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.
Annual Disturbance products were first incorporated into fuel production during LF 2008. The introduction of this information allowed for informed changes to the assigned fuel models from disturbance type, severity, and time since the disturbance.
LF Remap incorporates Fuel Vegetation Type, Fuel Vegetation Cover, and Fuel Vegetation Height in place of EVT, EVC, and EVH in fuel model assignment. The fuel vegetation products represent vegetation that existed prior to disturbance for disturbed areas and EVT at non-disturbance locations. The pre-disturbance scenario is represented by the vegetation that existed before the event occurred. The assignments of fuel models are informed by pre-disturbance vegetation and type, severity, and time since disturbance.
The FBFM13 product can serve as input to wildland fire prediction models.
LF Remap FBFM13 has "capable fuels" functionality, meaning FBFM13 is assigned using FDist capable fuels.
The comma separated value (CSV) file used for the raster attribute table is included in the LF product download in database file (DBF) format.
(Why is the CSV important?)
