Name: Kalmia latifolia - Gaylussacia baccata - Vaccinium (angustifolium, pallidum) - Menziesia pilosa Shrubland
Reference: NatureServe Biotics 2019
Description: This shrubland community is restricted to high-elevation, acidic bedrock exposures in the Central Appalachians of eastern West Virginia and northwestern Virginia. It occurs on upper-slope and ridgetop outcrops, pavements, and clifftops of acidic bedrock (quartzite and granitic) at elevations from about 950 to 1460 m (3100-4800 feet). Surface cover of bedrock and loose boulders averages about 80% in plot samples, and soil development is minimal. These habitats have distinctly xeric moisture regimes and are subject to year-round microclimatic extremes, including high solar exposure and temperatures in summer, high winds, periodic ice, and low winter temperatures. <i>Kalmia latifolia, Gaylussacia baccata</i>, and <i>Vaccinium</i> spp. are codominant shrubs in variable proportions, with <i>Vaccinium angustifolium</i> the principal species of high-elevation sites (all &gt;1200 m [4000 feet]) in West Virginia and <i>Vaccinium pallidum</i> the characteristic species of somewhat lower-elevation (950-1200 [3100-4000 feet]) sites in Virginia. Other woody plants occurring frequently in the type include <i>Menziesia pilosa, Sorbus americana, Aronia melanocarpa, Gaultheria procumbens, Hamamelis virginiana, Prunus pensylvanica, Ilex montana, Ilex mucronata</i> (West Virginia only), and extremely stunted (&lt;3 m tall) <i>Betula alleghaniensis</i>. Herbaceous plants are typically very sparse, but occasional dense colonies of <i>Deschampsia flexuosa</i> occur on open ledges with thin mats of moss and organic matter. The vegetation is floristically quite depauperate and plot-sampled stands have a mean species richness of only 15 vascular taxa.
