Appalachian Trail Conservancy

The Appalachian Trail Conservancy (ATC; formerly Appalachian Trail Conference) is a nonprofit organization dedicated to the conservation of the Appalachian Trail, a route in the eastern United States that runs from Maine to Georgia. Founded in 1925, the ATC is responsible for the day-to-day management of the Appalachian Trail under a cooperative agreement executed with the National Park Service. It is the lead non-governmental organization in protecting the trail's 2,193 miles (3,529 km), 250,000-acre (1,000 km²) greenway and coordinates the work of some thirty-one Appalachian Trail maintenance clubs, performing almost all of the on-the-ground maintenance work. The National Trails System Act, which established the National Trails System and brought the Appalachian Trail into the federal estate, enabled the trail to be managed as it had been since 1925, with central agency and NGO (ATC) coordination, but most trail work being performed by, in 2019, almost 6,000 volunteers.
