CEGL007999 Platanus occidentalis - Betula nigra - Celtis laevigata - Fraxinus pennsylvanica / Arundinaria gigantea Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Sycamore - River Birch - Sugarberry - Green Ash / Giant Cane Floodplain Forest
Colloquial Name: Ozark Sycamore - Ash - Sugarberry Floodplain Forest
Hierarchy Level: Association
Type Concept: This sycamore - ash - sugarberry bottomland forest occurs on broad floodplains of large rivers in the Ozarks of Arkansas (e.g., White River), possibly ranging into the Arkansas River Valley and Ouachita Mountains. The deep, alluvial soils are highly permeable, and the hydrology is flashy. The forest canopy has no clear dominant but is composed of a mixture of characteristic bottomland hardwood species. Canopy species documented from a single site along the White River include Betula nigra, Celtis laevigata, Fraxinus pennsylvanica, Gleditsia triacanthos, Juglans nigra, Platanus occidentalis, Populus deltoides ssp. deltoides, Ulmus rubra, and Ulmus americana. Subcanopy trees include Acer negundo, Catalpa bignonioides, Maclura pomifera, and Ulmus alata. Arundinaria gigantea forms dense patches in the understory. Other shrubs include Lindera benzoin and Symphoricarpos orbiculatus. Herbaceous species documented from the same site include Ageratina altissima, Ambrosia trifida, Boehmeria cylindrica, Commelina virginica, Elephantopus carolinianus, Geum canadense, Impatiens capensis, Iresine rhizomatosa, Lactuca floridana, Laportea canadensis, Menispermum canadense, Phytolacca americana, Pilea pumila, Polygonum virginianum, Rudbeckia laciniata, Rudbeckia triloba, Ruellia strepens, Sicyos angulatus, Smallanthus uvedalius, Toxicodendron radicans, Verbesina alternifolia, and Verbesina virginica. This community may be better considered a northern extension of bottomland forests found farther south. Future consolidation of types may be warranted.

Classification Comments: This community may be better considered a northern extension of bottomland forests found farther south [see ~Platanus occidentalis - Fraxinus pennsylvanica - Celtis laevigata - (Liquidambar styraciflua) Floodplain Forest (CEGL007913)$$]. Future consolidation of types may be warranted. This type of forest is uncommon in the Ozarks, as most rivers in that region do not form the broad bottomlands with the deep soils needed to support this type of vegetation.
