Natural Features & Ecosystems

Each park unit is located in proximity to the Scioto River, Paint Creek, or the North Fork Paint Creek. Two ecoregions make up the general ecosystem for this area:
 
Paint Creek, bordering the Seip Earthworks unit, is part of the Lower Scioto Dissected Plateau ecoregion.
  • The Loamy, High Lime Till Plains ecoregion contains soils that developed from loamy, limey, glacial deposits of Wisconsinan age. These soils typically have good natural drainage. Beech forests, oak-sugar maple forests, and elm-ash swamp forests grew on the nearly level terrain in hisotric times. Today, corn, soybean, and livestock production is widespread.
  • The Lower Scioto Dissected Plateau ecoregion is rugged, dissected, and underlain by Mississippian-age shale and sandstone. It is characterized by steep ridges, high relief, and streams without acidity problems. Low gradient, broad valleys also occur. Originally, mixed oak forests and mixed mesophytic forests were widespread and bottomland hardwood forests were restricted to broad, flat-bottomed valleys. Today, the steep areas are still wooded with livestock, general, and tobacco farming occurs in less rugged areas.
