More species of fungi exist in North Carolina than anywhere else in the country. In the Great Smoky Mountain National Park, 10,000 species are identified, but scientists estimate another 90,000 remain unidentified. In the year 2000, a survey began to identify all the park's fungi. Other teams will map and identify everything from the park's viruses to mammals. When the project is completed in fifteen years, park managers will have the first comprehensive assessment of the Smoky Mountains' biodiversity.
