• This map of North American Floristic Regions was based on work by Greg J. Schmidt with the University of Tennessee Botany Department.
• Original map boundaries were based on interpretation of available vegetation/floristic maps such as in Goode's world atlas, Gleason and Cronquist's Plant Geography, and Bailey's ecoregions.
• Map boundaries were adjusted based on forest cover type data available at the National Atlas.
• THIS IS NOT AN EXACT SCIENCE! For example, small populations of Boreal Forest species can be found at High Elevations in the Appalachians. They are not represented on this "painted" map. The intent is to provide GENERAL information, and (hopefully) aid end users with their tree identification needs.
