NVCS association: Quercus lyrata - Carya aquatica Forest
Database Code: CEGL007397
Formation: Seasonally flooded cold-deciduous forest
Alliance: QUERCUS LYRATA - (CARYA AQUATICA) SEASONALLY FLOODED FOREST ALLIANCE (I.B.2.N.e.13)
Element Concept
Summary: This bottomland forest ranges from the Mid-Atlantic Coastal Plain west to the East Gulf Coastal Plain. The canopy is typically dominated by Quercus lyrata and Carya aquatica. Other canopy associates may include Gleditsia aquatica, Liquidambar styraciflua, Acer rubrum var. drummondii, Taxodium distichum, Populus deltoides, and Diospyros virginiana. Shrubs include Planera aquatica, Cornus foemina (= Cornus stricta), and Cephalanthus occidentalis. Subcanopy, shrub, herbaceous, and vine density and diversity are directly affected by the timing, duration, and depth of seasonal flooding. Herbaceous growth and diversity will be limited in areas of consistently longer hydroperiod. More detailed information is needed on the floristics and environment of this association.
Environment: Forests dominated by the nominal species may commonly occur in wet flats and on old levee ridge edges (Wharton et al. 1982). This is a community of Zone III (Wharton et al. 1982).
Vegetation: Stands are dominated by Quercus lyrata and Carya aquatica. Other canopy associates may include Gleditsia aquatica, Liquidambar styraciflua, Acer rubrum var. drummondii, Taxodium distichum, Populus deltoides , and Diospyros virginiana.

Comments: Distribution of this association was reduced because of its originally wide geographic range. The conceptual portion of this association west of the East Gulf Coastal Plain was excised and merged with Quercus lyrata - Carya aquatica - (Quercus texana) / Forestiera acuminata Forest (CEGL002423).

NVCS association: Betula nigra / Salix nigra / Hypericum prolificum - Ampelopsis arborea Forest
Database Code: CEGL007794
Formation: Temporarily flooded cold-deciduous forest
Alliance: BETULA NIGRA - (PLATANUS OCCIDENTALIS) TEMPORARILY FLOODED FOREST ALLIANCE (I.B.2.N.d.5)
Element Concept
Summary: This temporarily flooded riverfront association is found along temporarily flooded natural levees and floodplains of brownwater rivers in the East Gulf Coastal Plain, where Betula nigra-dominated vegetation occurs south of the range of Platanus occidentalis. The canopy is dominated by Betula nigra, with Liquidambar styraciflua and an occasional Pinus taeda. Quercus laurifolia may also occur in some examples. The subcanopy contains Salix nigra, Acer rubrum, Carpinus caroliniana, and Cornus foemina (= Cornus stricta). Hypericum prolificum is a prominent shrub. Vines, such as Smilax bona-nox and Ampelopsis arborea, are common. Herbs include Penthorum sedoides, Sagittaria sp., Polygonum sp., Mimulus sp., Leersia hexandra?, and Boehmeria cylindrica.
