The Richard J. Dorer Memorial Hardwood State Forest is a 1,016,204 acres (4,112.43 km2) reserve of current and former forest in Minnesota's Driftless Area. Only 45,000 acres (180 km2) of the land is state owned, with the remainder owned by private individuals and community groups, governed by easements. Non-contiguous units are spread over seven counties ( Dakota, Fillmore, Goodhue, Olmsted, Houston, Wabasha, and Winona Counties), generally in areas just west of the Mississippi River, but extending much further west into the valleys of the Root and Zumbro Rivers.
