The Appalachian Mountains are among the oldest in the world, having changed relatively little over the past 200 million years. The Southern Appalachians, where the land was never covered by glaciers or inundated by oceans, are one of the most species-rich temperate areas in the world, with 2,250 species of vascular plants, over 130 species of trees, more than 200 species of birds, and thousands of species of invertebrates.
This ecoregion is also recognized as a world center for amphibian, plant, and aquatic species diversity. Network parks protect the largest contiguous stands of old-growth forest remaining in the eastern United States, as well as many of the best remaining examples of globally imperiled species populations and communities.
