CEGL004130 Quercus sinuata var. sinuata - Ulmus crassifolia / Sabal minor Red River Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bastard Oak - Cedar Elm / Dwarf Palmetto Red River Floodplain Forest
Colloquial Name: Red River High Bottomland Forest
Hierarchy Level: Association
Type Concept: This is a temporarily flooded bottomland forest that occurs in bottomlands along the Red River in Arkansas and probably adjacent areas of Oklahoma and Texas. No high-quality occurrences are known; this description is from degraded remnants. Soils are deep, somewhat poorly drained, level and nearly level clay soils on broad flats on the Red River (Holocene backswamp geomorphology). Surface is circumneutral to mildly alkaline, and subsurface is moderately alkaline with some calcium carbonate concretions. Hydric indicators, including mottles, are present; intersecting slickensides indicate potential gilgai topography. In dry conditions, cracks (up to 2 inches wide) extend to a depth of 20 inches. Quercus sinuata dominates along with Ulmus crassifolia. Other common species include Quercus phellos, Quercus macrocarpa, Quercus laurifolia, Quercus falcata, Quercus shumardii, Ulmus americana, Acer saccharinum, and Celtis laevigata. The structure of stands is an open forest or woodland with grass, sedge and Sabal minor ground layer.

Environmental Description: This temporarily flooded bottomland forest occurs in bottomlands along the Red River in Arkansas and probably adjacent areas of Oklahoma and Texas. Soils (Billyhaw: very fine, montmorillonitic, thermic, Typic Ochraquults) are deep, somewhat poorly drained, level and nearly level clay soils on broad flats on the Red River (Holocene backswamp geomorphology). Surface is circumneutral to mildly alkaline, and subsurface is moderately alkaline with some calcium carbonate concretions. Hydric indicators, including mottles, are present; intersecting slickensides indicate potential gilgai topography. In dry conditions, cracks (up to 2 inches wide) extend to a depth of 20 inches.
Geographic Range: This forest is known only from bottomlands along the Red River in southwestern Arkansas and probably adjacent areas of Oklahoma and Texas.
