The Great Smoky Mountains National Park and its non-profit partner, Discover Life in America (DLIA), recently celebrated the 20th year of the All Taxa Biodiversity Inventory (ATBI) with the announcement of a major milestone of the project - 1,000 new species to science! Over the past 20 years, many species have been documented in the park for the first time, but the number of species discovered that are completely new to science - meaning they haven’t been documented anywhere on Earth before - is truly amazing. The most recent additions come from the work of lichenologists Erin Tripp, of the University of Colorado, and James Lendemer, of the New York Botanical Garden, who have added five more new-to-science species to the tally, bringing the total up to 1,000. The past 10 years of their research, which is a part of the overall ATBI project, has increased the parks knowledge of its lichen fauna by 130% over the original diversity estimates. The five new lichens were named to commemorate NPS staff who played a role in their work. In 1998, the park and DLIA formed a partnership to conduct the ATBI to discover and understand all the species that inhabit the park’s 522,000 acres, including plants, fungi, millipedes, crayfish, tardigrades (water bears), worms, insects, and many other groups. The project involves cooperating scientists from all over the US and abroad, park staff, students, and volunteer “citizen scientists.” Overall, the ATBI has more than doubled the number of species known to the park, from about 9,300 historic species records to 19,866 species known to the park today. The ATBI research provides crucial information for park managers and leads to a better understanding of ecosystem function and how it is dependent on biodiversity. The project involves students of all ages in the process of discovery, which ultimately inspires them to be the next generation of park stewards.
