Name:
Pinus resinosa - Quercus rubra Woodland Alliance
Reference:
Eastern Ecology Working Group of...
Description:
This alliance has been defined to accommodate 'balds' at high elevations in eastern West Virginia, with an open canopy of Pinus resinosa and Quercus rubra, well south of the main range of Pinus resinosa. These woodlands are of limited extent and occur on west-facing side ridges of Pike Knob, Pendleton County, West Virginia, at about 1220 m (4000 feet) elevation. Canopy species include Pinus resinosa, Quercus rubra, and Betula lenta. Other woody species include Salix humilis, Physocarpus opulifolius, Vaccinium angustifolium, Symphoricarpos albus, Rosa acicularis, Sibbaldiopsis tridentata. The herb layer is dominated by Danthonia compressa and Antennaria virginica, with other species including Polypodium appalachianum, Hylotelephium telephioides (= Sedum telephioides), Phlox subulata, Potentilla canadensis, Heuchera alba, Campanula divaricata, Fragaria virginiana, Allium allegheniense, Deschampsia flexuosa, Carex pensylvanica, Polygonum tenue, Houstonia longifolia (= var. longifolia), Saxifraga virginiensis, Poa compressa, and Solidago bicolor. Rhytidium rugosum is an abundant moss. The species composition is a peculiar mix of species with different affinities: northern (Pinus resinosa, Rhytidium rugosum, Sibbaldiopsis tridentata, Vaccinium angustifolium); southern/central Appalachian endemics (Campanula divaricata, Hylotelephium telephioides); central Appalachian endemics (Antennaria virginica, Heuchera alba); northern/western (Symphoricarpos albus, Rosa acicularis).
