Which type of fire involves the canopy fuels, such as live and dead needles and leaves?

• A. Ground fire
• B. Subsurface fire
• C. Crown fire
• D. Surface fire

Answer: (C)

Fire behavior is determined by where the fuels are located. Canopy fuels are the fuels up in the trees—the live and dead needles and leaves that make up the crowns. When fire engages these crowns, it becomes a crown fire, spreading through the treetop fuels from crown to crown and often moving rapidly with the wind. This type is typically more intense and harder to control than fires burning on the forest floor. It’s distinct from ground fires (burning organic matter in the soil), subsurface fires (burning buried materials like roots or peat below the surface), and surface fires (burning litter and vegetation on the forest floor). So, the canopied needles and leaves describe a crown fire.
