What are the three types of ground cover fires?

• A. Ground, Surface, Crown
• B. Ground, Subsurface, Aerial
• C. Surface, Crown, Subsurface
• D. Ground, Surface, Subsurface

Answer: (A)

Fire behavior is organized by where the fuel is located in the landscape: ground, surface, and crown. Ground fires burn organic matter buried in or beneath the soil, such as peat, duff, or roots; they often smolder for long periods and are hard to detect. Surface fires consume fuels that sit on or near the surface, like leaf litter, grasses, and fallen branches; they usually spread more slowly and are generally easier to control than canopy fires. Crown fires leap into the tree canopies and race through the treetops, driven by wind and ladder fuels, and they’re the most dangerous and difficult to suppress. Since these three categories—ground, surface, and crown—cover the typical places fuels burn, they are the best way to describe the three types of fire by fuel location. Subsurface or aerial terms aren’t the standard trio for this concept, so they don’t fit as neatly.
