Highlights from 10+ Years of Lichenological Research in Great Smoky Mountains National Park: Celebrating the United States National Park Service Centennial

A decade-long lichenological study in Great Smoky Mountains National Park has revealed a remarkable 129% increase in the park's known lichen diversity, expanding its checklist to 920 species. The research identified 54 endemic species to the southeastern U.S., 30 exclusive to the southern Appalachians, and eight found nowhere else but within the park. Nearly half of these lichens are infrequent, rare, or exceptionally rare, with some presumed extinct or near-extinct. The study also described five new lichen species, commemorating National Park Service staff, and proposed a new combination (Fuscopannaria frullaniae). By analyzing 6,000 field collections, the research delineated six regional biogeographical connections, providing insights into the park's unique lichen biota.
