Long Timothy D. Hatten 2023 publication n/a US Geological Survey https://doi.org/10.3133/fs20233044 LANDFIRE's (LF) 2001 thirteen Anderson Fire Behavior Fuel Models (FBFM13) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Anderson 1982). The fuel models are described by the most common fire carrying fuel type (grass, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. LF FBFM13 can be used for fire spread related characteristic models. To create the FBFM13 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. 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 When LF 2001 released, it superseded LF National as the revised base map.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 Anderson Fire Behavior Fuel Model FBFM13 FBFM Fire Behavior Fuel Model 13 USGS Thesaurus fire hazard preparedness remote sensing image collections geospatial datasets geographic information systems USGS Metadata Identifier USGS:68c9c31ad4be0274ff4b388f Common geographic areas AK Alaska United States OCONUS None These data are marked with a Creative Common CC0 1.0 Universal License.

LF 2001 FBFM1 Surface fires that burn fine herbaceous fuels, cured and curing fuels, little shrub or timber present, primarily grasslands and savanna. LF 2001 FBFM2 Burns fine, herbaceous fuels, stand is curing or dead, may produce fire brands on oak or pine stands. LF 2001 FBFM3 Most intense fire of grass group, spreads quickly with wind, one third of stand dead or cured, stands average 3ft tall. LF 2001 FBFM4 Fast spreading fire, continuous overstory, flammable foliage and dead woody material, deep litter layer can inhibit suppression. LF 2001 FBFM5 Low intensity fires, young, green shrubs with little dead material, fuels consist of litter from understory. LF 2001 FBFM6 Broad range of shrubs, fire requires moderate winds to maintain flame at shrub height, or will drop to the ground with low winds. LF 2001 FBFM7 Foliage highly flammable, allowing fire to reach shrub strata levels, shrubs generally 2 to 6ft high. LF 2001 FBFM8 Slow, ground burning fires, closed canopy stands with short needle conifers or hardwoods, litter consists mainly of needles and leaves, with little undergrowth, occasional flares with concentrated fuels. LF 2001 FBFM9 Longer flames, quicker surface fires, closed canopy stand of long-needles or hardwoods, rolling leaves in fall can cause spotting, dead-down material can cause occasional crowning. LF 2001 FBFM10 Surface and ground fire more intense, dead-down fuels more abundant, frequent crowning and spotting causing fire control to be more difficult. LF 2001 FBFM11 Fairly active fire, fuels consist of slash and herbaceous materials, slash originates from light partial cuts or thinning projects, fire is limited by spacing of fuel load and shade from overstory. LF 2001 FBFM12 Rapid spreading and high intensity fires, dominated by slash resulting from heavy thinning projects and clearcuts, slash is mostly 3 inches or less. LF 2001 FBFM13 Fire spreads quickly through smaller material and intensity builds slowly as large material ignites, continuous layer of slash larger than 3 inches in diameter predominates, resulting from clearcuts and heavy partial cuts, active flames sustained for long periods of time, fire is susceptible to spotting and weather conditions.
