Modifications of the Upper Mississippi River and their effects on floodplain forests


Publication Date


The natural Upper Mississippi River (UMR) and its tributaries flowed and meandered freely across large floodplain landscapes. Processes such as flooding, erosion, and sedimentation were powerful natural forces that shaped and maintained some floodplain forest communities. Beginning in the early nineteenth century, the UMR and its floodplain have been modified by navigation structures and agriculture. As a consequence of human modifications, a large portion of the UMR floodplain is no longer periodically inundated and the hydrologic patterns in the river, as well as on the floodplain, have changed. In general, agriculture and urban development have greatly reduced floodplain forest acres, especially in river reaches where a mainline [...]
