CEGL007129 Pinus palustris / Quercus margarettae / Toxicodendron pubescens / Schizachyrium scoparium Woodland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Longleaf Pine / Sand Post Oak / Atlantic Poison-oak / Little Bluestem Woodland

Colloquial Name: Southern Inner Coastal Plain Silty Longleaf Pine / Sand Post Oak Woodland

Hierarchy Level:  Association

Type Concept: This association spans a broad geographic range of subxeric longleaf pine woodlands of the Inner Coastal Plain from central South Carolina to the Alabama border. It occurs on silty sites. Because of its broad spatial distribution, there is some turnover of species in this type depending on geographic position. However, the subcanopy is consistently dominated by Quercus margarettae with slightly lesser amounts of Quercus laevis and Quercus incana, reflecting the subxeric, silty nature of the sites. The high frequency of Toxicodendron pubescens also suggests the silty, subxeric nature of soils this type occurs on, as does the abundance of legumes. Aristida beyrichiana can be a ground layer dominant, but the type extends beyond the range of the species, both in central South Carolina and in western Georgia. The herbaceous layer is species-rich, reflecting the silty nature of the soils of this type. Other characteristic species include Carya tomentosa, Rhus copallinum, Ceanothus americanus, Lespedeza hirta, Mimosa microphylla, Clitoria mariana, Ionactis linariifolius, Pityopsis graminifolia, and Solidago odora.

Diagnostic Characteristics: This subxeric, silty type is distinguished by the dominance of Quercus margarettae in the subcanopy layer, Toxicodendron pubescens in the shrub layer, and a species-rich herbaceous layer dominated primarily by Schizachyrium scoparium.

Classification Comments: Concept and description are based on 14 plots from the Carolina Vegetation Survey. This concept is somewhat similar to, but not equivalent to, ~Pinus palustris / Quercus hemisphaerica / Gaylussacia dumosa / Aristida beyrichiana - Dyschoriste oblongifolia Woodland (CEGL004488)$$, particularly in that it extends beyond the range of Aristida beyrichiana in both the northeast and the west, and in so doing covers variation not previously represented in the USNVC.

Physiognomy and Structure: No Data Available

Floristics: Stands are dominated by an open canopy of Pinus palustris with an understory layer dominated by Quercus margarettae, although Quercus laevis, Quercus incana, Quercus marilandica, and Quercus falcata are also common. Common and indicative shrub species include Gaylussacia dumosa, Vaccinium stamineum, Toxicodendron pubescens, Rhus copallinum, and Hypericum hypericoides. The herbaceous layer is very diverse with many species of legumes and is either dominated by Aristida beyrichiana or Schizachyrium scoparium, depending on whether the site occurs within the range of Aristida beyrichiana. Smilax bona-nox and Smilax glauca are common vines. Other constant plants (in 75% or more of plots attributed to this type) include Dichanthelium aciculare, Dichanthelium ovale, Eupatorium compositifolium, Eupatorium glaucescens, Gymnopogon ambiguus, Hieracium gronovii, Ionactis linariifolius, Pityopsis graminifolia, Rhynchosia reniformis, Sericocarpus tortifolius, Solidago odora var. odora, Stylisma patens, Stylosanthes biflora, Symphyotrichum concolor, Tragia urens, and Vernonia angustifolia. Other characteristic species include Carya tomentosa, Rhus copallinum, Ceanothus americanus, Lespedeza hirta, Mimosa microphylla, Clitoria mariana, Ionactis linariifolius, Pityopsis graminifolia, and Solidago odora.

Dynamics:  No Data Available

Environmental Description:  Stands are found on yellow sand soils of the Inner Coastal Plain, with a relatively high silt fraction, as opposed to more pure white sands. Soil moisture in this type is bordering on mesic.

Geographic Range: This association is broadly distributed from central South Carolina to southwestern Georgia in the Inner Coastal Plain. Occurrences have been documented in Chattahoochee, Jenkins, and Screven counties, Georgia, and in Charleston, Dorchester, Allendale, Sumter, and Colleton counties, South Carolina.
