UFMP

Undersized Fire Mapping Project

Undersized Fire Mapping Project (UFMP) consistently maps the location, extent and severity of selected small fires occurring in the United States from 1984 to present. These fires do not meet the minimum size requirements of at least 500 acres for the eastern states and Puerto Rico and 1,000 acres for the western states, Hawaii, and Alaska for the Monitoring Trends in Burn Severity (MTBS) Program and do not occur on National Park Service (NPS) lands. Provided data are only available for fires mapped to meet other Department of Interior and Forest Service objectives within specific temporal and spatial extents. Fires less than the 500/1,000 acre MTBS threshold but occurring on NPS lands are available on the NPS Program page on the Burn Severity Portal. The UFMP and NPS burn extent and severity products are published to augment the data that are available from the MTBS Program and shared with the user community on the Burn Severity Portal. These data products complement the temporally and spatially comprehensive data provided by the MTBS Program and help support a variety of policy and resource management information needs.

Like MTBS protocols, pre- and post-fire imagery are selected to match the assessment approach based upon landscape/vegetation type. Please review the Mapping Methods | MTBS page for details on this mapping approach.
