Fuel Vegetation Type (FVT) represents a modified version of Existing Vegetation Type (EVT). FVT more accurately leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation. Linking disturbed areas to pre-disturbance EVTs allows fuel model transition assignments to properly align with logic developed from Fuels Calibration Workshops, giving more accurate representations during fire behavior analysis.
FVT was developed using the full suite of LANDFIRE (LF) vegetation releases and the most recent ten years of Annual Disturbance products.
LF uses FVT in the development of the fuel layers.
