Name: Pinus palustris - (Pinus elliottii) Forest Alliance Reference: Southeastern Ecology Working Gro... Description: This alliance accommodates flatwoods and other mesic Coastal Plain environments dominated by mixtures of Pinus palustris and Pinus elliottii var. elliottii. This includes a variety of situations, for example dense, fire-suppressed Pinus elliottii var. elliottii plantations and old-field stands, on former Pinus palustris sites, with a remnant semi-natural ground layer; in addition to other silviculturally manipulated stands, such as forests resulting from planting or regeneration of Pinus elliottii var. elliottii from seed trees. Examples of this alliance are generally silviculturally managed, so some examples at particular times may exhibit canopy coverage below the 60% cover limit for a forest, but all examples are conceptually included here. Burning frequencies for management purposes are generally increased in older stands (greater than 15 years of age). Examples of this alliance in the West Gulf Coastal Plain include stands which are old plantations planted outside the natural range of Pinus elliottii var. elliottii, sometimes on former Pinus palustris sites. In this region, the local expression of this alliance depends on soil conditions. In mesic to dry-mesic uplands, the canopy may range from nearly pure Pinus elliottii (possibly with some Pinus taeda ingrowth) to a mixed canopy containing Pinus elliottii var. elliottii and Pinus palustris in combination. In the former case, soils are generally acidic silt loams and sandy loams; in the latter case they tend to be well-drained to moderately well-drained fine sandy loams and sands underlain by clay. The understory and herbaceous strata vary depending on management, site conditions, and canopy coverage; the tall-shrub stratum ranges from fairly dense to sparse, and may be patchy. In the Inner Coastal Plain of South Carolina (Savannah River Site), mature upland plantations in this alliance tend to develop an understory including Nyssa sylvatica and an herbaceous stratum dominated by Rubus argutus. In contrast, burned examples tend to have Prunus serotina var. serotina in the understory and Andropogon virginicus in the herbaceous layer.  Accession Code: VB.CC.28464.PINUSPALUSTRISP Plot-observations of this Community Concept: 0
