CEGL007728 Fraxinus pennsylvanica / Leersia lenticularis - Carex lupulina Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Green Ash / Catchfly Grass - Hop Sedge Floodplain Forest
Colloquial Name: Atlantic Coastal Plain Green Ash Slough Forest
Hierarchy Level: Association
Type Concept: This forest occurs on somewhat poorly drained to poorly drained silty clay loam soils in temporarily flooded sloughs in the Atlantic Coastal Plain. The mostly closed to closed canopy of this community is dominated by Fraxinus pennsylvanica. Other typical canopy species include Ulmus americana, Acer negundo, and Carya aquatica. The well-developed subcanopy may contain the same species as the canopy; additional species in this stratum include Planera aquatica, Celtis laevigata, Ilex decidua, Ulmus alata, Crataegus phaenopyrum, and Diospyros virginiana. The single occurrence on which this description is based had no shrub cover. The herbaceous layer is typically of moderate density and dominated by Leersia lenticularis, Boehmeria cylindrica, and Carex lupulina with Saururus cernuus and Polygonum setaceum. The vine coverage is moderate, and species present include Smilax tamnoides, Vitis rotundifolia, Campsis radicans, Toxicodendron radicans, Menispermum canadense, and Nekemias arborea. This forest currently is known only from the Mid-Atlantic Coastal Plain of South Carolina.
