Fuel Characteristic Classification System Fuelbeds

Fuel Characteristic Classification System (FCCS) defines a fuelbed as the inherent physical characteristics of fuel that contribute to fire behavior and effects (Riccardi and others 2007). A fuelbed can represent any scale or precision of interest. In FCCS, fuelbeds represent the structure and composition of wildland fuels and can accommodate a wide range of fuel characteristics in six horizontal fuel layers called strata (Ottmar and others 2007).

FCCS summarizes and classifies wildland fuel characteristics and can also be used to predict surface fire behavior, crown fire potential and available fuel for estimating consumption, fire effects, and emissions.

The fundamental component of the FCCS, the fuelbed, is the mapping unit in the FCCS. The LF FCCS is delivered with attributes summarized from the FCCS calculator for each fuelbed, including name and fuel loading information in tons per acre. This information can be used for fire behavior and fire effects estimations.

Consume Input Tables are formatted for use in the Consume 4.2 calculator embedded in the FFT software. Fuel loading units are in tons per acre and can be used in the command line version of Consume. This table can be used in conjunction with the FCCS in a mapping program.

First Order Fire Effects Model (FOFEM) Input Tables provide fuel loading values summarized for use in the general FOFEM calculator. The file is not formatted for use in the FOFEM batch feature in the program. Fuel loading units are tons per acre and with additional fuel moisture and site descriptors this file can be adapted to work in the FOFEM batch function. This table can be used in conjunction with the FCCS in a mapping program.

FCCS is planned to be produced for LF Remap. Production will occur after fuels production and will be released as part of the final release for CONUS.

(Why is the CSV important?)
