The percent area of a landscape analysis unit where the Wildland Fire Hazard 2020 class is High and the LANDFIRE Fire Regime is Moderate.

The 2023 Wildland Hazard Potential (WHP) represents areas of significant fuel buildup. The WHP is a raster geospatial product produced by the USFS Fire Modeling Institute in the Fire, Fuel, and Smoke Program. Higher values have a higher probability of high-intensity fire, with torching, crowning, and other forms of extreme fire behavior. Data used represent areas classified as “high” or “very high” risk. The LANDFIRE Fire Regime Groups (FRG) raster dataset (LC16_BPS_200) was used to identify moderate fire regimes (Regime groups I and II). Fire regime groups represent expected historical fire regimes based on interactions between vegetation dynamics, fire spread, fire effects, and spatial context. The definitions of the regimes are outlined in the Interagency Fire Regime Condition Class Guidebook. The data for this indicator represent areas identified as having “moderate”, “high”, or “very high” wildland hazard potential within fire regime groups I and II.

The percent area of a landscape analysis unit where the Wildland Fire Hazard 2020 class is High.

The 2018 Wildland Hazard Potential (WHP) represents areas of uncharacteristic fuel buildup. The WFP is a raster geospatial product produced by the USFS Fire Modeling Institute in the Fire, Fuel, and Smoke Program. Higher values have a higher probability of high-intensity fire, with torching, crowning, and other forms of extreme fire behavior. Data used represent areas classified as �high� or �very high� hazard.

The data for this indicator represent areas identified as having high or very high wildland hazard potential and fire regime groups I and II.

The percent area of a landscape analysis unit identified as having a fire deficit by comparing modern fire occurrence (MTBS: 1984-2017) with historical fire rotations (LANDFIRE Mean Fire Return Intervals).
