Native Range Maps

It may be impossible to know precisely the native ranges of trees before European settlement in the United States. However, the U.S. Department of Agriculture began recording native tree species distributions in the 1880s and this work continued after the Forest Service was created in 1905. Though E.L. Little’s maps were published in the 1970s, they are the culmination of this effort. These maps attempt to show species distribution when the effect of European settlement was thought to be negligible. According to Little, records of planted or introduced populations outside of continuous natural ranges, have been omitted or not knowingly included.
