CEGL008493 Pinus echinata - Pinus taeda - Quercus (alba, stellata) / Oxydendrum arboreum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Shortleaf Pine - Loblolly Pine - (White Oak, Post Oak) / Sourwood Forest
Colloquial Name: East Gulf Coastal Plain Shortleaf Pine - Loblolly Pine Forest
Hierarchy Level: Association
Type Concept: This shortleaf pine - loblolly pine forest association occurs in the Upper East Gulf Coastal Plain, and apparently adjacent areas of the East Gulf Coastal Plain and Piedmont. The canopy is characterized by the presence of both Pinus echinata and Pinus taeda. A mixture of hardwood species are also present, such as Quercus alba, Quercus stellata, Carya tomentosa, Carya glabra, Quercus falcata, and Quercus velutina. In addition to overstory species, the subcanopy includes Cornus florida, Oxydendrum arboreum, Nyssa sylvatica, and Liquidambar styraciflua. The patchy shrub layer includes Vaccinium elliottii, Asimina parviflora, Aesculus pavia, Hamamelis virginiana, and Arundinaria gigantea. This community has a sparse herbaceous layer including Piptochaetium avenaceum, Chasmanthium sessiliflorum, Elephantopus tomentosus, Hexastylis arifolia, Iris verna, Rudbeckia fulgida, Solidago juncea, Euphorbia pubentissima, and Mitchella repens.

Classification Comments: Some stands assigned here may exhibit greater dominance by Pinus taeda rather than Pinus echinata. To an extent, this may be simply natural variation within the type, but beyond some threshold, dominance by Pinus taeda may represent a symptom of lower community quality. This type was originally based on vegetation observed at Reed Brake Research Natural Area (Talladega National Forest), Alabama. Beckett and Golden (1982) documented eight community types from the same area, but their data do not clearly document this community.

Floristics: The open canopy is characterized by the presence of both Pinus echinata and Pinus taeda. A mixture of mesic hardwoods includes Quercus alba, Quercus stellata, Carya tomentosa (= Carya alba), Carya glabra, Quercus falcata, and Quercus velutina. In addition to overstory species, the subcanopy includes Cornus florida, Oxydendrum arboreum, Nyssa sylvatica, and Liquidambar styraciflua. The patchy shrub layer includes Vaccinium elliottii, Asimina parviflora, Aesculus pavia, Hamamelis virginiana, and Arundinaria gigantea. This community has a sparse herbaceous layer, including Piptochaetium avenaceum, Chasmanthium sessiliflorum, Elephantopus tomentosus, Hexastylis arifolia, Iris verna, Rudbeckia fulgida, Solidago juncea, Euphorbia pubentissima, and Mitchella repens.
Dynamics: The total and relative density of the overstory may be altered by a number of factors. For example, Southern Pine Beetle (Dendroctonus frontalis) damage was noted in a plot attributed to this type (NatureServe Ecology unpubl. data). Southern Pine Beetle may decimate the pine overstory or heavily reduce it. Selective logging or thinning may also alter the ratio of pines to hardwoods in stands. In some instances following the removal of the commercially valuable species, and in the absence of fire, stands could become populated with successional hardwoods (e.g., Liquidambar styraciflua, Nyssa sylvatica) as well as less fire-adapted pines (Pinus taeda). Fire suppression inhibits the reproduction of Pinus echinata and Quercus alba.
Environmental Description: This forest occurs on sites with intermediate moisture status. The best documented example occurs on a southwest-facing, somewhat steep, lower slope in the Coastal Plain of Alabama (NatureServe Ecology unpubl. data).
Geographic Range: This community occurs in the Upper East Gulf Coastal Plain of Alabama and Mississippi and is apparently found in adjacent areas of southeastern Louisiana and in the Piedmont of Alabama. More information is needed to determine the possible occurrence of this type in Georgia and Florida.
