Cumberland Plateau
Tellico River, Unicoi Mountains, Tennessee

Cumberland Plateau Fast Facts

Where: Southeastern United States

What's at stake: Intact native hardwood forests

Threatened by: Logging to make disposable paper products

Animals include: Cougars, red-shouldered hawks, songbirds, dusky and green salamanders


bullet While shortleaf and Virginia pine are native to the Cumberland Plateau, hardwoods such as oak and hickory have long dominated the area's old-growth forests. Loblolly pine, which was introduced to the plateau in the mid-1990s by paper companies and now grows abundantly on local tree plantations, is highly vulnerable to blight.

bullet Each spring, millions of birds migrating northward from South America or the Caribbean descend on the forests of the Cumberland Plateau before pushing on to Canada's boreal forest.

bullet The hard mast acorns of the mature oak tree are a keystone resource in the Cumberland Plateau food web. As clearcut logging wipes out these nuts, hundreds of wildlife species are finding it harder to survive.

bullet The Cumberland Plateau ecosystem, which evolved undisturbed by glaciers for hundreds of millions of years, has given rise to dozens of mussel and crayfish species found nowhere else on earth.

bullet The Cumberland Plateau watershed serves as the headwaters for the Tennessee River, the Elk River, the Duck River, the Sequatchie River, the Paint Rock River and the Collins River.

bullet Researchers continue to discover new species on the Cumberland Plateau. The Cumberland dusky salamander ( Desmognathus abditus ) got its species name, "abditus" (Latin for "hidden"), because it eluded science for so long.

bullet The Cumberland Plateau region hosts the richest concentration of salamanders, including the endangered green salamander, of any temperate zone in the world.
