Pinus taeda / Schizachyrium scoparium Ruderal Woodland
Translated Name: Loblolly Pine / Little Bluestem Ruderal Woodland
Common Name: Ruderal Loblolly Pine / Little Bluestem Woodland
Unique Identifier: CEGL003620
Classification Approach: International Vegetation Classification (IVC)
Summary: This association comprises fire-maintained woodlands of the Southeastern Coastal Plain and adjacent Piedmont, with an open to scattered canopy of Pinus taeda and herb layer dominated by Schizachyrium scoparium. The structure and composition of this community are maintained by fires set by military training; this presumably is not a naturally occurring community. It is only known from outside of the natural range of Pinus palustris.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: This association is apparently restricted to Fort A.P. Hill, Caroline County (northern Coastal Plain), and Fort Pickett, Dinwiddie and Nottoway counties (southern Piedmont), Virginia. Structurally similar vegetation occurs under similar management conditions at Fort Benning, Georgia, but this is within the range of longleaf pine and is not placed here. These stands contain a variable mixture of Pinus taeda and Pinus echinata.

Vegetation

Vegetation Summary: These are woodlands with semi-closed to very open canopies composed almost exclusively of Pinus taeda. Understory growth is typically sparse to negligible, but low colonies of Rhus copallinum are frequent. The herb layer is dominated by dense sods of Schizachyrium scoparium var. scoparium. Danthonia spicata, Andropogon ternarius, Andropogon gyrans, Eragrostis spectabilis, and Gymnopogon brevifolius are additional grasses with significant cover in two sampled plots (Fleming 2002b). The most common forbs are Eupatorium hyssopifolium var. hyssopifolium, Solidago nemoralis, Lespedeza stuevei, Solidago pinetorum, Symphyotrichum concolor (= Aster concolor), and Pityopsis aspera var. adenolepis (= Pityopsis adenolepis). Many other forbs occur at very low cover.


Environmental Setting

Wetland Indicator: N
Environmental Summary: This fire-maintained woodland of the Southeastern Coastal Plain and adjacent Piedmont is presumably not a naturally occurring community.


Dynamic Processes

Dynamics: This could have been a natural type in an area of infrequent but intense fire, where the older trees could have survived (G. Fleming pers. comm.).
