Name: Fraxinus pennsylvanica - Ulmus americana - Celtis laevigata / Ilex decidua Floodplain Forest
Reference: NatureServe Biotics 2019
Description: This green ash - American elm - sugarberry community is found throughout the central and southern United States. Stands occur in floodplains of major rivers where water is absent for most of the growing season. Soils are moist alluvial clay or silt loams. <i>Ulmus americana</i> was once the most prominent member of this forest, but Dutch elm disease (<i>Ceratostomella ulmi</i>) and logging have eliminated many of the largest mature <i>Ulmus</i> spp. from most of the species natural range. <i>Fraxinus pennsylvanica</i> dominates on moist flats and shallow sloughs, while <i>Celtis laevigata</i> is most prevalent on new land or front sites. Other species commonly encountered include <i>Carya aquatica, Quercus lyrata, Liquidambar styraciflua</i>, and <i>Acer negundo</i>. The subcanopy is often dense and dominated by <i>Fraxinus pennsylvanica</i> which sprouts prolifically. Shrubs typical of this forest include <i>Cornus drummondii, Ilex decidua</i>, and <i>Crataegus</i> spp. The herbaceous layer is dense and diverse, dominated by <i>Galium</i> spp., <i>Viola</i> spp., <i>Carex</i> spp., <i>Leersia</i> spp., <i>Boehmeria cylindrica, Laportea canadensis, Pilea pumila, Impatiens capensis</i>, and <i>Impatiens pallida</i>. Vines most often encountered include <i>Toxicodendron radicans, Campsis radicans</i>, and <i>Parthenocissus quinquefolia</i>.
