Quercus nigra Forest Alliance | Southeastern Ecology Working Gro...
click to update datacart
Name: Quercus nigra Forest Alliance Reference: Southeastern Ecology Working Gro... Description: Upland forests dominated or codominated by Quercus nigra, in some cases as a result of disturbance and/or fire suppression of more diverse canopied forests. Forests in this alliance occur on mesic or dry-mesic sites, especially on loamy or other fine-textured soils (in contrast to the Quercus hemisphaerica Forest Alliance (A.53), which occurs primarily on coarse-textured sands in drier situations). One association is found along small streams. Stands of this alliance typically contain other Quercus spp. (e.g., Quercus falcata), Liquidambar styraciflua, and Pinus taeda. In the Upper Gulf Coastal Plain of Georgia, some examples may contain Fagus grandifolia, Liriodendron tulipifera, Carya alba, and Cornus florida in the subcanopy. In Texas, Quercus nigra dominates the canopy, with scattered Quercus virginiana. The subcanopy/shrub stratum is dense (without fire) and contains Ilex vomitoria, Vaccinium stamineum, and Vitis rotundifolia. In small stream forests of the Gulf Coast Prairies and Marshes Ecoregion and possibly adjacent areas, other shrubs and small trees include Callicarpa americana and Prunus caroliniana. Woody vines include Berchemia scandens, Parthenocissus quinquefolia, Toxicodendron radicans, and Ampelopsis arborea. Chasmanthium sessiliflorum is the dominant herb. Other herbs are Oplismenus hirtellus ssp. setarius (= Oplismenus setarius), Carex cherokeensis, Verbesina virginica, Ageratina aromatica, Asplenium platyneuron var. platyneuron, Geum canadense, and Polygonum virginianum. Tillandsia usneoides and Pleopeltis polypodioides ssp. michauxiana are common epiphytes. This alliance appears to be more abundantly represented (or more 'natural') towards the western end of the Coastal Plain.  Accession Code: VB.CC.28449.QUERCUSNIGRAFOR Plot-observations of this Community Concept: 0
