The purpose of this paper is to document how to make changes to the Alaska 2009 fuels layer to account for recent fires. A similar process can be followed next year to modify the LANDFIRE National '2010' LCP using the 2009 final fire perimeters as well as the masks described below. Likewise, other LCP layers (e.g., canopy cover, stand height) can be modified using a variety of non-fire masks (e.g., beetle-killed areas, detailed vegetation mapping).
