More than 80 percent of the eastern aspen cover type grows on 13 million acres of commercial forest land in the Great Lakes region. Soils range from well-drained sands to poorly-drained clays. This forest type, characterized by gentle topography, humid, warm summers, and cold, continental winters, is being studied in Minnesota, Michigan, and Wisconsin through the LTSP efforts of the Forest Service's North Central Research Station and the Eastern Region.
