The LANDFIRE (LF) Canadian Forest Fire Danger Rating System (CFFDRS) product depicts fuel types as an identifiable association of fuel elements of distinctive species, form, size, arrangement, and continuity. CFFDRS exhibits characteristic fire behavior under the specified burn conditions. In the LF 2024 Update (LF 2024) Canadian fuel models are derived from the Fuel Model Guide to Alaska Vegetation (Alaska Fuel Model Guide Task Group, 2018) and subsequent updates. The LF CFFDRS product contains the fuel models used for the Fire Behavior Prediction (FBP) system fuel type inputs. Default values assigned to the Canadian Fuel Models required to run the Prometheus fire behavior software (Prometheus, 2021) are added as attributes to the LF CFFDRS product. To designate disturbed areas where LF 2024 CFFDRS is modified, the aggregated Annual Disturbance products from 2015 to 2024 in the Fuel Disturbance layer are used. All existing disturbances between 2015-2024are represented in LF 2024 and the products are intended to be used in 2025, the year of release. When using any product from the LF 2024 fuel product suite, users should consider adjusting fuel layers for disturbances that occurred after the end of the 2024 fiscal year (after October 1st, 2024). Disturbances that occurred after the end of the 2024 fiscal year are not accounted for within LF 2024 fuel products.
