Editing DeWitt, Arkansas (section)

== Geography ==
DeWitt and Arkansas County are located in the Arkansas Delta (in Arkansas, usually referred to as "the Delta") a subregion of the [[Mississippi Alluvial Plain]], which is a flat area consisting of rich, fertile sediment deposits from the [[Mississippi River]] between [[Louisiana]] and [[Illinois]].

Within the Delta, Arkansas County is almost entirely within the [[Arkansas Delta#Grand Prairie|Grand Prairie]] subregion, historically a flat grassland plain underlain by an impermeable clay layer (the [[Stuttgart soil series]]). Prior to the 19th century, flatter areas with slowly to very slowly permeable soils (often containing [[fragipan]]s) supported Arkansas's largest prairie, covered in prairie grasses and forbs, with oaks covering the low hills and ridges, and pockets of floodplains with bottomland hardwood forests. This region was a sharp contrast to the bottomland forests that once dominated other parts of the [[Mississippi Alluvial Plain]]. Cropland has now largely replaced the native vegetation. Distinctively, rice is the main crop; soybeans, cotton, corn, and wheat are also grown. The rice fields provide habitat and forage for large numbers and many species of waterfowl; duck and goose hunting occurs at this important spot along the [[Mississippi Flyway]].<ref name=ark4>{{USGS|title=Ecoregions of Arkansas |comment=color poster with map, descriptive text, summary tables, and photographs |author1= Woods, A.J. |author2=Foti, T.L. |author3=Chapman, S.S. |author4=Omernik, J.M. |display-authors=etal | url=https://commons.wikimedia.org/wiki/File:Level_IV_ecoregions,_Arkansas.pdf }}</ref>
