Ohio Environmental Statistics and Indicators -
Land/Habitat/Natural Resources


Ohio is a state with some distinct regional land use patterns. Agricultural land use is centered in the northwest; rolling hills and woodlands are in the southeast; and the major metropolitan areas are in the northeast, central and southwestern parts of the state.

Indicators about land use are not the only information presented in the table below. Also included are indicators for activities that are land-based, such as recreation and agriculture. In addition, some statistics relevant to wildlife habitat are presented below because habitat is a type of land use.
