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