DESCRIPTION
ATBI Mapping Program: Where Do All These Species Live? – Tanner Jessel The ATBI not only focuses on scientific research and education, but also on conservation stewardship of the national park. One of the most valuable conservation questions it is answering is: Where do the thousands of species that call the Smokies "home" actually live? To date the ATBI not only has dot maps for almost all the species, but for those with enough (>30) point locations our partners at the University of Tennessee can produce "predictive models" of where they occur over the entire 800+ square mile park... an Atlas of Species!
