CEGL007730 Platanus occidentalis - Celtis laevigata - Fraxinus pennsylvanica / Ilex decidua / Carex retroflexa Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Sycamore - Sugarberry - Green Ash / Possum-haw / Reflexed Sedge Floodplain Forest
Colloquial Name: American Sycamore - Sugarberry - Green Ash Floodplain Forest
Hierarchy Level: Association
Type Concept: This forest association occurs on terraces of associated rivers and large creeks in the Mid-Atlantic Coastal Plain, lower Piedmont, and possibly in adjacent regions. These are relatively more well-drained than the adjacent flats. The mostly closed canopy of this community is dominated by Platanus occidentalis, Celtis laevigata, and Fraxinus pennsylvanica. These species, along with Acer negundo, are important in the well-developed subcanopy also. Other tree species are possible in these strata; these include Crataegus viridis, Juglans nigra, Acer saccharinum, Morus rubra, Ilex decidua, Ulmus americana, Planera aquatica, Quercus laurifolia, Quercus nigra, Liquidambar styraciflua, Populus deltoides, Carya aquatica, and others. The shrub layer generally is sparse and is dominated by Lindera benzoin, Ilex decidua, Asimina triloba, and likely other species as well. Some examples of this community also have patches of Arundinaria gigantea in spots. The herbaceous layer is typically sparse to moderate and constant species are Boehmeria cylindrica, Carex grayi, Carex retroflexa, and Viola spp. Other typical species include Botrychium dissectum, Carex frankii, Carex lupulina, Chasmanthium latifolium, Onoclea sensibilis, Pilea pumila, Polygonum hydropiperoides, Polygonum virginianum, and others. The vine stratum is moderate and many species are possible. Among these are Bignonia capreolata, Parthenocissus quinquefolia, Smilax tamnoides, Vitis rotundifolia, Nekemias arborea, Berchemia scandens, Gelsemium sempervirens, and Toxicodendron radicans. Exotic species such as Ligustrum sinense, Lonicera japonica, and Microstegium vimineum may invade stands of this association, and increase following disturbance. This forest type is documented in the Mid-Atlantic Coastal Plain (and lower Piedmont) but is possible in adjacent regions; global distribution needs assessment.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association was described based on 1998 data from the Congaree National Park. The exotics Ligustrum sinense and Microstegium vimineum may be dominant in occurrences of this community. Related vegetation in Virginia is treated as ~Fraxinus pennsylvanica - Platanus occidentalis - Celtis laevigata / Chasmanthium latifolium Piedmont Floodplain Forest (CEGL007013)$$.

Floristics: The mostly closed canopy of this community is dominated by Platanus occidentalis, Celtis laevigata, and Fraxinus pennsylvanica. These species, along with Acer negundo, are important in the well-developed subcanopy also. Other tree species are possible in these strata and include Crataegus viridis, Juglans nigra, Acer saccharinum, Morus rubra, Ilex decidua, Ulmus americana, Planera aquatica, Quercus laurifolia, Liquidambar styraciflua, Carya aquatica, and others. The shrub layer generally is sparse and is dominated by Lindera benzoin, Ilex decidua, Asimina triloba, and likely other species as well. Acer floridanum (= Acer barbatum) may be an important shrub-layer component at the southern end of this community''s range. Some examples of this community also have patches of Arundinaria gigantea in spots. The herbaceous layer is typically sparse; constant species are Boehmeria cylindrica, Carex grayi, Carex retroflexa, and Viola spp. Other typical species include Botrychium dissectum, Carex lupulina, Chasmanthium latifolium, Onoclea sensibilis, Pilea pumila, Polygonum hydropiperoides, Polygonum virginianum, and others.

Environmental Description: This forest occurs on terraces of associated rivers and on well-drained bottoms of creeks in the Mid-Atlantic Coastal Plain, lower Piedmont, and possibly in adjacent regions. These terraces are relatively more well-drained than the adjacent flats.
Geographic Range: This forest type is documented in the Mid-Atlantic Coastal Plain and lower Piedmont, but is possible in adjacent regions; global distribution needs assessment.
