What is considered aerial fuel?

Aerial fuel refers to combustible material that is elevated above the ground, which makes it accessible for fire spread and significantly impacts fire behavior. In this context, foliage that is at least 6 feet above the ground qualifies as aerial fuel because it can contribute to the spread of flames through the tree canopy or along elevated vegetation.

Elevated fuels are particularly important in understanding fire dynamics, as they can facilitate the movement of fire in a more rapid and unpredictable manner compared to fuels that are on the ground. The arrangement and condition of this aerial fuel can affect how heat, flames, and smoke travel, thus playing a crucial role in fire suppression strategies and safety measures.

In contrast, leaves on the ground or bushes near the ground primarily represent surface or ground fuels, while pine cones on trees may be considered part of the tree structure but do not primarily contribute to the aerial fuel component unless they are in sufficient quantity and positioned in the upper canopy.
