CEGL007806 Fraxinus pennsylvanica - Ulmus americana / Carpinus caroliniana / Boehmeria cylindrica Floodplain Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Green Ash - American Elm / American Hornbeam / Small-spike False Nettle Floodplain Forest

Colloquial Name: Southeastern Coastal Plain Green Ash - Elm Bottomland Forest

Hierarchy Level:  Association

Type Concept: This green ash - elm forest occurs in floodplains of major rivers (and parts of their larger tributaries) in the Atlantic and adjacent East Gulf coastal plains, as well as portions of the Piedmont. The typical habitats are generally alluvial or brownwater rivers, on low ridges, flats, and sloughs of first bottoms; terrace flats and sloughs; and on well-drained, relatively fertile levees and backsides of levees. Soils are clay or silt loams with alluvial deposition. This community typically has an uneven-aged canopy dominated by Fraxinus pennsylvanica, Ulmus americana, and Celtis laevigata. Other typical canopy species include Acer negundo, Liquidambar styraciflua, Acer rubrum, Acer saccharinum, Morus rubra, Platanus occidentalis, Ulmus alata, and others. The understory stratum includes Carpinus caroliniana, Cornus foemina, Ilex decidua, Morus rubra, and Crataegus spp. The herbaceous and vine strata are sparse to abundant. Composition may vary somewhat with flooding regime and geographic location. Common species are Boehmeria cylindrica, Carex lupulina, Carex retroflexa, Carex grayi, Carex abscondita, Pilea pumila, Carex louisianica, Arisaema dracontium, Saururus cernuus, Matelea carolinensis, Leersia lenticularis, Chasmanthium latifolium, Justicia ovata, Carex intumescens, and others. Common vine species in this community are Vitis rotundifolia, Campsis radicans, Parthenocissus quinquefolia, Toxicodendron radicans, Bignonia capreolata, Cocculus carolinus, and others.

Classification Comments: This association was originally described based on data from the Roanoke River of North Carolina (Rice and Peet 1997). The global distribution of this community needs to be further evaluated, particularly in relation to data from Congaree Swamp National Monument. The name used for this type in Rice and Peet (1997) is the name of the national type ~Fraxinus pennsylvanica - Ulmus americana - Celtis laevigata / Ilex decidua Floodplain Forest (CEGL002427)$$ from which this type was split (this was after the Rice and Peet report was issued). Compare Fort Benning data to Roanoke River data; some stands at Fort Benning contain Betula nigra, this probably successional.

Environmental Description:  This community occurs in floodplains of major rivers (and parts of their larger tributaries) in the Atlantic and adjacent East Gulf coastal plains, as well as portions of the Piedmont, generally alluvial or brownwater rivers, on low ridges, flats, and sloughs of first bottoms; terrace flats and sloughs; and on well-drained, relatively fertile levees and backsides of levees. Soils are clay or silt loams with alluvial deposition. Some stands assigned here from Fort Benning, Georgia, are from a creek tributary of the Chattahoochee River.

Geographic Range: This forest is found throughout the Atlantic and East Gulf coastal plains from North Carolina south to Georgia and possibly to Florida, as well as in the Piedmont of Alabama (Horseshoe Bend National Military Park).
