The Forest Service uses a multiple-use approach to resource management to sustain the health, diversity, and productivity of the Nation’s forests and grasslands. Resource management encompasses fish & aquatic ecology, timber harvesting, non-native invasive species management, travel management, recreation sites, physical resource disciplines and more. In order to accomplish this management successfully, the Eastern Region works closely with tribal nations, public & private partners, state & local governments, and individuals. The Region encompasses 12 million acres of public land, and 40% of the U.S. population. It includes 2 million acres of wetlands; over 2,300 developed recreation sites; and approximately 16,000 miles of trails.
