PINUS ELLIOTTII PLANTED FOREST ALLIANCE

Alliance Concept

Summary: This alliance includes planted stands (plantations) of Pinus elliottii var. elliottii (typically monospecific), within and outside of its natural range. These are cultivated forests and are not considered natural or semi-natural vegetation. They are maintained as plantations for the harvest of forest products (lumber, pulpwood). Stands of this alliance are primarily in uplands, but occasional stands in wetland environments are included here as well. This alliance is also supposed to include the rare case of "exotic" stands resulting from natural regeneration outside of the natural range of Pinus elliottii var. elliottii, although these are probably better accommodated as examples of Pinus elliottii var. elliottii - (Pinus palustris) Managed Forest (CEGL007711), a member of the Pinus palustris - (Pinus elliottii) Forest Alliance (A.123).

PINUS PALUSTRIS PLANTED FOREST ALLIANCE

Alliance Concept

Summary: This alliance includes young, monospecific plantation stands of Pinus palustris. These are cultivated forests which do not represent or approximate natural or near-natural vegetation structure. They are maintained as plantations for the harvest of forest products (usually poletimber). The core concept of these stands are those which are mechanically planted to dense, often perfect rows of planted Pinus palustris or otherwise dense, young stands which are managed and maintained for the extraction of forest products. Stands are typically established with mechanical planting, but may also be established through other means. In most cases these stands support almost no other tree species in the overstory, and typically very little understory.. This alliance rarely exceeds 20-40 years of age on most timberlands. Excluded from this alliance are areas where longleaf pine has been planted in ways that maintain natural ground layer components (such as hand planting with no mechanical site preparation), as well as areas which originated as mechanically planted, dense stands but which have been thinned and burned or have "broken up" with age allowing for restoration of some natural ground cover components and a canopy structure approximating that of natural longleaf pine communities. Most stands in this alliance are created after clear-cutting of natural stands and mechanical site preparation to reduce or eliminate competition for planted pine seedlings. Dense planting in rows, if successful, tends to result in nearly complete canopy closure which persists until the stand has been "thinned" twice, at which time some openings in the canopy are created which may allow some sunlight to the ground layer. Herbaceous ground cover of any kind tends to be sparse due to reduction during site preparation, the typically dense canopy cover, and to the fact that many young plantations are infrequently burned at best. Moreover, `natural' ground layer vegetation is especially lacking. In North and South Carolina, pinestraw is commonly harvested from these forests, often further damaging the ground cover.
