Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Slash Pine - Pond-cypress / Tall Pinebarren Milkwort - Beaksedge species Woodland
Colloquial Name: Gulf Coast Wet Slash Pine Flatwoods
Hierarchy Level: Association
Type Concept: This wet flatwoods of the western portion of the East Gulf Coastal Plain has a mixed canopy characterized by Pinus elliottii var. elliottii and Taxodium ascendens. Other canopy trees may include Nyssa biflora, Magnolia virginiana, and Acer rubrum. The understory is typically diverse and includes many species which occur as well in wet Pinus palustris savannas, but the community described here is apparently wetter. Shrubs and woody vines include Arundinaria tecta, Hypericum galioides, and Toxicodendron radicans ssp. radicans. Typical herbaceous species include Andropogon mohrii, Anthaenantia rufa, Aristida purpurascens var. virgata, Carex glaucescens, Centella erecta, Chaptalia tomentosa, Dichanthelium leucothrix, Dichanthelium scabriusculum, Eragrostis refracta, Erigeron vernus, Eriocaulon compressum, Ludwigia pilosa, Lycopodiella alopecuroides, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Panicum verrucosum, Panicum virgatum, Proserpinaca palustris, Rhynchospora gracilenta, Rhynchospora inexpansa, Saccharum giganteum, Sarracenia alata, Viola x primulifolia, Woodwardia areolata, and Xyris fimbriata. Occasional ponding occurs, but the hydrology is best characterized as saturated. This community, with an open-canopy, woodland structure and species-rich ground layer, requires fire and grades into wetter and more fire-protected sites, which have a related forest community, ~Pinus elliottii - Magnolia virginiana - Taxodium ascendens - Nyssa biflora / Polygala cymosa Swamp Forest (CEGL007556)$$. These communities are known from eastern Louisiana and are likely to occur as well in southern Mississippi and probably other states farther east.
