A3700 Fraxinus pennsylvanica - Platanus occidentalis - Acer saccharinum Ozark-Ouachita Floodplain Forest Alliance
Type Concept Sentence: These forests of floodplains, bottomlands, and terraces are dominated by some combination of Fraxinus pennsylvanica, Ulmus americana, and Acer saccharinum, and are primarily found in the Ozarks, Ouachita Mountains, Interior Low Plateau, and Mississippi River Alluvial Plain.
Common (Translated Scientific) Name: Green Ash - American Sycamore - Silver Maple Ozark-Ouachita Floodplain Forest Alliance
Colloquial Name: Ozark-Ouachita Green Ash - Sycamore - Silver Maple Floodplain Forest
Hierarchy Level: Alliance
Type Concept: These forests are dominated by some combination of Acer saccharinum, Fraxinus pennsylvanica, and Ulmus americana. Other species found in examples of this alliance include Acer negundo, Betula nigra, Carya illinoinensis, Celtis laevigata, Gleditsia triacanthos, Liquidambar styraciflua, Platanus occidentalis, and Quercus texana. Stands of Arundinaria gigantea are often encountered in the lower strata of these forests. Examples are found in floodplains, bottomlands, and terraces of the Ozarks, Ouachita Mountains, Interior Low Plateau, and Mississippi River Alluvial Plain.
Diagnostic Characteristics: These are diverse floodplain and bottomland forests of the Ozarks, Ouachita Mountains, Interior Low Plateau, Mississippi River Alluvial Plain, and the adjacent Upper West Gulf Coastal Plain dominated by some combination of Acer saccharinum, Fraxinus pennsylvanica with some Ulmus americana. This combination of floristics and biogeography should be diagnostic. This is in contrast to other bottomland forests of the same region with heavier dominance by Ulmus americana, Ulmus crassifolia, and Celtis laevigata.

Environmental Description: Examples are found in floodplains, bottomlands, and terraces.
Geographic Range: This alliance is primarily found in the Ozarks, Ouachita Mountains, Interior Low Plateau, and Mississippi River Alluvial Plain, as well as the adjacent Upper West Gulf Coastal Plain, from Missouri, Illinois, Indiana and Arkansas south to Louisiana and east to Tennessee. One wide-ranging association is at least peripherally attributed to the Central Tallgrass Prairie and East Gulf Coastal Plain, and one to the Ridge and Valley.
