CEGL004606 Pinus taeda - Liquidambar styraciflua - Nyssa biflora Ruderal Floodplain Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Loblolly Pine - Sweetgum - Swamp Tupelo Ruderal Floodplain Forest

Colloquial Name: Ruderal Loblolly Pine - Sweetgum - Swamp Tupelo Floodplain Forest

Hierarchy Level:  Association

Type Concept: This association includes forests dominated by the nominal species on slightly elevated ridges of floodplains primarily in the Atlantic Coastal Plain and the adjacent East Gulf Coastal Plain. The canopy of this successional forest is typically dominated by some combination of Pinus taeda, Liquidambar styraciflua, and Nyssa biflora. A mixture of other bottomland hardwood species may be present which includes Diospyros virginiana, Quercus nigra, Acer rubrum, Quercus michauxii, Quercus laurifolia, Ulmus alata, Carya cordiformis, Ulmus americana, Quercus pagoda, Celtis laevigata, Quercus phellos, Fagus grandifolia, Carya tomentosa, and others. Asimina triloba may be prominent in the understory with Ilex decidua, Carpinus caroliniana, Crataegus viridis, Crataegus spathulata, Ilex opaca, and other species. These forests develop following disturbance and may persist.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Pederson et al. (1997) report old stands at Congaree Swamp National Monument dominated by Pinus taeda, Liquidambar styraciflua, Carpinus caroliniana, and Ilex opaca. This vegetation is apparently accommodated in the USNVC as a Pinus taeda-containing "phase" of ~Liquidambar styraciflua - Quercus laurifolia - (Pinus taeda) / Arundinaria gigantea / Carex abscondita Floodplain Forest (CEGL007732)$$.

Floristics: The canopy is dominated by some combination of Pinus taeda, Liquidambar styraciflua, and Nyssa biflora. A mixture of other bottomland hardwood species may be present which includes Diospyros virginiana, Quercus nigra, Acer rubrum, Quercus michauxii, Quercus laurifolia, Ulmus alata, Carya cordiformis, Ulmus americana, Quercus pagoda, Celtis laevigata, Quercus phellos, Fagus grandifolia, Carya tomentosa (= Carya alba), and others. Asimina triloba may be prominent in the understory with Ilex decidua, Carpinus caroliniana, Crataegus viridis, Crataegus spathulata, Ilex opaca, Arundinaria gigantea, and other species. Vines such as Vitis rotundifolia, Vitis aestivalis, Smilax spp., Cocculus carolinus, and Berchemia scandens may be important, and the herbaceous layer likely includes Boehmeria cylindrica, Carex spp., and scattered ferns such as Onoclea sensibilis. At Ocmulgee National Monument near Macon, Georgia, invasive exotic Ligustrum sinense can dominate the shrub layer.

Dynamics:  These forests develop following disturbance and may persist.

Environmental Description:  These are forests dominated by the nominal species on slightly elevated ridges of floodplains primarily in the Atlantic Coastal Plain, ranging into the adjacent East Gulf Coastal Plain.

Geographic Range: These forests are primarily found in the Atlantic Coastal Plain and the adjacent East Gulf Coastal Plain of the United States.
