CEGL002423 Quercus lyrata - Carya aquatica - (Quercus texana) / Forestiera acuminata Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Overcup Oak - Water Hickory - (Nuttall Oak) / Eastern Swamp-privet Floodplain Forest
Colloquial Name: Overcup Oak - Nuttall Oak Bottomland Forest
Hierarchy Level: Association
Type Concept: This overcup oak - hardwood swamp forest is found in the Mississippi River Alluvial Plain of southeastern Missouri (and presumably Illinois) south to Louisiana and Mississippi, and west into the West Gulf Coastal Plain and adjacent ecoregions of Texas. It is distinguished from other Quercus lyrata forests of the Gulf region by the presence of Quercus texana. Stands that lack Quercus texana and have either significant amounts of Liquidambar styraciflua or Carya aquatica are covered by other types [see Similar Associations]. Stands occur on level to gently sloping bottomlands along streams and rivers or in sinkhole basins. A high water table is present. The deep soils (>100 cm) are somewhat poorly drained and are seasonally wet. The parent material is alluvium. The trees are tall (30-45 m), and the canopy is well-developed (60-100% cover). Typical dominants include Quercus lyrata, Carya aquatica, and Quercus texana (within its range). The dense shrub/sapling layer reaches heights of 8 m or more. Forestiera acuminata is among the shrubs found in stands of this type. Lianas are common. The moderately dense (20-60% cover) ground layer is composed of mixed herbaceous species.

Classification Comments: This association, and the related ~Quercus lyrata - Liquidambar styraciflua / Forestiera acuminata Floodplain Forest (CEGL002424)$$, have been compared to related associations in the Southeast (e.g., CEGL007397), and differences resolved. ~Quercus lyrata - Carya aquatica Floodplain Forest (CEGL007397)$$ was a related broad-ranging type which has been split. The portion of CEGL007397 west and north of the East Gulf Coastal Plain has been conceptually transferred to CEGL002424/CEGL002423. Quercus texana is a preferred synonym for Quercus nuttallii.

Floristics: This community is a bottomland mixed hardwoods forest. The trees are tall (30-45 m) and the canopy is well-developed (60-100% cover). Typical dominants include Quercus lyrata, Carya aquatica, and Quercus texana. Other canopy and subcanopy species include Diospyros virginiana, Gleditsia aquatica, Planera aquatica, and Crataegus opaca. The dense shrub/sapling layer reaches heights of 8 m or more. Forestiera acuminata is among the shrubs found in stands of this type. Lianas are common, including Brunnichia ovata. The moderately dense (20-60% cover) ground layer is composed of mixed herbaceous species.
Dynamics: No Data Available
Environmental Description: Stands occur on level to gently sloping bottomlands along streams and rivers. Flooding occurs during periods of heavy precipitation often resulting in ponding. A high water table is present. The deep soils (>100 cm) are somewhat poorly drained and are seasonally or intermittently wet. The parent material is alluvium.
Geographic Range: This community is found in the Mississippi River Alluvial Plain of southeastern Missouri (and presumably Illinois) south to Louisiana and Mississippi, and west into the West Gulf Coastal Plain and adjacent ecoregions of Texas.
