CEGL007737 Quercus michauxii / Carpinus caroliniana - Ilex opaca / Eubotrys racemosa Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Swamp Chestnut Oak / American Hornbeam - American Holly / Swamp Doghobble Floodplain Forest
Colloquial Name: Atlantic Coastal Plain Brownwater Floodplain Oak Seepage Forest
Hierarchy Level: Association
Type Concept: This forest community occurs on the edges of brownwater floodplains in the Atlantic Coastal Plain, in situations that are very rarely flooded by alluvial waters, but which receive regular seepage from adjacent upland slopes. The hydrology is constantly saturated, and soils are silty clay with organic matter present. This association has a closed canopy and moderate to sparse subcanopy, shrub, herbaceous, and vine/liana strata. The canopy is dominated by Quercus michauxii. Pinus taeda and Liquidambar styraciflua are typical in the canopy. The subcanopy is dominated by Carpinus caroliniana. Other species that may occur in the canopy or subcanopy include Nyssa sylvatica, Magnolia virginiana, Persea palustris, Quercus pagoda, Acer rubrum, Quercus laurifolia, Quercus nigra, Ulmus alata, Liriodendron tulipifera, Carya tomentosa, Cornus foemina, Ilex decidua, Ilex opaca, Quercus phellos, Carya cordiformis, and others. Eubotrys racemosa is the dominant and characteristic shrub species; other shrubs present can include Ilex verticillata, Callicarpa americana, Viburnum dentatum, Rhododendron canescens, and others. The herbaceous layer is sparse and is weakly dominated by Chasmanthium sessiliflorum. Other species that are typical include Carex bromoides, Osmunda cinnamomea, Pluchea camphorata, Carex scoparia, and Mitchella repens. This forest type is documented in the Mid-Atlantic Coastal Plain, 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 exotic Lonicera japonica may be present. Few stands of this vegetation type have been studied, and rangewide information is limited. The most closely related vegetation in Virginia is treated as ~Quercus laurifolia - Quercus michauxii - Liquidambar styraciflua / Carpinus caroliniana Floodplain Forest (CEGL004678)$$.

Eubotrys racemosa (= Leucothoe racemosa) is the dominant and characteristic shrub species; other shrubs present can include Ilex verticillata, Callicarpa americana, Viburnum dentatum, Rhododendron canescens, and others. The herbaceous layer is sparse and is weakly dominated by Chasmanthium sessiliflorum.
