Long Timothy D. Hatten 2023 publication n/a US Geological Survey https://doi.org/10.3133/fs20233044 LANDFIRE's (LF) 2001 Update forty Scott and Burgan Fire Behavior Fuel Models (FBFM40) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Scott & Burgan 2005). The fuel models are described by the most common fire carrying fuel type (grass, grass/shrub, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. FBFM40 contains more fuel models for every fuel type than 13 Anderson Fire Behavior Fuel Models (FBFM13) and the number of fuel models representing relatively high dead fuel moisture content is increased. In FBFM40 fuel models with an herbaceous component are dynamic, to simulate curing, rather than remaining constant. To create the FBFM40 product, expert rulesets were developed to understand how different types of disturbance would change pre-disturbance fuel models to post disturbance fuels, based on the severity and time since disturbance. These rulesets are represented in the LF Total Fuel Change (LFTFC) Tool and Database for both disturbed and non-disturbed areas. The LANDFIRE (LF) 2001 (version 1.0.5) Refresh of the LF National Base Map is the foundational version of LANDFIRE. The initial data released by LANDFIRE, referred to as LANDFIRE (LF) National (version 1.0.0), was completed in the winter of 2010. LF 2001 released in 2011 and incorporated improvements as well as remodeled cover and height layers. LF 2001 also ensured wildland fires through 2001 were represented. When LF 2001 released, it superseded LF National as the revised base map. LF 2001 products are designed to facilitate national and regional level strategic fire and resource management planning and reporting of management activities. The principal purposes of the products include providing: 1) national level landscape scale geospatial products to support fire and fuels management planning and 2) consistent fuels products to support fire planning, analysis, and budgeting to evaluate fire management alternatives. Products are created at a 30-meter raster; however, the applicability of products varies by location and specific use. LF products were designed to support 1) national (all states) strategic planning, 2) regional (single large states or groups of smaller states), and 3) strategic/tactical planning for large sub regional landscapes and Fire Management Units (FMUs) (such as significant portions of states or multiple federal administrative entities). The applicability of LF products to support fire and land management planning on smaller areas will vary by product, location, and specific use. Managers and planners must evaluate LF products according to the scale and requirements specific to their needs. 2001 ground condition Complete None planned -179.3173 -122.0000 71.5478 48.8767 ISO 19115 Topic Category imageryBaseMapsEarthCover biota None raster digital data U.S. Geological Survey (USGS) U.S. Forest Service (USFS) LANDFIRE 2001 LF 2001 Scott and Burgan Fire Behavior Fuel Model FBFM40 Fire Behavior Fuel Model 40 FBFM USGS Thesaurus fire hazard preparedness remote sensing image collections geospatial datasets geographic information systems USGS Metadata Identifier USGS:68cac619d4be026a9943a5ab Common geographic areas AK Alaska United States OCONUS None These data are marked with a Creative Common CC0 1.0 Universal License.
