Description

Primary humid tropical forests provide numerous global ecosystem services, but are under continuing threat of clearing from economic drivers. To facilitate national land use planning and balancing the goals of economic development and maintenance of ecosystem services, a primary humid tropical forest map was created by the UMD GLAD team. The primary forest extent was mapped for the year 2001 at a spatial resolution of 30 meters using globally acquired, free-of-charge, and consistently processed Landsat imagery.
