This page includes a general description of the product, please consult the schedule and version pages for information specific to each release.
The LANDFIRE (LF) fuels vegetation products describe the elements of fuels vegetation for each LF vegetation production unit. Fuel Vegetation Type (FVT) represents a modified version of Existing Vegetation Type (EVT). FVT more accurately leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation. Linking disturbed areas to pre-disturbance EVTs allows fuel model transition assignments to properly align with logic developed from Fuels Calibration Workshops, giving more accurate representations during fire behavior analysis.
FVT was developed using the full suite of LF vegetation releases and the most recent 10 years of Annual Disturbance products. The FVT product is then evaluated through a series of QA/QC measures ensuring lifeform of the vegetation type assignment matches the lifeform of associated FVT layers.
Beginning with LF 2016 Remap, and beyond, an improvement for fuels products in disturbed areas was implemented. Fuels are now adjusted to expected current year vegetation conditions for disturbances that have occurred between certain select years that vary by the version. Making the fuels products “capable to X year fuels” or “capable fuels”.
LF 2016 Remap and beyond includes a 90-kilometer buffer along the 1,500 miles of the eastern and southern borders AK shares with Canada. Then with the LF 2020 update, and future updates, for the Conterminous United States (CONUS) a 90-kilometer buffer into Mexico is also included.
LF uses FVT in the development of the fuel products.
