Name:
Platanus occidentalis - (Fraxinus pennsylvanica, Celtis laevigata, Acer saccharinum) Temporarily Flooded Forest Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
Forests in this alliance occur on the fronts, terraces, and levees of small, medium and large rivers of the Atlantic Coastal Plain, Southern Ridge and Valley, Interior Low Plateau, Ozark Highlands, Ouachita Mountains, Arkansas Valley, East and West Gulf coastal plains, Mississippi River Alluvial Plain, Cumberland Plateau, Southern Blue Ridge, and lower Piedmont. These forests are dominated by Platanus occidentalis or a mixture of it with Fraxinus pennsylvanica, Celtis laevigata, and Acer saccharinum, as well as Acer negundo, Ulmus americana, Liquidambar styraciflua, Ulmus alata, Planera aquatica, Juglans nigra, Celtis occidentalis, Carya illinoinensis, Quercus nigra, Salix nigra, Carya cordiformis, Quercus pagoda, and Carya aquatica. The understory may be dense and typically contains Asimina triloba, Crataegus viridis, Crataegus spathulata, and Lindera benzoin. Herbaceous species that may be present include Elymus virginicus, Carex grayi, Carex lupulina, Carex abscondita, Chasmanthium latifolium, Boehmeria cylindrica, Polygonum virginianum, Elymus virginicus, Pilea pumila, Leersia lenticularis, and others. Vines may be abundant and species include Bignonia capreolata, Toxicodendron radicans, and Smilax tamnoides (= Smilax hispida). This alliance does not include typical alluvial forests of the upper Piedmont and Blue Ridge, but forests in this alliance may occur in these areas in restricted calcareous situations. In Arkansas, these forests occur during point bar succession as intermediates between forests dominated by Salix and Populus, and those dominated by Carya illinoinensis. In Kentucky and Arkansas, Fraxinus americana, Fraxinus pennsylvanica, Ulmus rubra, and Ulmus americana are common in these forests. According to K. Ribbeck (pers. comm.) 'Sycamore - River Birch - Silver Maple' forests of the Pearl River in Louisiana are included here.
