The USDA Forest Service’s system of Experimental Forests and Ranges provides an incredible wealth of records and knowledge of environmental change in natural and managed forest and rangeland ecosystems across the United States. The present system of 78 Experimental Forests and Ranges has been established progressively since 1908; many sites are more than 50 years old. The system provides places for long-term science and management studies in major vegetation types of the 195 million acres of public land administered by the Forest Service. Individual sites range from 47 to 22,500 ha in size.

This is a map showing the location of the Experimental Forests and Ranges. The map also provides a brief chronology of the program and a description for some of these forests and ranges.
