More than any other area in the state, farming has changed this region most severely. This region comprises a small corner of southwest Ohio. Water quality impairments in the western section are mostly due to farming.
Rural land is used for crop land, pasture, livestock and forest lands.
This is a large swath of land area in central and western Ohio. It is an area of extensive crop land agriculture without the extensively developed, heavy industrial centers of the Erie Ontario Lake Plain. This is Ohio's unglaciated heavily-forested central and southeastern corner. This region contains the highest elevations in Ohio. Coal mining and timber harvesting are among the major land uses with some agriculture on the valley floors.
