These original 13 standard fire behavior fuel models serve as input to Rothermel's surface fire behavior and spread model. LANDFIRE's (LF) 13 Anderson Fire Behavior Fuel Model (FBFM13) represents distinct distributions of fuel loading found among surface fuel components (live and dead), size classes, and fuel types. The fuel models are described by the most common fire-carrying fuel type (grass, brush, timber litter, or slash), loading and surface area-to-volume ratio by size class and component, fuelbed depth, and moisture of extinction.
FBFM13 was evaluated through a series of workshops held across the nation with fire and fuels specialists.
LF 2008 first incorporated Annual Disturbance products into fuel production. The introduction of this information allows for informed changes to the assigned fuel models from disturbance type, severity, and time since the disturbance.
For LF Remap, Fuel Vegetation Type (FVT), Fuel Vegetation Cover (FVC), and Fuel Vegetation Height (FVH) are incorporated in place of EVT, EVC, and EVH in fuel model assignment.
The FBFM13 product can serve as input to wildland fire prediction models.
