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). The LANDFIRE Biophysical Settings (BpS) raster datasets (LF16_BPS_200) were combined with the Monitoring Trends in Burn Severity (MTBS) data (1984-assessment year) 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 (1984-assessment year). The CBI data serves as a bridge until MTBS data are available. The Moderate Severity variable represents areas mapped with a dominant condition of mixed-severity fire and had a high severity MTBS fire pixel in that location.
