The Department of the Interior (DOI) Office of Wildland Fire and USGS created the Wildfire Hazard and Risk Assessment Inventory to meet the Monitoring, Maintenance, and Treatment Plan requirements under the Bipartisan Infrastructure Law (BIL). It provides an inventory of key national, regional, and state wildfire risk and fire hazard assessments useful for understanding different characterizations of fire risk. Some of the assessments may be useful for communicating contributions toward risk reduction of treatments funded by DOI, including investments under BIL. For each assessment, the inventory provides a description and information about the spatial extent, resolution, fire modeling approach, values considered (assets and resources), and vintage of LANDFIRE and fire data used. The aggregated data can help communicate treatment application priorities to DOI landscapes. In addition, this inventory recognizes that no assessment perfectly represents all lands, as risk assessment purposes, values at risk and methodology used create variation among the assessments.
