Landscape Fire and Resource Management Planning Tools (LANDFIRE) 20241218 LF 2023 raster digital data Sioux Falls, SD Earth Resources Observation and Science Center (EROS), U.S. Geological Survey https://doi.org/10.5066/P9BJP7OV https://www.landfire.gov Jennifer L. Long Timothy D. Hatten 2023 publication n/a US Geological Survey https://doi.org/10.3133/fs20233044 LANDFIRE’s (LF) 2023 Vegetation Departure (VDep) product categorizes departure between current vegetation condition and reference vegetation condition, according to the methods outlined in the Interagency Fire Regime Condition Class Guidebook [FRCC Guidebook (Hann et al 2010)]. VDep differs from the FRCC Guidebook, however, because it is based on the departure of current vegetation condition only, whereas the FRCC Guidebook approach includes departure of current fire regimes for the reference period. For VDep, summary units are defined as a BioPhysical Setting (BpS) with identical reference condition values regardless of map zone. For example, when a BpS is present in map zone 1, 2, 4, 5, 6 and 8, the reference conditions for this BpS are identical in map zones 1, 2, 4, 5, and 8, those map zones become a summary unit for VDep computation. Since reference conditions are unique for this BpS in map zone 6, it is a separate summary unit for calculating VDep. Within each BpS summary unit, we compare the reference percentage of each Succession Class (SClass) to the current percentage, then the smaller of the two is summed to determine the similarity index for the BpS. This value is then subtracted from 100 to determine the departure value, VDep value is always between 0 and 100, with 100 representing maximum departure. Reference conditions are derived from quantitative vegetation dynamics models that mimic native, pre-European colonization disturbance regimes. The current conditions are derived from the corresponding LF 2023 SClass data for each BpS. The proportion of the landscape occupied by each SClass, in each BpS unit, within each summary unit represents current condition of that SClass in VDep calculation. VDep is based entirely on the remaining area of each BpS unit that is occupied by valid SClasses. Each pixel in a BpS within a summary unit has the same VDep value. The LF 2023 Update (LF 2023, version 240) is the fourth update to LANDFIRE’s new base map LF 2016 Remap (version 200) and will be releasing throughout calendar year 2024. LF 2023 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 30meter 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. 2023 ground condition Complete Annually -160.6050 -154.7598 22.2719 18.8544 ISO 19115 Topic Category imageryBaseMapsEarthCover biota USGS Thesaurus fires hazard preparedness remote sensing image collections geospatial datasets geographic information systems None raster digital data Vegetation Departure VDep U.S. Geological Survey (USGS) U.S. Forest Service (USFS) LANDFIRE 2023 LF 2023 USGS Metadata Identifier USGS:673b9effd34e689449dca9a6 Common geographic areas US HI United States Hawaii None None LANDFIRE, Earth Resources Observation and Science Center (EROS), U.S. Geological Survey Customer Service Representative physical

Attributes were not validated against in person observations. The products were pixel "truth" tested for consistency of land or water characteristics across all products. Products were formally tested to ensure that valid data was produced for all pixels. Each product was then validated and tested for duplicates, omissions, and errors.

Read more about each version of LANDFIRE and its inputs at https://landfire.gov/ Beginning with the new base map of LANDFIRE 2016 Remap (LF Remap), LF products were created using recent advances in image compositing, tiling algorithms, and faster computing hardware to ensure that LF products remained relevant. LF Remap leveraged the Landsat archive, lidar data, and user contributed field plot data compiled into the LF Reference Database (LFRDB), to create new vegetation products. Reference resources utilized in LF Remap and all updates since includes but is not limited to: Forest Inventory and Analysis (FIA) program plot data, Landsat Dynamic Surface Water Extent (DSWE), the National Land Cover Database (NLCD), and National Agricultural Statistics Service (NASS). FIA DSWE NLCD NASS 20241031 For LF 2023 reference resources include but are not limited to: Monitoring Trends in Burn Severity (MTBS), Burned Area Reflectance Classification (BARC) and Rapid Assessment of Vegetation Condition after Wildfire (RAVG), PAD 3.0 for federal and protected lands identification, and a rasterized version of the Microsoft building footprint for 2022 to update developed areas. Three main submitted sources were also used: the US Bureau of Land Management (BLM), National Park Service (NPS), and the US Fish and Wildlife Service (USFWS). MTBS BAER BARC RAVG PAD Building Footprint 20241031 Disturbances in LF 2023 were also identified with LF's Remote Sensing of Landscape Change (RSLC), which identifies spectral change in vegetation using automated algorithms and image analyst review of the entire country with Landsat imagery. Burned Area (BA) data from Landsat was also used and national events (polygons) were used to identify areas and types of disturbance.
