Surface fuels refer to flammable materials located at what height?

Surface fuels encompass flammable materials that are typically found at ground level up to approximately 6 feet in height. This definition aligns with how fire behavior is influenced by the characteristics of fuels present near the ground, where flames can easily ignite and spread.

Fuel sources within this range include grasses, leaves, shrubs, and smaller trees, which can have a significant impact on fire dynamics. When these materials ignite, the fire can produce flames that may extend upwards, contributing to the intensity and spread of the fire. Understanding the positioning of surface fuels is critical for fire investigation and management, as it helps in assessing fire risks, predicting fire behavior, and implementing effective firefighting strategies in various environments.
