The park's ongoing All Taxa Biodiversity Inventory (ATBI) conducted by Discover Life in America has now tallied 7,391 types of plants and animals that were previously not known to exist in the Smokies. Of these, 922 are new to the science books. This brings the list of total known species in Great Smoky Mountains National Park to 17,797, an incredible diversity of life for an 800 square mile area!
