CEGL004321 Quercus alba - Carya tomentosa / Oxydendrum arboreum / Gaylussacia frondosa Coastal Plain Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: White Oak - Mockernut Hickory / Sourwood / Blue Huckleberry Coastal Plain Forest

Colloquial Name: Atlantic Coastal Plain Dry-Mesic Oak - Hickory Forest

Hierarchy Level:  Association

Type Concept: This association is a dry-mesic oak-hickory forest of Coastal Plain bluffs, dissected slopes, and isolated ridges. The canopy has Quercus alba generally most abundant. Carya tomentosa, Quercus velutina, Quercus rubra, Quercus nigra, Liquidambar styraciflua, Liriodendron tulipifera, and Pinus taeda are frequent. The understory is dominated by varying combinations of Oxydendrum arboreum, Cornus florida, Ilex opaca, and Nyssa sylvatica, sometimes with Persea palustris or Magnolia virginiana, along with the canopy species. Frequent shrub species are Gaylussacia frondosa, Symplocos tinctoria, Vaccinium stamineum, Vaccinium tenellum, Hamamelis virginiana, and Styrax americanus. Other species include Morella cerifera, Callicarpa americana, and Vaccinium arboreum. Wetland species such as Ilex glabra or Clethra alnifolia are often present in small numbers. The herb layer is generally sparse, with Chasmanthium laxum, Mitchella repens, and Hexastylis arifolia the most frequent species.

Classification Comments: This association is closely related to ~Quercus alba - Quercus rubra - Carya tomentosa / Vaccinium stamineum / Desmodium nudiflorum Piedmont Forest (CEGL008475)$$. It is distinguished by floristic differences that correspond to the difference between Piedmont and Coastal Plain. These differences are most marked in the lower strata, where a suite of species, individually of low constancy but collectively of high constancy, distinguish the two. Species characteristic of this association but not of the Piedmont association include Gaylussacia frondosa, Symplocos tinctoria, Persea palustris, Magnolia virginiana, Clethra alnifolia, Ilex glabra, Vaccinium elliottii, Arundinaria tecta, Morella cerifera, Callicarpa americana, Woodwardia areolata, Chasmanthium laxum, and Mitchella repens. Species typical of the Piedmont but rare in this association include Vaccinium pallidum, Viburnum rafinesqueanum, Viburnum prunifolium, Viburnum acerifolium, Corylus cornuta, Prunus serotina, Quercus coccinea, Quercus montana, Carya carolinae-septentrionalis, Chionanthus virginicus, and Hieracium venosum.

Physiognomy and Structure: No Data Available

Floristics: The canopy is a mix of trees, with Quercus alba generally most abundant. Carya tomentosa (= Carya alba), Quercus velutina, Quercus rubra, Quercus nigra, Liquidambar styraciflua, Liriodendron tulipifera, and Pinus taeda are frequent. The understory is generally well-developed. It is dominated by varying combinations of Oxydendrum arboreum, Cornus florida, Ilex opaca, and Nyssa sylvatica, sometimes with Persea palustris or Magnolia virginiana, along with the canopy species. The shrub layer ranges from sparse to moderately dense and is variable in composition. Frequent species are Gaylussacia frondosa, Symplocos tinctoria, Vaccinium stamineum, Vaccinium tenellum, Hamamelis virginiana, and Styrax americanus. Other species include Morella cerifera, Callicarpa americana, and Vaccinium arboreum. Wetland species such as Ilex glabra or Clethra alnifolia are often present in small numbers. The herb layer is generally sparse. Chasmanthium laxum, Mitchella repens, and Hexastylis arifolia are the most frequent. Wetland herbs such as Osmunda regalis, Osmunda cinnamomea, or Woodwardia areolata are often present in small numbers.

Dynamics:  This community naturally exists predominantly as uneven-aged, old-growth forest. Stands are subject to small to moderate-sized patch disturbances by windthrow in hurricanes and possibly by fire. They occur in sites that are partially sheltered from fire, but some fires likely penetrate at low intensity.

Environmental Description:  This association occurs on dry-mesic soils on Coastal Plain bluffs, dissected slopes, and occasional isolated ridges in wetlands, generally on upper to midslopes.

Geographic Range: This association occurs on the Atlantic Coastal Plain, from northeastern North Carolina probably to Georgia. It is not known to occur in Virginia.
