This community develops on primary successional bars along major alluvial rivers.

Element Sources References: Riverfront and Levee Forests and Shrublands Gulf Coast Live Oak Levee ForestElement Identifiers NVCS association: Quercus virginiana - (Pinus taeda) / (Sabal minor, Serenoa repens) Forest Database Code: CEGL007039 Formation: Temporarily flooded temperate seasonal evergreen forest Alliance: QUERCUS VIRGINIANA TEMPORARILY FLOODED FOREST ALLIANCE (I.A.4.N.e.1) Element Concept Summary: This is a broadly described association ranging from the Atlantic Coastal Plain of Georgia and possibly South Carolina to the Gulf Coastal Plain of Texas. It includes floodplain forests occurring on older and more recent river levees, dominated by Quercus virginiana. Pinus taeda is codominant in the overstory of some occurrences and present in most. Conspicuous components of the shrub layer include Sabal minor and Serenoa repens (within its range). Additional information is needed to fully describe this association. Environment: This association occurs on temporarily flooded, natural levee ridges and terraces. Vegetation: Plots from the Osceola National Forest document this association as follows. The canopy is codominated by Quercus virginiana and Pinus taeda or Quercus nigra. Other canopy species are Acer rubrum, Betula nigra, Quercus laurifolia, and Liquidambar styraciflua. Subcanopy trees include Betula nigra, Liquidambar styraciflua, Quercus laurifolia, Acer rubrum, Quercus virginiana, Quercus nigra, Diospyros virginiana, and Nyssa biflora. The shrub layer is dominated by Serenoa repens, many of which have trunks growing 1 m (3-4 feet) high. Other shrubs are at low cover values; these include Asimina parviflora, Vaccinium elliottii, Cyrilla racemiflora, Cephalanthus occidentalis, Sebastiania fruticosa, Diospyros virginiana, Ilex opaca, and Vaccinium corymbosum. Vines include Smilax rotundifolia and Smilax walteri. Epiphytes present are Tillandsia usneoides, Tillandsia bartramii, and Pleopeltis polypodioides ssp. michauxiana (= Polypodium polypodioides var. michauxianum). Mitchella repens is the only herbaceous species documented; it was only trace. Dynamics: These forests are prone to flooding, particularly severe flooding after hurricanes. Similar Associations: No information Synonymy: No information Comments: This association needs further description with subsequent range assessment. Documented from the Aucilla River and Middle Prong St. Marys River, both in Florida. This single, broadly defined association may ultimately be split into several more narrowly define types. In Texas this community may occur along small streams and rivers at the northern periphery of the Coastal Prairie where it is contiguous with the Pineywoods. Conservation Ranking & Rare Species GRank: G3G4 (97-10-09): As currently described, this community ranges from the Atlantic Coastal Plain of Georgia and possibly South Carolina to the Gulf Coastal Plain of Texas. The range in the rank reflects the need for further inventory and description of this type. It may warrant division into two or more types. More information is needed. High-ranked species: No information Element Distribution Range: This association is currently broadly described, ranging from the Atlantic Coastal Plain of Georgia and possibly South Carolina to the Gulf Coastal Plain of Texas. In Texas, it may occur along the lower Trinity and Sabine river systems in Harris, Chambers and Jefferson counties. States: AL FL GA LA MS SC? TX?
