Pinus rigida - Quercus stellata / Andropogon gerardii - Packera paupercula Woodland
Translated Name: Pitch Pine - Post Oak / Big Bluestem - Balsam Groundsel Woodland
Common Name: Southern Blue Ridge Ultramafic Woodland (Prairie Type)
Unique Identifier: CEGL004968
Classification Approach: International Vegetation Classification (IVC)
Summary: This association represents upland ultramafic woodlands of the Southern Blue Ridge of Virginia. Examples are typified by an open canopy dominated by Pinus rigida, Quercus stellata, Pinus strobus, with lesser amounts of Acer rubrum, Betula lenta, Quercus rubra, and Prunus serotina var. serotina. Dry rocky openings which support grassland vegetation are scattered throughout. Dominants include Andropogon gerardii, Schizachyrium scoparium, Packera paupercula (= Senecio pauperculus), and Pteridium aquilinum var. latiusculum. Other species include Spiraea alba var. latifolia (= Spiraea latifolia), Sorghastrum nutans, Ceanothus americanus, Zigadenus leimanthoides, Liatris pilosa (= Liatris graminifolia), Sanguisorba canadensis, Asclepias verticillata, Thalictrum revolutum, Zizia aptera, and Cladonia spp.

NatureServe Conservation Status
Global Status: G1 (23Jan2000)
Rounded Global Status: G1 - Critically Imperiled
Reasons: This community type is documented only from The Glades, Grayson County, Virginia. It is restricted to an unusual edaphic situation, i.e., outcrops of ultramafic rock in the Southern Blue Ridge, and is unlikely to be found to be more common. Total area covered by this community is less than 40 hectares (less than 100 acres). Known examples are not protected and are vulnerable to alteration or destruction.
