The U.S. Forest Change Assessment Viewer is the interactive map component of the USFS program, ForWarn II. ForWarn II is a vegetation change recognition and tracking system that uses moderate resolution satellite (MODIS) data. It provides near real-time change maps for the continental United States (CONUS). Changes detected can inform your management decision to prepare for what the future might hold with disturbances looming nearby such as development, or insect outbreaks, etc. Access more information, a user guide reference to this resource, and help videos put out by the ForWarn program team.
