Canadian Forest Fire Danger Rating System (CFFDRS) depicts fuel types "as an identifiable association of fuel elements of distinctive species, form, size, arrangement, and continuity that will exhibit characteristic fire behavior under defined burning conditions". The CFFDRS arranges fuel types into five major groups with 16 discrete fuel types that are qualitatively distinguished by variations in their forest floor and organic layer, surface, and ladder fuels, and stand structure and composition.
The CFFDRS assignments for Alaska were made by fire behavior and fuels experts based on Existing Vegetation Type descriptions and representative photos.
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.
The CFFDRS product is currently produced for Alaska only.
