CEGL007329 Liquidambar styraciflua - Liriodendron tulipifera / Onoclea sensibilis Floodplain Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Sweetgum - Tuliptree / Sensitive Fern Floodplain Forest

Colloquial Name: Sweetgum - Tuliptree Brownwater Floodplain Forest

Hierarchy Level:  Association

Type Concept: This floodplain forest is found along brownwater rivers in the Atlantic Coastal Plain and adjacent areas of the Piedmont. In addition to Liquidambar styraciflua and Liriodendron tulipifera, the canopy may contain Nyssa biflora (which is a characteristic species of this type in the Coastal Plain) and Acer rubrum. Some stands may contain Betula nigra. The subcanopy is well-developed and contains canopy species along with Carpinus caroliniana, Ilex opaca var. opaca, Persea palustris, Acer floridanum, Cornus florida, Diospyros virginiana, Frangula caroliniana, Quercus phellos, Quercus nigra, and Viburnum nudum var. nudum. Some examples may contain Pinus taeda. Shrubs and vines may include Arundinaria gigantea, Decumaria barbara, Itea virginica, Leucothoe axillaris, Smilax laurifolia, Toxicodendron radicans, Campsis radicans, Parthenocissus quinquefolia, and Vitis rotundifolia. Herbs may include Boehmeria cylindrica, Mitchella repens, Carex spp., Polystichum acrostichoides, Onoclea sensibilis and Woodwardia areolata. In the Piedmont, stands of this association may consist of linear zones along small streams.

Classification Comments: Originally described from wet floodplains of the Savannah River Site, inner Coastal Plain of South Carolina after Jones et al. (1981b) (Yellow poplar-swamp gum-dog hobble community; 10 stands sampled). This association concept needs to be reviewed and compared to similar vegetation of the Coastal Plain and adjacent ecoregions. This association is possible in the Piedmont portions of the Sumter National Forest, but is not documented from there.

Physiognomy and Structure: No Data Available

Floristics: In addition to Liquidambar styraciflua and Liriodendron tulipifera, the canopy may contain Nyssa biflora (which is a characteristic species of this type in the Coastal Plain (Jones et al. 1981b)) and Acer rubrum. An atypical example on the Ocmulgee River at the fall-line of Georgia (Ocmulgee National Monument) has a canopy codominated by Populus deltoides. The subcanopy is well-developed and contains canopy species along with Carpinus caroliniana, Ilex opaca var. opaca, Persea palustris, Acer floridanum (= Acer barbatum), Cornus florida, Diospyros virginiana, Frangula caroliniana, Quercus phellos, Quercus nigra, and Viburnum nudum var. nudum. Some examples may contain Pinus taeda or Ulmus rubra. Shrubs and vines may include Arundinaria gigantea, Berchemia scandens, Crataegus viridis, Decumaria barbara, Ilex ambigua, Itea virginica, Leucothoe axillaris, Sabal minor, Smilax laurifolia, Toxicodendron radicans, Campsis radicans, Parthenocissus quinquefolia, and Vitis rotundifolia. Herbs may include Boehmeria cylindrica, Mitchella repens, Carex spp., Polystichum acrostichoides, Onoclea sensibilis, and Woodwardia areolata (Jones et al. 1981b).

Dynamics:  No Data Available

Environmental Description:  This community is found on highly productive floodplains and upper stream drainages (Jones et al. 1981b). These are associated with brownwater rivers in the South Atlantic Coastal Plain and possibly adjacent ecoregions. In the Piedmont, stands of this association may consist of linear zones along small streams. Some examples are mature forests which developed on formerly cultivated lands.

Geographic Range: This forest is found in the Atlantic Coastal Plain and adjacent areas of the Piedmont.
