CEGL004771 Quercus phellos - Quercus nigra - Quercus alba / Chasmanthium (laxum, sessiliflorum) Floodplain Forest

Type Concept Sentence: This temporarily flooded forest dominated by Quercus phellos or Quercus nigra with possibly considerable Liquidambar styraciflua is common along small floodplains in the East Gulf Coastal Plain of the southeastern United States.


Common (Translated Scientific) Name: Willow Oak - Water Oak - White Oak / (Slender Woodoats , Longleaf Woodoats) Floodplain Forest

Colloquial Name: East Gulf Coastal Plain Oak Small Stream Floodplain Forest

Hierarchy Level:  Association

Type Concept: This forest is common along small floodplains in the East Gulf Coastal Plain of Mississippi, Alabama, Georgia, and possibly Louisiana. Quercus phellos or Quercus nigra may dominate this temporarily flooded forest; some stands may contain considerable Liquidambar styraciflua, and Quercus alba may be present. Some other associated species include Pinus glabra, Pinus taeda, Quercus pagoda, Quercus alba, Quercus laurifolia, Quercus similis, Ulmus alata, Carya tomentosa, Carya glabra, Carya ovata, Nyssa biflora, and others. Occurrences often have many species in the canopy, and variability of species composition from occurrence to occurrence may be relatively large. The subcanopy/shrub stratum is well-developed and contains canopy species, as well as Crataegus viridis, Chionanthus virginicus, Acer rubrum, Vaccinium elliottii, Ilex decidua, Ilex vomitoria, Vaccinium stamineum, Cornus florida, Sabal minor, Sambucus nigra ssp. canadensis, Crataegus marshallii, Arundinaria gigantea, and others. Some woody vines present. The herbaceous layer also may contain many species with no clear dominants.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Documented from the Bienville National Forest, Mississippi (M. Pyne, S. Landaal 8-97), the Talladega National Forest (Oakmulgee Ranger District), and the Tuskegee National Forest (August 2000). The exotics Lonicera japonica and Ligustrum sinense may be present in some stands of this association. Some stands assigned here (e.g., plot TALO.3 -Compartment 10 #3) contain Magnolia virginiana and Acer rubrum in the understory and seem "transitional" to a saturated forest (e.g., ~Magnolia virginiana - Nyssa biflora / Carpinus caroliniana / Thelypteris noveboracensis - Athyrium filix-femina Swamp Forest (CEGL004722)$$).

Floristics: Quercus phellos and/or Quercus nigra may dominate this temporarily flooded forest; some associated canopy species include Pinus glabra, Pinus taeda, Quercus pagoda, Quercus alba, Quercus laurifolia, Quercus similis, Ulmus alata, Carya tomentosa (= Carya alba), Carya glabra, Carya ovata, Nyssa biflora, Liquidambar styraciflua, and others. Occurrences often have many species in the canopy, and variability of species composition from occurrence to occurrence may be relatively large. A stand placed here from the Tuskegee National Forest (Macon County, Alabama) additionally contains substantial Liriodendron tulipifera and Magnolia virginiana in the canopy and subcanopy. The subcanopy/shrub stratum is well-developed and contains canopy species, as well as Crataegus viridis, Chionanthus virginicus, Acer rubrum, Vaccinium elliottii, Ilex decidua, Ilex vomitoria, Vaccinium stamineum, Cornus florida, Sabal minor, Sambucus nigra ssp. canadensis (= Sambucus canadensis), Crataegus marshallii, Arundinaria gigantea, and others. Some woody vines present include Berchemia scandens, Bignonia capreolata, Gelsemium sempervirens, Parthenocissus quinquefolia, Smilax bona-nox, Smilax glauca, Smilax rotundifolia, Toxicodendron radicans, and Vitis rotundifolia. The herbaceous layer also may contain many species with no clear dominants. Among the species that may be present in this stratum are Chasmanthium sessiliflorum, Elephantopus carolinianus, Scutellaria integrifolia, Uvularia sessilifolia, Pedicularis canadensis, Botrychium dissectum, Lycopus rubellus, Dichanthelium boscii, Eupatorium semiserratum, Viola x primulifolia, Mitchella repens, Carex sp. (Carex joorii?, Carex glaucescens?), and others. In the Tuskegee National Forest stand assigned here, some additional herbs include Chasmanthium laxum (dominant), Dioscorea quaternata, Athyrium filix-femina ssp. asplenioides, Woodwardia areolata, Dichanthelium sp., Osmunda regalis, Scleria sp., Sanicula canadensis, Onoclea sensibilis, Ruellia caroliniensis, and Thaspium barbinode. The exotics Lonicera japonica and Ligustrum sinense may be present in some stands of this association.
