Great Smoky Mountains National Park - host to biological diversity

The Great Smoky Mountains National Park is known for its biological diversity with over 10,000 documented species of plants and animals. The Smokies have such a great diversity because of the range in altitude, the abundant rainfall and glaciers that invaded the continent over 10,000 years ago. These glaciers didn’t reach as far south as the Smoky Mountains, and many species from farther north found refuge here.

The Great Smoky Mountains National Park has been designated an International Biosphere Reserve by the United Nations.
