The Wabash Bottomlands ecoregion is found along the lower Wabash and Ohio rivers. Ecoregion 72a contains the most pronounced Mississippian-type biotic assemblage in Indiana and, historically, significant numbers of waterfowl have wintered here. The low, nearly level flood plains, terraces, and bayous are composed of alluvial and outwash deposits; they were seasonally inundated before flood control and were once covered by bottomland hardwood forests. Today, some woodland remains but, mostly, the land is used for corn, soybean, wheat, alfalfa, or livestock farming; poor drainage and droughtiness are critical factors controlling land use.
