NCRS - The Changing Midwest Assessment

The North Central Region is comprised of 28 Forest Type Groups. The Oak/Hickory, Maple/Beech/Birch , Aspen/Birch, Elm/Ash/Cottonwood , and Spruce/Fir are the most common Forest Type Groups in the Region.

This slide show is comprised of maps that depict how the total number of acres of forest in the Region changed from roughly 1980 to 2000.

Forest is defined as a tract of land of at least 1 acre, at least 120 feet wide, and at least 16.7 percent stocked with forest trees of any size. An example of minimum stocking would be 15 seedling/saplings per acre.
