CEGL008577 Magnolia grandiflora / Prunus caroliniana - Carpinus caroliniana / Arundinaria gigantea Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Southern Magnolia / Carolina Laurel Cherry - American Hornbeam / Giant Cane Forest

Colloquial Name: Texas Upper West Gulf Coastal Plain Southern Magnolia Forest

Hierarchy Level:  Association

Type Concept: This is a mostly evergreen-dominated hardwood forest found along the periphery of the West Gulf Coastal Plain of eastern Texas. It is only known from a very limited area near the western distributional limits of several tree species including Fagus grandifolia on unusually rich soils. The canopy is dominated by Magnolia grandiflora, with lesser amounts of Quercus nigra, Liquidambar styraciflua, and Quercus pagoda present. Midstory trees are prevalent, with Carpinus caroliniana ssp. caroliniana and Ostrya virginiana being most important, and possibly indicative of the rich, high pH soils. A relatively sparse shrub stratum is present, but no species in this stratum are diagnostic of this type. A sparse herbaceous stratum is also present amidst dense hardwood leaf litter.

Floristics: The canopy is dominated by Magnolia grandiflora, Quercus nigra, Liquidambar styraciflua, and Quercus pagoda. Other woody species found predominately in the subcanopy include Carpinus caroliniana ssp. caroliniana, Ilex opaca, Cercis canadensis, Morus rubra, and Nyssa sylvatica. The midstory is strongly dominated by Prunus caroliniana, with Halesia diptera, Ilex vomitoria, Callicarpa americana, and Sabal minor also present. Arundinaria gigantea dominates the understory. Other understory species include Carex abscondita, Oplismenus hirtellus, Carex amphibola, Carex cherokeensis, Mitchella repens, Sambucus nigra ssp. canadensis, and other species (Turner et al. unpubl. data).

Dynamics:  No Data Available

Environmental Description:  This community has been documented from an areas mapped as Bernaldo soils on Quaternary alluvium in the Coastal Plain of eastern Texas. Soil pH tested extremely high (8.1) with equally high levels of calcium and magnesium present in soil samples. Texturally, these soils were 61% clay. (Turner et al. unpubl. data).

Geographic Range: This community is known only from eastern Texas. There is a small chance this type may range into western Louisiana, but this is unlikely given the unusual environment it is found in Texas.
