LANDFIRE 2020 Fuel Disturbance (FDist) CONUS
LANDFIRE (LF) disturbance products are developed to provide temporal and spatial information related to landscape change. LF 2020 Fuel Disturbance (FDist) uses the latest Annual Disturbance products from the effective disturbance years of 2012 to 2020. In LF 2020, fuel products were created with LF 2020 vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas using fuel rule sets. FDist is created from LF 2020 Historical Disturbance (HDist) by grouping similar disturbance types, which represent disturbance scenarios within the fuels environment.
Beginning with LF 2016 Remap, refinements to the FDist process enabled the creation of pre-disturbance fuel vegetation within disturbed areas. This approach facilitated 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”. This process considers all the existing disturbances included in LF 2020 and assigns fuels to the pre-disturbance vegetation based on the adjusted TSD, making the products "2022 capable fuels" intended for use in 2022 and accounting for two years of disturbance recovery. By synchronizing TSDs for surface and canopy fuels, these refinements improve performance of fire behavior modeling. Learn more about LF 2020 at https://landfire.gov/data/lf2020
