Name:
Arundinaria gigantea Temporarily Flooded Shrubland Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
This alliance encompasses various temporarily flooded wetlands, including alluvial or loess substrates (streamside flats, bottomlands), dominated by Arundinaria, without an overstory, or with widely scattered trees. Evidence suggests that this alliance was widespread historically, covering large areas of many floodplains and streamsides in the Coastal Plain from North Carolina to Texas, the Mississippi River Alluvial Plain north to Illinois and Missouri, Interior Highlands, Interior Low Plateau, Southern Blue Ridge and possibly the Central Appalachians of the southeastern United States. It now occupies very little of its former acreage. Canebrakes are successional communities and may have originated following abandonment of aboriginal agricultural fields or catastrophic disturbances such as windstorms. They are thought to have been maintained in part by fires set by Native Americans. This alliance may be found along larger rivers (Buffalo, White, Norfork) in the Ozarks, as well as in the Wabash and Ohio drainage systems, at least historically. It was also reported historically along the Red and Mississippi rivers in Louisiana, Coastal Prairie rivers in Texas, and the Black, Washita, Arkansas, Pearl, Tombigbee, Yazoo, Savannah, and St. Mary's rivers. Large, extant canebrakes still exist and have been documented from the Ocmulgee Basin, south of Macon, Georgia. In the Central Appalachians various wetlands, including those on alluvial or loess substrates (streamside flats, bottomlands), were dominated by Arundinaria, without an overstory, or with widely scattered trees.
