Mid-late Successional Slash Pine Managed Forest


Element Identifiers

NVCS association: Pinus elliottii var. elliottii - (Pinus palustris) Managed Forest

Database Code: CEGL007171

Formation: Rounded-crowned temperate or subpolar needle-leaved evergreen forest

Alliance: PINUS PALUSTRIS - (PINUS ELLIOTTII) FOREST ALLIANCE (I.A.8.N.b.9)

Element Concept

Summary: This association describes Pinus elliottii var. elliottii plantations and old-field stands, on former Pinus palustris sites. Ground layer composition is highly variable and may range from substantially natural to highly altered, or very sparse, depending on management, canopy closure, and other factors. Sites representing this association can also be considered as altered versions of more natural associations; these are placed in needle-leafed evergreen woodland (II.A).

Environment: West Gulf Coastal Plain stands which are placed here 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 association 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. On dry to xeric former Pinus palustris sites, on silt loams, fine sandy loams, or silty clay loams underlain by clay of the Kisatchie Series, the soil is moderately deep with siltstone or sandstone occurring at 36-60 inches. This well-drained, very slowly permeable soil ranges from strongly to extremely acidic.

Vegetation: This broadly conceived association accommodates flatwoods and a variety of other mesic Coastal Plain environments which are dominated by mixtures of Pinus palustris and Pinus elliottii var. elliottii. This includes a variety of situations. In the West Gulf Coastal Plain, which is outside of the natural range of Pinus elliottii, 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. The herbaceous layer also varies; in younger stands, the canopy may often be too dense for the herbaceous layer to become well-developed. However, Schizachyrium scoparium-dominated ground cover may be extensive in older stands (60 years or greater in age) that have been burned and thinned. On some dry to xeric former Pinus palustris sites, this vegetation is expressed as a fairly open forest dominated by Pinus elliottii ranging from 60-80% cover. Ingrowths of Pinus echinata, Pinus taeda, and Pinus palustris may occur here, and there is a patchy subcanopy of scrubby Quercus incana and/or Quercus margarettiae; the shrub and herbaceous strata are sparse. In the Inner Coastal Plain of South Carolina (Savannah River Site), mature upland plantations placed here 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.

Similar Associations: No information

Synonymy:

  • IF3b. Plantation (Hardwood or Conifer) (Allard 1990) B. in part

  • Loamy Hills Longleaf - Slash Pine Forest. [common name]

Comments: In particular, this broadly conceived association includes various pine stands in the West Gulf Coastal Plain, which contain Pinus elliottii. This region is outside of the natural range of this species.

Conservation Ranking & Rare Species

GRank: GM (01-04-10): These are managed or manipulated stands, whose composition has been altered by management or affected by the site history. Despite this, they may either have some conservation value (as habitat for longleaf pine-related animals, or because they have a more-or-less intact ground layer), or which may be restorable to higher-quality Pinus palustris-dominated stands.

Managed or Modified Forests


Turkey Oak Xeric Sandhill Scrub


Element Identifiers

NVCS association: Quercus laevis / (Andropogon virginicus, Aristida spp., Schizachyrium scoparium) Woodland

Database Code: CEGL004689

Formation: Cold-deciduous woodland

Alliance: QUERCUS LAEVIS WOODLAND ALLIANCE (II.B.2.N.a.17)

Element Concept

Summary: This association includes Quercus laevis-dominated vegetation on deep sandy soils of the southeastern Coastal Plain. These stands most often occur where Pinus palustris has been removed and/or failed to regenerate due to fire suppression or other environmental modifications, including turpentining and logging. The typically open canopy of stands of this vegetation type may have minor amounts of relict or regenerating Pinus palustris present. However, canopy closure of some examples may exceed 60%. The relative density and diversity of the shrub and herb layers will vary with degree of fire suppression; the local expression will vary with latitude and the distributions of various shrub and herbaceous components, as well as with soil texture. Typical herbs are indicative of very dry or xeric moisture conditions, such as Cnidoscolus stimulosus, Pityopsis graminifolia, and Callisia graminea. Cladonia and Cladina spp. may be prominent in many examples.

Environment: This vegetation type includes modified and/or fire-suppressed examples of Pinus palustris - Quercus spp.-dominated vegetation, where Pinus palustris has been removed and/or failed to regenerate due to fire suppression or other environmental modifications, including turpentining and logging.

Vegetation: The ground layer may contain a range of species given the fairly wide geographic range of this type. Grasses may include Aristida lanosa, Aristida stricta (within its range), Aristida beyrichiana (within its range), Andropogon virginicus, or Schizachyrium scoparium. Some other typical herbs may include Cnidoscolus stimulosus, Pityopsis graminifolia, and Callisia graminea. Cladonia spp. may be a prominent component in sandhill examples.

  • Sandhills, Turkey Oak Phase (Monk 1968)

  • Southern Scrub Oak: 72 (Eyre 1980) B. in part

Comments: This association was purposely created on parts of the Apalachicola National Forest years ago for "wildlife management" reasons in linear strips. In many cases these areas have better ground cover composition than adjacent pine stands which were heavily site prepped (causing heavy declines in herbaceous species) (R.E. Evans pers. obs.).
