Background

The following is a partial reproduction of the discontinued web page: Digital Representations of Tree Species Range Maps from "Atlas of United States Trees" by Elbert L. Little, Jr. and other publications (https://gec.cr.usgs.gov/data/little/).

 

Maps of the ranges of tree species in North America compiled by Elbert Little, of the U.S. Department of Agriculture, Forest Service, and others (see references below) were digitized for use in USGS' vegetation-climate modeling studies. These digital map files are available here for download. Updated versions of some of these maps are also available from the U.S. Forest Service Forest Inventory Analysis program.
