Common (Translated Scientific) Name: American Beech - Hickory species / (Box-elder, Bigleaf Magnolia, Appalachian Basswood) Floodplain Forest
Colloquial Name: East Gulf Coastal Plain Beech Floodplain Forest
Hierarchy Level: Association
Type Concept: The canopy of stands of this floodplain forest of the East Gulf and Upper East Gulf coastal plains is strongly dominated by Fagus grandifolia. Other canopy trees include Carya ovalis, Carya carolinae-septentrionalis, and Ulmus americana. The subcanopy may contain Acer negundo, Magnolia macrophylla, and/or Tilia americana var. heterophylla, but any of these species may not be present in all examples, as their ranges rarely overlap. Stands would typically contain lower coverage of other hardwoods typical of upper floodplain terraces in this region, such as Liquidambar styraciflua, Quercus michauxii, Quercus nigra, and Quercus shumardii. Shrubs include Halesia diptera, Ulmus alata, Arundinaria gigantea (which may have high cover), Sabal minor, Toxicodendron radicans, Bignonia capreolata, Parthenocissus quinquefolia, and Lindera benzoin. Some herbs include Trillium decipiens, Carex granularis, Arisaema dracontium, Arisaema triphyllum, Dioscorea quaternata, Maianthemum racemosum, Eupatorium fistulosum, Botrychium virginianum, Onoclea sensibilis, Pleopeltis polypodioides, Polystichum acrostichoides, and Geranium maculatum.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features:
Classification Comments: Liriodendron tulipifera and Betula nigra may be present in stands of this community, but they are not characteristic species.

Floristics: This floodplain forest of the East Gulf and Upper East Gulf coastal plains is strongly dominated by Fagus grandifolia. Other canopy trees include Carya ovalis, Carya carolinae-septentrionalis, and Ulmus americana. The subcanopy of examples from Fort Benning, Georgia, contains Acer negundo, Magnolia macrophylla, and Tilia americana var. heterophylla, but any of these species may not be present in all examples, as their ranges rarely overlap. For example, Tilia americana var. heterophylla ranges south down the Chattahoochee River but is absent from parts of the putative range of this type to the east and west. Stands could contain lower coverage of other hardwoods typical of upper floodplain terraces in this region, such as Liquidambar styraciflua, Quercus michauxii, Quercus nigra, and Quercus shumardii. Although they may be present, Liriodendron tulipifera and Betula nigra are not characteristic of this community. Shrubs include Halesia diptera, Ulmus alata, Arundinaria gigantea (which may have high cover), Sabal minor, Toxicodendron radicans, Bignonia capreolata, Parthenocissus quinquefolia, and Lindera benzoin. Some herbs include Trillium decipiens, Carex granularis, Arisaema dracontium, Arisaema triphyllum, Dioscorea quaternata, Maianthemum racemosum, Eupatorium fistulosum, Botrychium virginianum, Onoclea sensibilis, Pleopeltis polypodioides, Polystichum acrostichoides, and Geranium maculatum.

Confidence Level Comments:
Grank: G3G4
Greasons: The full range of this association is poorly known, but appears to be rare. Its potential area of occurrence is in the East Gulf and Upper East Gulf coastal plains. Beech-dominated floodplains seem to be uncommon on the landscape and to exhibit strong regional floristic variation. Additional information is needed to clarify the taxonomy and conservation status of this community type.
