CEGL004086 Pinus palustris / Schizachyrium scoparium - Muhlenbergia expansa - Arnoglossum ovatum Woodland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Longleaf Pine / Little Bluestem - Cutover Muhly - Savanna Indian-plantain Woodland

Colloquial Name: Atlantic Coastal Plain Wet Ultisol Longleaf Pine / Little Bluestem Savanna

Hierarchy Level:  Association

Type Concept: This seasonally saturated longleaf pine - pond pine - loblolly pine woodland association is restricted to wet and moist Ultisols of the wiregrass gap region of South Carolina. The open canopy of this association is dominated by a combination of Pinus palustris, Pinus serotina, and Pinus taeda. The ground layer is dominated by Schizachyrium scoparium, Muhlenbergia expansa, Ctenium aromaticum, Setaria parviflora, and Eryngium yuccifolium. Several species thought to be indicative of shallow lime bedrock (i.e., coquina limestone) occur commonly in this association, including Setaria parviflora, Panicum virgatum, Arnoglossum ovatum, Plantago sparsiflora, and Apocynum cannabinum. However, the stand in Francis Marion National Forest, South Carolina, on which the present description is primarily based, occurs on a Wahee loam, an Ultisol not evidently associated with shallow limestone. The stand is directly adjacent to a hardwood-dominated drainage, however, so there may be some extruding limestone.

Classification Comments: As indicated in the discussion of similar associations, there is much compositional overlap among the various recognized and proposed wet Ultisol savanna and flatwoods communities of the wiregrass gap region. Though subtle environmental differences may be apparent, it is hypothetically plausible that much of the variation, particularly in composition of dominant grasses, may be random and independent of the environment (Glitzenstein and Streng 2004).

Floristics: The open canopy of this association is dominated by a combination of Pinus palustris, Pinus serotina, and Pinus taeda. Dominant ground-layer grasses include Schizachyrium scoparium, Muhlenbergia expansa, Ctenium aromaticum, Andropogon capillipes (wet variant), Andropogon glomeratus, Panicum virgatum, and Setaria parviflora. Other commonly occurring grasses and sedges may include Andropogon gerardii, Rhynchospora elliottii, Rhynchospora rariflora, Scleria muehlenbergii, Panicum verrucosum, Panicum anceps, Paspalum praecox, Fimbristylis puberula, Dichanthelium dichotomum, Dichanthelium dichotomum var. tenue (= Dichanthelium tenue), Dichanthelium strigosum var. leucoblepharis, Tridens ambiguus, and Rhynchospora debilis. In addition, Ilex glabra, Quercus pumila, and Morella cerifera (= Myrica cerifera) may be important in the shrub layer depending on fire history. Eryngium yuccifolium and Arnoglossum ovatum are dominant forbs. Other common to abundant forbs include Eupatorium leucolepis, Eupatorium mohrii, Chaptalia tomentosa, Coreopsis linifolia, Solidago stricta, Liatris spicata, Hyptis alata, Symphyotrichum walteri (= Aster walteri), Pityopsis graminifolia, Helianthus angustifolius, Pluchea rosea, Symphyotrichum dumosum (= Aster dumosus), Centella erecta, Marshallia graminifolia, Erigeron vernus, Bigelowia nudata, Rhexia alifanus, Agalinis purpurea, the globally endangered Plantago sparsiflora, and many others (Glitzenstein and Streng 2004).

Dynamics:  The maintenance of this vegetation type depends on frequent low-intensity fires that limit competition from hardwood trees and shrubs and help to maintain the high diversity of herbaceous vegetation (Glitzenstein et al. 2003).

Environmental Description:  This association occurs on level, poorly drained soils with loam surface soil and a clayey subsoil (e.g., Wahee Loam). Limestone bedrock may underlie the soil profile at a relatively shallow depth. More soil data are needed; this should have higher calcium.

Geographic Range: This type is known from the Atlantic Coastal Plain of South Carolina, particularly the wiregrass gap region.
