Quercus virginiana - Quercus pagoda - Liquidambar styraciflua / Sabal minor - Ilex vomitoria Swamp Forest
Translated Name: Live Oak - Cherrybark Oak - Sweetgum / Dwarf Palmetto - Yaupon Swamp Forest
Common Name: Southern Atlantic Coastal Plain Wet Flat Forest
Unique Identifier: CEGL007851
Classification Approach: International Vegetation Classification (IVC)
Summary: This community occurs in South Carolina on low moist to wet flats, near the conceptual line between upland and saturated hydrologies. These sites never receive overland flooding from rivers or streams. Quercus virginiana and Quercus pagoda dominate the canopy; other canopy and subcanopy species may include Liquidambar styraciflua, Quercus nigra, Quercus laurifolia, Quercus phellos, Magnolia grandiflora, Ulmus americana, Ulmus alata, and Celtis laevigata var. laevigata. Sabal minor forms a dense shrub layer, often intermixed with substantial Ilex vomitoria and Morella cerifera (= Myrica cerifera var. cerifera). Woody vines are common and include Berchemia scandens, Toxicodendron radicans ssp. radicans, Campsis radicans, and Bignonia capreolata. Herbs are few but may include Chasmanthium laxum, Chasmanthium sessiliflorum, and Juncus coriaceus. Tillandsia usneoides and Pleopeltis polypodioides ssp. michauxiana are common epiphytes. Some areas supporting this community were in row-crop agriculture in the early eighteenth century, and the origin and naturalness of this community are somewhat uncertain.
