Fuel Vegetation Cover (FVC) represents a modified version of Existing Vegetation Cover (EVC). LANDFIRE (LF) Remap EVC is mapped as continuous estimates of canopy cover for tree, shrub, and herbaceous lifeforms with a potential range from 0-100 percent. To translate continuous EVC values into fuel model assignments, EVC values were binned to correspond with the bins for previous LF versions.
FVC was developed using the full suite of LF vegetation releases and the most recent ten years of disturbance data. FVC more accurately leverages fuel transition assignments related to disturbed areas to properly align with logic developed from Fuels Calibration Workshops.
LF uses FVC in the development of the fuel layers.
