CEGL003560 Pinus echinata / Schizachyrium scoparium Appalachian Woodland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Shortleaf Pine / Little Bluestem Appalachian Woodland

Colloquial Name: Appalachian Shortleaf Pine / Little Bluestem Woodland

Hierarchy Level:  Association

Type Concept: These fire-maintained, shortleaf pine woodlands occurred historically in the Appalachian regions of Alabama, north through Georgia, Tennessee, and Kentucky on dry ridges and slopes or rock outcrops. Almost no intact examples are known to persist, although restoration efforts are underway in the Daniel Boone National Forest, Kentucky, the Chattahoochee National Forest, Georgia, and in Great Smoky Mountains National Park, Tennessee. Stands of these woodlands are dominated by Pinus echinata, with less than 25% cover by Quercus spp. They may contain an admixture of Pinus virginiana or Pinus rigida. The canopy can range from an open forest to woodland structure. The understory is open and dominated by graminoids and forbs. This community historically provided habitat for montane populations of red-cockaded woodpecker (Picoides borealis). More information is needed to characterize and distinguish this community.

Classification Comments: This community occurs outside the range of Pinus palustris. In Great Smoky Mountains National Park, this community is being restored through the reintroduction of fire (B. Dellinger pers. comm.). There are no true remnants of this community left in Kentucky; all have Quercus spp. understory and shrubs and belong in a Pinus echinata - Quercus spp. woodland alliance (J. Campbell pers. comm.). On the very western edge of the Blue Ridge province in northern Georgia (the Cohutta Foothills), this community is being restored with the reintroduction of fire (K. Wooster pers. comm.). The current presence of related vegetation in the Cumberlands and/or the Interior Low Plateau of Kentucky and Tennessee is more speculative; in those regions, this type was probably more common historically than it is at present.

Floristics: An example of this community undergoing restoration in the western edge of the Blue Ridge, in Fannin County, Georgia, has a canopy dominated by Pinus echinata, but with significant coverage by Quercus coccinea and Quercus alba. Other woody species in the canopy and subcanopy include Pinus taeda, Pinus strobus, Nyssa sylvatica, Acer rubrum, Quercus montana (= Quercus prinus), and Oxydendrum arboreum. The shrub stratum is open, but patchy, dominated by ericaceous shrubs such as Vaccinium pallidum, Vaccinium stamineum, Vaccinium hirsutum, Vaccinium arboreum, Rhododendron alabamense, Kalmia latifolia, and Lyonia ligustrina. Other shrubs and vines include Smilax glauca, Hypericum hypericoides ssp. multicaule, and Diospyros virginiana. The herbaceous stratum is closed, but has variable local dominance. Visual dominants at this site were Schizachyrium scoparium, Pityopsis graminifolia, Pteridium aquilinum, Baptisia tinctoria, and Epigaea repens. Other herbaceous species are Iris cristata, Coreopsis major, Solidago odora, Dichanthelium commutatum, Antennaria plantaginifolia, Galax urceolata, Symphyotrichum dumosum (= Aster dumosus), Tephrosia virginiana, and Ageratina aromatica. A sample from the upper Piedmont of Georgia (Chattahoochee National Forest) which is placed here is dominated by Pinus echinata in the canopy. The subcanopy includes Juniperus virginiana var. virginiana, Quercus marilandica, Quercus stellata, Nyssa sylvatica, and Liquidambar styraciflua. Shrubs are Vaccinium arboreum, Chionanthus virginicus, Smilax glauca, and Crataegus uniflora. Herbs include Danthonia sericea, Coreopsis major, Schizachyrium scoparium, Andropogon gyrans, and Liatris microcephala. This example is adjacent to a "glade." An additional sample from the Cherokee National Forest in Monroe County, Tennessee, is a frequently burned woodland occurring on a steep slope underlain by phyllite. The canopy is dominated by Pinus echinata (10-25% cover). Other canopy components include Pinus rigida, Pinus virginiana, and Quercus alba. The open subcanopy is characterized by Quercus marilandica, Quercus alba, and Quercus stellata. The open shrub layer includes Calycanthus floridus and Ceanothus americanus. Some of the more prominent members of the dense and diverse herbaceous layer include Schizachyrium scoparium, Sorghastrum nutans, Pityopsis graminifolia, Tephrosia virginiana, Liatris scariosa, Antennaria plantaginifolia, Symphyotrichum undulatum (= Aster undulatus), Helianthus divaricatus, and Galactia volubilis.

Dynamics:  Nearby stands on similar topographic positions often have a very different composition and lack the open woodland character. In Georgia, these adjacent stands are often densely dominated by Pinus virginiana. Young Pinus strobus seedlings are becoming established underneath the canopy and are anticipated to move into the gaps caused by the dying and declining canopy species. The dense shaded environment of these stands suppresses fine fuels provided by herbaceous species and are consequently difficult to burn.

Environmental Description:  One stand attributed to this type from the Cherokee National Forest in Monroe County, Tennessee, is a frequently burned woodland occurring on a steep slope underlain by phyllite (NatureServe Ecology unpubl. data).

Geographic Range: This association occurred historically in the Appalachian regions of Alabama, north through Georgia, Tennessee, and Kentucky. Restoration efforts are underway in Georgia, Tennessee, and Kentucky.
