What kind of fire does a "crown fire" refer to?

A crown fire refers to a specific type of wildland fire that spreads through the canopy or tops of trees. This type of fire is characterized by its ability to move rapidly through the upper foliage, often fueled by dry conditions and strong winds. Crown fires are particularly dangerous due to their intensity, speed, and the height at which they spread, making them difficult to control and posing significant threats to both firefighters and nearby structures.

The characteristics of a crown fire distinguish it from other types of fires, such as surface fires that primarily burn along the ground or ground fires that involve the soil and organic matter below the surface. These other types of fires are generally less intense and easier to manage compared to crown fires, which can escalate rapidly and cover large areas. Crown fires are especially prevalent in dense forested regions where tree canopies are close together, creating a pathway for fire to move from tree to tree.
