Description:
This bottomland forest vegetation is found in the Mississippi River Alluvial Plain of the United States and adjacent riverine areas. Stands are dominated by a combination of <i>Acer rubrum, Gleditsia aquatica</i>, and <i>Fraxinus profunda</i>. In addition, <i>Acer saccharinum, Liquidambar styraciflua, Quercus bicolor, Quercus lyrata</i>, and <i>Ulmus rubra</i> may occur as well. The shrub layer can include a diverse mixture, including <i>Cephalanthus occidentalis, Forestiera acuminata</i>, and <i>Ilex decidua</i>, but <i>Itea virginica</i> is characteristic. The herbaceous layer is usually well-developed, displaying a preponderance of plant species of bottomland habitats, including <i>Boehmeria cylindrica, Carex</i> spp., <i>Glyceria</i> spp., <i>Juncus</i> spp., <i>Laportea canadensis, Leersia</i> spp., and <i>Pilea pumila</i>. <i>Vitis</i> spp. are characteristic vines of this community, but <i>Toxicodendron radicans</i> and <i>Campsis radicans</i> are also prominent. Stands occur on the seasonally flooded bottomlands along rivers and large streams. Soils which support this forest are predominantly medium- and fine-textured, level or nearly level soils that formed in water-deposited clayey, slowly permeable, alluvial sediments in slackwater areas of floodplains. The water regime is characterized by seasonal shallow flooding, although hydrologic conditions are often extremely variable.
