Name: Minuartia groenlandica - Paronychia argyrocoma - Saxifraga michauxii Outcrop Barrens
Reference: NatureServe Biotics 2019
Description: This community is known from only two sites in the Virginia Blue Ridge. The type occupies open, convex, rocky summits at elevations of about 1200 m (3950 feet) on Buffalo Mountain and 1170 m (3850 feet) on Spy Rock. The moisture regime of these sites is xeric, and soil development is limited to shallow accumulations of disintegrated rock and humus. The community is characterized by herbaceous vegetation with very low species richness. A few small (&lt;0.5 m tall) individuals of <i>Kalmia latifolia, Rhododendron catawbiense</i>, and <i>Vaccinium pallidum</i> are present, contributing &lt;1% cover. Total herbaceous cover varies from 5-40%, with plants rooting in crevices, moss, and thin soil deposits. <i>Minuartia groenlandica</i> and <i>Paronychia argyrocoma</i> form locally abundant mats or cushions.
