Anderson's (1982) fire-behavior fuel models were assigned to unique combinations of PVT, cover type, size class, and canopy density based upon field experience of U.S. Forest Service and Bureau of Land Management ecologists. These data were designed to characterize mid-scale patterns across Idaho of fuels models for assessing both the relative wildland fire risk and relative wildland fire hazard. They were developed specifically for use in characterizing relative wildland fire hazard which was then used to assess the risks of wildland fire to communities. This dataset was used in the "Idaho Interagency Assessment of Wildland Fire Risk to Communities, 2007" to derive NFFL Fuel Model - Map 3 . It was created for the Statewide Interagency National Fire Plan Working Group to which the Bureau of Land Management (BLM), Idaho is a member. It has also been used in other BLM planning efforts such as Resource Management Plans, Fire Management Plans, and NEPA analysis. General Limitations These data were designed to characterize mid-scale patterns across the state of Idaho at a scale of approximately 1:100,000. The use of these data at scales less than 1:100,000 is not recommended without field verification. Although the resolution of this theme is a 90-m cell, the expected accuracy does not warrant its use for geographic extents smaller than approximately 10,000 acres. That is, these data were not designed to be used for "project level" assessments that typically require 1:24,000 scale data.
