Active Alerts
LANDFIRE’s 2025 Update has arrived with the release of the Limited Annual Disturbance (LDist) 2025 products for all extents.
Historical Disturbance (HDist) has been retired for all versions. It is still available by special request via Help Desk.
LANDFIRE is updating product file naming conventions throughout the month of January. The unicode (3-digit identifier) previously used in LANDFIRE product names will be removed; products will now be named using only the version, product name, and extent (example: LF2024_EVT_CONUS). For more information on naming conventions, visit the LANDFIRE Naming Conventions page.
Errors impacting LF 2024 Disturbance Severity in the Southeast GeoArea of CONUS have been identified. In some areas, disturbances labeled as "Weather" (i.e., hurricane-damage disturbances) were incorrectly labeled as "No Severity". LANDFIRE will be releasing corrected LF 2024 products on LANDFIRE.gov as soon as possible, with an estimated timeframe of early 2026. More details can be found here.
LANDFIRE has released the final data sets for the LF 2024 Update (LF 2024), including Vegetation, Fuel, and Disturbance products for Hawaii and Puerto Rico and the US Virgin Islands. The final products for Alaska (SClass, VCC, and VDep) have also been released.
As LANDFIRE prepares for an overhaul of naming conventions, some versions and data have been retired or are temporarily unavailable. MoD-FIS products have been temporarily removed and will be available again in the early spring. LF 2001 and LF 2020 have been retired but are still available by request or in the USGS ScienceBase library. The following LF 2020 products will remain available across all distribution platforms: BPS, Topographic product suite, and all LF 2020 applicable Annual Disturbance years.
LANDFIRE (LF) has released LF 2024 Update (LF 2024) NC, SC, NE, and SE fuels, vegetation, and Historical Disturbance products. Additionally, the SW and NW GeoAreas have also been updated. We highly encourage everyone to re-download all fuel products for any GeoArea within CONUS as new events have been incorporated (insect and disease) since the SW and NW releases. This completes the full Conterminous United States (CONUS) for the LF 2024 Update.
Seasonally adjusted FBFM40 for Fall MoD-FIS has also been released.
The last products for LF 2024, within the areas Hawaii and Puerto Rico and the US Virgin Islands, will release in November.
