Objective:<\/span><\/span> 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).<\/span><\/span><\/p>

Data:<\/span><\/span> 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 \u201cLow severity\u201d metric (layer) represents areas mapped with a dominant condition of low severity fire (based on BpS) but had a moderate or high severity MTBS fire in that location.<\/span><\/span><\/p>
