South Atlantic Coastal Plain Longleaf Flatwoods


Element Identifiers

NVCS association: Pinus palustris / Serenoa repens - Vaccinium myrsinites / Aristida beyrichiana - Sporobolus curtissii Woodland

Database Code: CEGL004486

Formation: Rounded-crowned temperate or subpolar needle-leaved evergreen woodland

Alliance: PINUS PALUSTRIS WOODLAND ALLIANCE (II.A.4.N.a.22)

Element Concept

Summary: This Pinus palustris flatwoods community is found in the South Atlantic Coastal Plain of northeastern Florida and southern Georgia. It is typified by a very open canopy of Pinus palustris which rarely exceeds 25% total coverage. Some stands have relatively minor amounts of Pinus elliottii present as well. Sporobolus curtissii is diagnostic of this type, at least relative to other Pinus palustris flatwoods in northern Florida. Aristida beyrichiana is also common. . The shrub layer is well-developed and often dense, usually dominated by some combination of Serenoa repens, Vaccinium myrsinites, Gaylussacia tomentosa (= Gaylussacia frondosa var. tomentosa), Gaylussacia dumosa (= var. dumosa), Ilex glabra, Lyonia lucida, Quercus minima, and lesser amounts of Quercus pumila. In some sites, the herb layer is poorly developed and not very diverse; in other areas Sporobolus curtissii and Aristida beyrichiana are abundant and other herbs are diverse.

Environment: This longleaf pine woodland community occurs on sandy, mesic to moderately dry soils with low pH.

Vegetation: It is typified by a very open canopy of Pinus palustris which rarely exceeds 25% total coverage. Some stands have relatively minor amounts of Pinus elliottii present as well. Aristida beyrichiana is common in this type as well as other flatwoods in the East Gulf Coastal Plain. Sporobolus curtissii is diagnostic of this type, at least relative to other Pinus palustris flatwoods in northern Florida where it was not recorded at all (NatureServe unpubl. data). Andropogon virginicus var. virginicus and Aristida spiciformis show similar patterns of distribution (NatureServe unpubl. data). The shrub layer is well-developed and often dense, usually dominated by several of Serenoa repens, Vaccinium myrsinites, Gaylussacia tomentosa (= Gaylussacia frondosa var. tomentosa), Gaylussacia dumosa (= var. dumosa), Gaylussacia nana, Ilex glabra, and Lyonia fruticosa. In some sites, the herb layer is poorly developed and not very diverse; in other areas Sporobolus curtissii and Aristida beyrichiana are abundant and other herbs are diverse.

Conservation Ranking & Rare Species

GRank: G2G3 (97-05-03): This longleaf pine woodland association is found in a restricted range and specific set of habitat conditions. It is restricted to sandy, mesic to moderately dry soils with low pH. The open canopy is dominated by longleaf pine and may also contain some slash pine. It is part of the endangered Longleaf Pine Ecosystem, which once dominated the Coastal Plain landscape of the southeastern United States, and depends on frequent, low-intensity, growing-season fires to control understory vegetation and for the reproduction of Pinus palustris. Pinus palustris-dominated woodlands are susceptible to the effects of fire suppression, over-grazing, or conversion to commercial forest plantations or agriculture. Remaining examples are highly threatened by development, conversion, and alteration of fire regimes. Most of those occurrences which have not been destroyed are severely degraded, except for examples on military lands, where incidental burning has maintained more-or-less natural fire regimes.

Successional Loblolly Pine - Oak Forest


Element Identifiers

NVCS association: Pinus taeda - Quercus (falcata, hemisphaerica, nigra) - Liquidambar styraciflua / Rhus copallinum - Vaccinium stamineum Forest

Database Code: CEGL008450

Formation: Mixed needle-leaved evergreen - cold-deciduous forest

Alliance: PINUS TAEDA - QUERCUS (ALBA, FALCATA, STELLATA) FOREST ALLIANCE (I.C.3.N.a.24)

Element Concept

Summary: This successional forest of the Upper East Gulf Coastal Plain is dominated by a mixture of Pinus taeda with hardwoods, including Quercus spp. and Liquidambar styraciflua. The oaks present may include Quercus falcata, Quercus hemisphaerica, and Quercus nigra. These forests develop on former mesic to dry-mesic Pinus palustris sites, following removal of Pinus palustris and disturbance. There may be some variation in canopy composition with soil texture. Quercus hemisphaerica may be more prevalent on sandy soils, Quercus nigra on finer-textured ones. Common shrubs include Rhus copallinum and Vaccinium stamineum.

Environment: This forest is described from the Upper East Gulf Coastal Plain of Fort Benning, Georgia. It occurs on rolling uplands on sandy loam soils at various aspects. These forests develop on former mesic to dry-mesic Pinus palustris sites, following removal of Pinus palustris and disturbance.

Vegetation: The canopy is dominated by a mixture of Pinus taeda with hardwoods, including Quercus spp. and Liquidambar styraciflua. The oaks present may include Quercus falcata, Quercus hemisphaerica, and Quercus nigra. Quercus hemisphaerica may be more prevalent on sandy soils, Quercus nigra on finer-textured ones. Common shrubs include Rhus copallinum and Vaccinium stamineum. On the Apalachicola National Forest, a related somewhat diverse stand on dissected slopes near a creek contains Pinus taeda, Nyssa biflora, Quercus hemisphaerica, Quercus nigra, Liquidambar styraciflua, Magnolia virginiana, Magnolia grandiflora, and Acer rubrum. Shrubs are moderately diverse and include Clethra alnifolia, Cliftonia monophylla, Cyrilla racemiflora, Ilex coriacea, Ilex opaca, Itea virginica, Leucothoe axillaris, Lyonia lucida, Osmanthus americanus, Symplocos tinctoria, and Vaccinium stamineum. The classification status of this stand is somewhat unclear, but it is placed here pending further investigation. It may be in fact a fully natural, not a "modified" type.

Similar Associations:

  • Pinus taeda / Liquidambar styraciflua - Acer rubrum var. rubrum / Vaccinium stamineum Forest (CEGL006011)

  • Pinus taeda Planted Forest (CEGL007179)--applies to young, dense, monospecific, stands with plantation structure.

Synonymy: No information

Comments: There may be substantial hardwoods (Quercus spp., Liquidambar styraciflua) in the canopy and subcanopy, but this association is primarily composed of Pinus taeda.
