CEGL003586 Pinus palustris / Quercus laevis / Aristida stricta - Baptisia cinerea Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Longleaf Pine / Turkey Oak / Pineland Three-awn - Gray-hairy Wild Indigo Woodland
Colloquial Name: Fall-line Sandhills Dry Longleaf Pine Woodland
Hierarchy Level: Association
Type Concept: This association covers the widespread longleaf pine communities of dry sands and occurs mostly in the Fall-line Sandhills, where plants characteristic of the coastal fringe are absent. Stands are dominated by Pinus palustris with a low-diversity scrub oak layer strongly dominated by Quercus laevis and a well-developed herbaceous layer dominated by Aristida stricta. Gaylussacia dumosa is a common, abundant shrub component.

Classification Comments: Description has been changed based on 32 plots from the Carolina Vegetation Survey (http://vegbank.org\cite\VB.ds.199636.CEGL003586). Subassociation A is based on 22 fire-maintained plots (http://vegbank.org\cite\VB.ds.199677.CEGL003586A), while Subassociation B is based on 10 slightly fire-suppressed plots (http://vegbank.org\cite\VB.ds.199678.CEGL003586b). The geographic scope has been slightly narrowed. It was originally defined as a broad type that includes infertile sands in the Fall-line Sandhills region and the inner Coastal Plain. The new definition is narrower and is essentially limited to the Fall-line Sandhills. The name has been modified to put less emphasis on Gaylussacia dumosa and include Baptisia cinerea as indicative in the herbaceous layer.

Floristics: Stands are dominated by Pinus palustris with a subcanopy/shrub layer dominated almost exclusively by Quercus laevis. Quercus incana is often present, but at much lower abundance than Quercus laevis. Characteristic low shrubs include Gaylussacia dumosa (= var. dumosa) and Hypericum hypericoides. Aristida stricta dominates the herbaceous layer and often has high abundance. Other characteristic herbaceous plants include Baptisia cinerea, Carphephorus bellidifolius, Cirsium repandum, Cnidoscolus urens var. stimulosus (= Cnidoscolus stimulosus), Diospyros virginiana, Euphorbia ipecacuanhae, Pityopsis graminifolia, Physalis virginiana, and Rhynchospora grayi. This association can be distinguished from other community types by the presence of a scrub oak layer strongly dominated by Quercus laevis along with an herbaceous layer dominated by Aristida stricta.
Two subassociations are recognized within this type: Subassociation A, which is fire-maintained, and Subassociation B, which is relatively fire-suppressed. As is typical with fire suppression, the abundance and diversity of woody components in considerably higher in Subassociation B, while the abundance of grasses and forbs (particularly Aristida stricta) is considerably less.

Environmental Description: This association covers the widespread longleaf pine communities of dry sands, found primarily in the Fall-line Sandhills, on dry sandy soils, often with some silt, including Arenic Paledults, Arenic Kanhapludults, Typic Kanhapludults, Typic Udipsamments, Typic Quartzipsamments, Aquic Quartzipsamments, Entic Grossarenic Alorthods, and Lamellic Quartzipsamments.
Geographic Range: This association is restricted to the Sandhills and Coastal Plain regions of the Mid-Atlantic Coastal Plain of North and South Carolina. It (or some related vegetation) may occur in the immediately adjacent Piedmont. It is currently known from Bladen, Cumberland, Hoke, Moore, Richmond, and Scotland counties, North Carolina, and Chesterfield County, South Carolina.
