LANDFIRE Remap Fuel Disturbance (FDist) Palau

LANDFIRE (LF) disturbance products are developed to provide temporal and spatial information related to landscape change. LANDFIRE 2016 Remap (LF Remap) Fuel Disturbance (FDist) uses the latest 10 years of Annual Disturbance products from the effective disturbance year. FDist is a refinement of past LF versions and is created from Remap historical Disturbance (HDist) by grouping similar disturbances types, which represent disturbance scenarios within the fuels environment. LF Remap contains refinements to the FDist process enabling the creation of pre-disturbance fuel vegetation within disturbed areas. the new approach facilitates the production of capable fuels products, such as FDist. The capable fuels process calculates Time Since Disturbance (TSD) assignments for disturbed areas using an "effective year". Year 2020 fuels, for example, may be calculated for the year 2020. the new process considers all the existing disturbances included in LF Remap and assigns fuels to the pre-disturbance vegetation based on the adjusted TSD, making the products "2020 capable fuels." By synchronizing TSDs for surface and canopy fuels, these refinements improve performance of fire behavior modeling. LF Remap fuel products in areas mapped as disturbed within the past 10 years are delivered with the capable fuels functionality.
