Which kind of fuel includes brush up to 6 feet?

• A. Subsurface fuels
• B. Surface fuels
• C. Aerial fuels
• D. Ground fuels

Answer: (B)

Fuels are classified by where they sit relative to the ground to help predict fire spread and choose tactics. Surface fuels include what lies on the ground or just above it—like grasses, leaf litter, and shrubs within reach of a ground fire. Brush up to about six feet fits here because it’s part of the ground-level layer, not in the tree canopy or buried underground. Aerial fuels are higher up in the crowns of trees or tall brush, subsurface fuels are buried below the surface (roots and deep organic matter), and ground fuels refer to material within or right at the soil surface. So brush within that six-foot range is categorized as surface fuels, guiding the approach to suppressing and managing surface fires.
