      <abstract>The LANDFIRE Preliminary Annual Disturbance (PDist) product was first introduced with the LF 2023 Update (LF 2023). While Limited Annual Disturbance (LDist) is a first “draft”, PDist is akin to a second “draft” of the LANDFIRE Annual Disturbance product and includes disturbance events captured between October 1, 2024 and September 30, 2025. PDist releases for the Conterminous United States (CONUS), Alaska (AK), Hawaii (HI), and Puerto Rico and the US Virgin Islands (PRVI) will be ongoing throughout the 2026 calendar year. 

PDist was derived from NASA/USGS Harmonized Landsat Sentinel-2 (HLS), submitted disturbance events from the data call, and online fire program data collected on or before September 30, 2025. Unlike the LDist product released earlier in calendar year 2026, PDist includes remotely sensed severity for submitted events and unknown disturbances where change was detected. </abstract>
      <purpose>The LANDFIRE 2025 Update (LF 2025, version 2.6.0) is the sixth update to the LF 2016 Remap base map (version 2.0.0) and will be releasing throughout calendar year 2026.   

LF 2025 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. </purpose>
      <supplinf>Ongoing since LF 2016 Remap AK products have included a 90km buffer area into Canada.</supplinf>

        <procdesc>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).</procdesc>

        <procdesc>For LF 2025 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). Then the Protected Areas Database of the United States (PAD) was used to remove agriculture on non-irrigated federal and state protected lands. A rasterized version of the Microsoft building footprint and Wildfire Risk to Communities (WRC) was used to update developed areas. Two main submitted sources were also used: the US Bureau of Land Management (BLM) and National Park Service (NPS). </procdesc>

Burned Area (BA) data from Landsat was also used and national events (polygons) were used to identify areas and types of disturbance.</procdesc>
