The percent area of a landscape analysis unit where the LANDFIRE Percent Low Severity (PLS) dataset predicted low severity fires and Monitoring Trends and Burn Severity (MTBS) mapped either moderate or high severity fires occurring 1984-2017.

The percent area of a landscape analysis unit where the LANDFIRE Percent Low Severity (PLS) dataset predicted low severity fires and Monitoring Trends and Burn Severity (MTBS) mapped either moderate or high severity fires occurring 1984-2017.

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 LANDFIRE Percent Mixed-Severity Fire (PMS) raster dataset (LF US_120_PMS) was combined with the Monitoring Trends in Burn Severity (MTBS) data (1984-2017) to identify areas that have experienced unnaturally severe wildfires in the recent past (1984-2017). Areas mapped are greater than 50% Mixed-Severity Fire and a high severity fire MTBS mapped fire at the same location.

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).

Identify locations that have had recent catastrophic disturbance including uncharacteristically severe wildfires resulting in needs for reforestation, landslides, or other major disturbances.

Burn severity layers are thematic images depicting severity as unburned to low, low, moderate, high, and increased greenness (increased post-fire vegetation response). The layer may also have a sixth class representing a mask for clouds, shadows, large water bodies, or other features on the landscape that erroneously affect the severity classification. This data has been prepared as part of the Monitoring Trends in Burn Severity (MTBS) project. Due to the lack of comprehensive fire reporting information and quality Landsat imagery, burn severity for all targeted MTBS fires are not available. Additionally, the availability of burn severity data for fires occurring in the current and previous calendar year is variable since these data are currently in production and released on an intermittent basis by the MTBS project.

The Monitoring Trends in Burn Severity MTBS project assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (includes wildfire, wildland fire use, and prescribed fire) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period of 1984 through 2018. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer is a vector point of the location of all currently inventoried and mappable fires occurring between calendar year 1984 and 2018 for the continental United States, Alaska, Hawaii and Puerto Rico. The point location represents the geographic centroid for the _BURN_AREA_BOUNDARY polygon(s) associated with each fire. Map Service Feature Layer
