These North American Forest Dynamics (NAFD) products consist of 25 annual and two time-integrated forest disturbance maps for the conterminous United States (CONUS) derived from Landsat images for the period 1986-2010. Each annual map has classified pixels showing water, no forest cover, forest cover, no data available (data gaps) in present year, and forest disturbances that occurred in that year. The time-integrated maps are similarly classified, but over the entire 1986-2010 period with the first and last forest disturbance years identified and provided as separate maps.
The North American Carbon Program (NACP) is a multidisciplinary research program designed to obtain scientific understanding of North America’s carbon sources and sinks and of changes in carbon stocks needed to meet societal concerns and to provide tools for decision makers.
