Created by Anantha M. Prasad and Louis R. Iverson of the USDA Forest Service, Northeastern Research Station, this site contains a great deal of information, including "distribution maps and tables for different climate change scenarios, life-history and disturbance attributes, ecological attributes, forest type maps and sorted list of species importance values by state/county for different climate change scenarios, and more for 80 [tree] species in the eastern half of the United States." While the authors have taken steps to make the atlas as easy to use as possible, the site recommends that users read the introduction and tips to avoid quickly getting lost in all the available information. After launching the atlas, users can browse by a quick species reference list or alphabetically. A sample browse on "willow" returned a life history and disturbance response fact sheet, four ecological attributes graphs or charts, eight distribution maps, and seven distribution tables. Various help and FAQ links are provided throughout the site.
