The Appalachian Highlands Network (APHN) is one of 32 National Park Service (NPS) inventory and monitoring (I&M) networks nationwide. These networks use long-term ecological monitoring to assess the condition of park ecosystems and other significant natural resources in the parks. The goal of the I&M Program is to develop a stronger scientific basis for stewardship and management of natural resources across the National Park System.

The Network consists of four national park units occurring in two ecologically distinct physiographic regions: the Cumberland Plateau of Kentucky and Tennessee, and the Southern Appalachian Mountains of Virginia, North Carolina, and Tennessee.These parks contain some of the most diverse ecosystems within the entire National Park system, and protect the largest contiguous stands of old-growth forest remaining in the eastern United States. APHN parks range in size from 5,173 acres (Obed Wild & Scenic River) to 520,977 acres (Great Smoky Mountains National Park).

This web site delivers information about these resources and the scientific activities underway in the Appalachian Highlands Network. Learn more about what we're doing by exploring the links on the left or visit our park unit pages to find out about the resources in each of these special places.
