Name:
Pinus elliottii - Taxodium ascendens Saturated Woodland Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
This alliance encompasses wet flatwoods with relatively frequent fire, saturated with occasional ponding, of the southeastern Coastal Plain. The mixed canopy is dominated by Pinus elliottii var. elliottii and Taxodium ascendens. Other canopy trees may include Nyssa biflora, Magnolia virginiana, Persea palustris, and Acer rubrum. The understory is typically diverse and includes many species which occur as well in wet Pinus palustris savannas, but the alliance described here is apparently wetter than this vegetation. Shrubs and woody vines can include Arundinaria gigantea ssp. tecta, Hypericum brachyphyllum, Hypericum crux-andreae, Hypericum galioides, Ilex glabra, Ilex myrtifolia, Morella cerifera (= Myrica cerifera), Morella caroliniensis (= Myrica heterophylla), Smilax laurifolia, and Toxicodendron radicans ssp. radicans. Typical herbaceous species (differing in different associations) include Andropogon glomeratus var. hirsutior, Andropogon mohrii, Anthaenantia rufa, Aristida palustris, Aristida purpurascens var. virgata, Carex glaucescens, Carex striata, Centella erecta, Chaptalia tomentosa, Dichanthelium leucothrix, Dichanthelium scabriusculum, Eragrostis refracta, Erigeron vernus, Eriocaulon compressum, Eriocaulon decangulare var. decangulare, Ludwigia pilosa, Lycopodiella alopecuroides, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Panicum verrucosum, Panicum virgatum, Proserpinaca palustris, Rhynchospora gracilenta, Rhynchospora inexpansa, Rhynchospora spp., Saccharum giganteum, Sarracenia alata, Sarracenia minor, Sporobolus pinetorum, Viola X primulifolia, Woodwardia areolata, Woodwardia virginica, and Xyris fimbriata. Occasional ponding occurs, but the hydrology is best characterized as saturated. This alliance has an open canopy, woodland structure, and species-rich ground layer. It requires fire and grades into vegetation of wetter and more fire-protected sites, which would be placed in a related forest alliance, the I.C.3.N.d Pinus elliottii - Magnolia virginiana - Nyssa biflora - (Taxodium ascendens) Saturated Forest Alliance (A.441).
