Terrestrial Condition Assessment (TCA) Uncharacteristic Fire Severity Moderate (Image Service)

Direct Download (Raster Data Gateway)Objective: The TCA Uncharacteristic Disturbance Indicator identifies locations that have had recent catastrophic disturbance including uncharacteristically severe wildfires resulting in needs for reforestation, revegetation or other restoration work. Potential exists to include other major disturbances (e.g., landslides).Data: The LANDFIRE Biophysical Settings (BpS) raster datasets (LF16_BPS_200) were combined with the Monitoring Trends in Burn Severity (MTBS) data (1984-most recent) and Composite Burn Index (Parks et al. 2018) data for the year prior to the assessment year derived from NIFC Fire Perimeters (1000 ac West, 500 ac East) to identify areas that have experienced unnaturally severe wildfires in the recent past, since 1984. The CBI data serves as a bridge until MTBS data are available. The “Moderate severity” metric (layer) represents areas mapped with a dominant condition of mixed severity fire (based on BpS) but had a high severity MTBS fire in that location.Data Format: Raster data are binary: (1) “unnaturally severe fire” or (0) otherSpatial Resolution: 30mSource data: MTBS fire severity, expected fire severity , CBI methods, National Interagency Fire Center Perimeters (for CBI)Additional Resources:Details on Method Changes and Source Data VersionsOverview of the Terrestrial Condition Assessment: TCA Hubsite or Landfire Office Hour PresentationExplore the results of the most recent assessment: TCA Interactive Data ViewerLearn more about the TCA KPI: TCA DashboardThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.
