WFEIS Fuels Map







The Fuel Characteristic Classification System


The Fuel Characteristic Classification System (FCCS; http://www.fs.fed.us/pnw/fera/fccs/) was developed by the US Forest Service to provide a comprehensive description of the vegetation available for burning during a fire.

The FCCS is both a conceptual framework and a software tool for quantifying fuels over spatial domains from a few square meters to many square kilometers.

Unlike fire-behavior fuel models, whose purpose is to provide parameters useful for predicting fire behavior and fire spread, the FCCS specifies vegetation composition and fuel loading of live and dead fuels, which are easily connected to remotely sensed vegetation types (McKenzie et al. 2007).

The FCCS fueldbed descriptors provide details on fuel structure and loading (density) by vertical strata (Figure 1), providing data that have relevance for both emissions and basic fire behavior.


FCCS Maps


Standard FCCS fuelbeds represent fuels across the US and Mexico. They were compiled from scientific literature, fuels photo series, fuels inventories, and expert opinion. Allometric equations in the FCCS calculator produce fuel loadings, other plot-level metrics, and fire-hazard potential. FCCS standard fuelbeds used within WFEIS have been mapped at a 1-km grid-scale for CONUS and Alaska from a 30-m grid-scale product produced under the Landfire Project (http://www.landfire.gov/).


Integrated Wildland and Cropland 30-m Fuel Characteristics Map for the US



An extended version of the CONUS fuels map was created to integrate cropland burning into WFEIS. The product is a 30-m comprehensive fuelbed characteristics map for both the wildland and cropland areas of the conterminous United States (CONUS) for 2010. This integrated product is the result of combining the spatially discrete Fuel Characteristic Classification System (FCCS) data of the US Forest Service (USFS) with the crop- and grassland-specific information from the US Department of Agriculture’s Cropland Data Layer (CDL).

In WFEIS, this map was used to derive two upscaled 1-km products: (a) a cropmask (for delineating between natural and cropland fuels) and (b) a cropland fuels map. The pixel values for the 1-km cropland fuels maps used in WFEIS are 12-digit codes indicating the top three most common 30m agricultural fuelbeds and their corresponding percent cover within the 1-km pixel.
