Where U.S. Forests are Located, Official USFS Forest Occurrence Map

This forestland occurrence  map indicates where the largest concentration of  individual trees are growing (based on existing growing stock) in the U.S. by county and state. The lighter green map shade means less tree densities while darker green means more tree densities. No color means very few trees.

The United States Forest Service's Forest Inventory and Assessment group developed this map to show the spatial distribution of the nation's forest land in 2007 as a percentage of county land area and county tree density.
