CEGL004649 Pinus taeda - Acer rubrum - Liquidambar styraciflua / Arundinaria tecta Ruderal Wet Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Loblolly Pine - Red Maple - Sweetgum / Switch Cane Ruderal Wet Forest
Colloquial Name: Great Dismal Swamp Ruderal Peat Dome Pine-Hardwood Wet Forest
Hierarchy Level: Association
Type Concept: This community is extensively distributed in the northern portion of the Great Dismal Swamp, on the margins of large peat domes, where peat feathers out into mineral soil. The type is a young, successional type which has probably replaced both hydrophytic oak forests and nearly treeless canebrakes following extensive cutting, fire suppression, and hydrologic alteration. Hydrology is saturated by permanently high water tables, with occasional shallow surface ponding during extended wet periods. Soils range from loamy sands to silty clay loams, with or without an organic mantle up to 30 cm deep. Pinus taeda, Acer rubrum var. trilobum, and Liquidambar styraciflua dominate the canopy in various combinations and proportions. The sparse subcanopy can include Acer rubrum, Liquidambar styraciflua, Nyssa sylvatica, Fraxinus pennsylvanica, Magnolia virginiana, Quercus laurifolia, Quercus nigra, Quercus michauxii, and Quercus alba. Arundinaria tecta occurs in dense (or sometimes patchy) stands. Other shrubs include Clethra alnifolia, Vaccinium formosum, Vaccinium fuscatum, Smilax rotundifolia, Smilax glauca, Ilex opaca, Ilex glabra, Morella cerifera, Persea palustris, Eubotrys racemosa, and Toxicodendron radicans ssp. radicans. Locally, Lyonia lucida and Asimina triloba may occur, as well. Herbaceous species are sparse to essentially lacking, but can include Woodwardia areolata, Woodwardia virginica, Osmunda cinnamomea, and Osmunda regalis var. spectabilis.

Floristics: Stands of this association are dominated by Pinus taeda, Acer rubrum var. trilobum, and Liquidambar styraciflua in various combinations and proportions. The sparse subcanopy can include Acer rubrum, Liquidambar styraciflua, Nyssa sylvatica, Fraxinus pennsylvanica, Magnolia virginiana, Quercus laurifolia, Quercus nigra, Quercus michauxii, and Quercus alba. Arundinaria tecta (= Arundinaria gigantea ssp. tecta) occurs in dense (or sometimes patchy) stands. Other shrubs include Clethra alnifolia, Vaccinium formosum, Vaccinium fuscatum, Smilax rotundifolia, Smilax glauca, Ilex opaca, Ilex glabra, Morella cerifera (= Myrica cerifera var. cerifera), Persea palustris, Eubotrys racemosa (= Leucothoe racemosa), and Toxicodendron radicans ssp. radicans. Locally, Lyonia lucida and Asimina triloba may occur, as well. Herbaceous species are sparse to essentially lacking but can include Woodwardia areolata, Woodwardia virginica, Osmunda cinnamomea, and Osmunda regalis var. spectabilis. Occurrences of this community at Dismal Swamp State Natural Area in North Carolina have canopies almost completely dominated by Acer rubrum and open subcanopy and dense shrub layer of Arundinaria tecta (LeGrand 1994).
Dynamics: The type is a young, successional type which has probably replaced both hydrophytic oak forests and nearly treeless canebrakes following extensive cutting, fire suppression, and hydrologic alteration.
