Great Smoky Mountains National Park: Fire Fuel Modeling

GIS OverlayThe GRSM vegetation mapping project was extended to include fire behavior fuel  modeling for the entire park. Working in  conjunction with fire experts at GRSM, fuel classes based on U.S.Department of Agriculture (USDA) publication, “Aids to Determining Fuel Models for Estimating Fire Behavior”, INT-122, by H.E. Anderson, 1982, were developed for eastern deciduous forest.  A rule-based model was then created that  determines the fuel class from overstory and understory vegetation databases. The resulting fire behavior fuel class maps/data sets will be used for fire management applications in GRSM.
