East Gulf Coastal Plain Rich Beech - White Oak Forest


Element Identifiers

NVCS association: Fagus grandifolia - Quercus alba - Liquidambar styraciflua / Magnolia grandiflora / Smilax pumila - Hexastylis arifolia Forest

Database Code: CEGL007210

Formation: Lowland or submontane cold-deciduous forest

Alliance: FAGUS GRANDIFOLIA - QUERCUS ALBA FOREST ALLIANCE (I.B.2.N.a.16)

Element Concept

Summary: Mesic mixed hardwood forests of the East Gulf Coastal Plain and perhaps other provinces such as the Upper East Gulf Coastal Plain. Examples of this association contain a canopy dominated by Fagus grandifolia and Quercus alba, with Nyssa sylvatica, Liquidambar styraciflua, and Quercus hemisphaerica (more prevalent on upper slopes). The more-or-less open subcanopy contains Magnolia grandiflora, Magnolia macrophylla, Ostrya virginiana, Liriodendron tulipifera, Acer rubrum, and Cornus florida. Shrubs and woody vines are relatively sparse; shrubs include Arundinaria gigantea, Hamamelis virginiana, Vaccinium elliottii, Ilex decidua, Symplocos tinctoria, Asimina parviflora, and Hypericum hypericoides. Woody vines include Vitis rotundifolia, Gelsemium sempervirens, and Toxicodendron radicans. The herbaceous stratum includes Smilax pumila, Polystichum acrostichoides, Mitchella repens, Arisaema triphyllum, Aristolochia serpentaria, Hexastylis arifolia var. callifolia?, Euphorbia corollata, Scutellaria elliptica, Dichanthelium boscii, Chasmanthium sessiliflorum, Carex spp., Dioscorea villosa, and the epiphyte Pleopeltis polypodioides (= Polypodium polypodioides).

Environment: See Summary

Vegetation: Some stands in the Talladega National Forest, Oakmulgee Ranger District, are clearly related to this type, but do not contain any Magnolia grandiflora and have dense shrub layers composed of Illicium floridanum. They are placed here tentatively, but may be worthy of separate recognition.

Dynamics: See Summary

Similar Associations:

  • Fagus grandifolia - Quercus alba / Ilex opaca var. opaca / Athyrium filix-femina ssp. asplenioides Forest (CEGL007208)--is presumably the analogous West Gulf Coastal Plain type.

  • Fagus grandifolia - Magnolia grandiflora - Pinus glabra - (Magnolia macrophylla) / (Illicium floridanum) / Hexastylis arifolia Forest (CEGL007460)--is a beech-magnolia forest rather than a beech-white oak forest.

  • Fagus grandifolia - Quercus alba - Liquidambar styraciflua - (Liriodendron tulipifera) Forest (CEGL007209)--is a related type of the loess bluffs from Kentucky to Mississippi.

Synonymy:

  • IA8d. Southern Mixed Hardwood Forest (Allard 1990) B. in part

Comments: From Monk et al. (1989). This vegetation grades up into forests on upper slopes and ridges which contain Quercus falcata, Quercus stellata, Pinus taeda, and Juniperus virginiana. This association has been documented from steep slopes of loess-derived soils in the Homochitto National Forest of Mississippi. This association should be compared to Fagus grandifolia - Quercus alba / Ilex opaca var. opaca / Athyrium filix-femina ssp. asplenioides Forest (CEGL007208), which is described from the West Gulf Coastal Plain. Possibly the most significant difference between the West Gulf Coastal Plain and East Gulf Coastal Plain types is the occurrence of Hexastylis arifolia which is not known from either Texas (Hatch et al. 1990) or western Louisiana (Thomas and Allen 1996).

Acid Hardwood Slope Forests


Sand Laurel Oak - Southern Magnolia - (Pignut Hickory, Sand Hickory) / Farkleberry / Longleaf Spikegrass Forest


Element Identifiers

NVCS association: Quercus hemisphaerica - Magnolia grandiflora - Carya (glabra, pallida) / Vaccinium arboreum / Chasmanthium sessiliflorum Forest

Database Code: CEGL004788

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

Alliance: QUERCUS HEMISPHAERICA - CARYA GLABRA FOREST ALLIANCE (I.C.2.N.a.5)

Element Concept

Summary: This association covers slope forests associated with stream bluffs in the southern Coastal Plain, with Quercus hemisphaerica, Pinus taeda, Magnolia grandiflora, Carya glabra, Carya pallida, and Quercus nigra. In addition, Quercus hemisphaerica is common in all strata. Typical shrubs and small trees include Persea borbonia, Persea palustris, Symplocos tinctoria, and Vaccinium arboreum. Common shrubs are Vaccinium arboreum, Vaccinium stamineum, and Serenoa repens. Typical herbs include Chasmanthium laxum, Mitchella repens, Elephantopus elatus, and Dichanthelium commutatum. This community is associated with sandridges along major rivers and on slopes along small streams.

Environment: This association covers slope forests associated with stream bluffs in the southern Coastal Plain. This community is associated with sand ridges along major rivers and on slopes along small streams.

Vegetation: Stands of this association have diverse canopies dominated by Quercus hemisphaerica, Pinus taeda, Magnolia grandiflora, Carya glabra, and Quercus nigra. In addition, Quercus hemisphaerica is common in all strata. Typical shrubs and small trees include Persea borbonia, Persea palustris, Symplocos tinctoria, and Vaccinium arboreum. Common shrubs are Vaccinium arboreum, Vaccinium stamineum, and Serenoa repens. Typical herbs include Chasmanthium laxum, Mitchella repens, Elephantopus elatus, and Dichanthelium commutatum. Some additional species in this association at Apalachicola National Forest are Quercus alba, Ilex opaca, Cornus florida, Osmanthus americanus, Asimina parviflora, Pinus glabra, Hamamelis virginiana, Sabal palmetto, Ilex vomitoria, Vaccinium elliottii, Smilax pumila, Ostrya virginiana, Aristolochia serpentaria, Morus rubra, and Liquidambar styraciflua. At Little Ocmulgee State Park, Georgia, this is has been called Laurel Oak - Sand Hickory Dry Forest (T. Govus pers. comm.). This forest type occurs downslope and in slightly more protected sites than the exposed sandhills habitat. It is the second most frequently encountered plant community at Little Ocmulgee State Park. The canopy is dominated by a nearly even mixture of Quercus hemisphaerica and Carya pallida, but also includes Quercus alba, Nyssa sylvatica, Magnolia grandiflora, and Pinus taeda. The shrub and understory stratum is generally well developed and somewhat dense including Osmanthus americanus, Ostrya virginiana, Vaccinium arboreum, Hamamelis virginiana, Ilex opaca, Asimina parviflora, Gaylussacia frondosa, Vaccinium stamineum, Vaccinium pallidum, Hypericum hypericoides, Lyonia mariana, and Vaccinium tenellum. The herbaceous layer is very poorly developed in large part due to the dense, primarily evergreen, canopy that reduces light resources for these plants. Smilax pumila, Mitchella repens, and Vitis rotundifolia are the only frequently encountered herbaceous or vine species occurring within this community type.

Dynamics: This community is in sites which are naturally protected from fire.
