Appalachian Ohio Appalachian Ohio is a bioregion and political unit in the southeastern part of the U.S. state of Ohio, characterized by the western foothills of the Appalachian Mountains and Appalachian Plateau. The Appalachian Regional Commission defines the region as consisting of thirty-two counties. This region roughly overlaps with the Appalachian mixed-mesophytic forests, which begin in southeast Ohio and southwest Pennsylvania and continue to north Georgia and Alabama. The mixed-mesophytic forest is found only in Central and Southern Appalachia and eastern/central China. It is one of the most biodiverse temperate forests in the world.
