Burning into the wind, backing fires are low-intensity with shorter flames and a longer residence time. They are ideal for consuming twigs, brush, and other smaller fuels safely.
FLANKING FIRES
Flanking fires burn parallel to the wind, producing medium-intensity flames with moderate height and residence time. With less wind influence, these fires allow crews to safely burn taller vegetation.
HEAD FIRES
Burning with the wind, head fires are high-intensity, fast-moving flames with shorter residence time. These are only ignited after backing and flanking fires have been established to ensure safety and control.
THE GEAR YOU NEED
Carrying out prescribed burns safely requires the right gear. From protective clothing to drip torches and hand tools, crews rely on high-quality equipment to stay safe, efficient, and in control on the fireline.
