The Limestone Glades and Barrens of West Virginia

Cedar glade, limestone barren, and glade woodland communities are reported from limestone terranes in the Ridge and Valley of northeastern West Virginia. The cedar glade communities are dominated by Bouteloua curtipendula, Solidago arguta var. harrisii, Paronychia virginica, and Monarda fistulosa var. brevis, limestone barren communities by Bouteloua, Hystrix patula, and Schizachyrium scoparius, and glade woodlands by Juniperus virginiana, Quercus muehlenbergii, and Cercis canadensis. Drought stress appears to play a role in determining the vegetation of these areas. The flora of these three communities consists of 202 known species, including 24 considered to be rare in West Virginia and eight Appalachian shale barren endemics. Monarda fistulosa var. brevis appears to be endemic to cedar glades, limestone barrens, glade woodlands and dry limestone cliffs of West Virginia and Virginia. Six other species are almost completely restricted in West Virginia to these communities; Ophioglossum engelmannii and Senecio plattensis are reported from West Virginia for the first time. The unique flora of these communities in West Virginia suggests that they apparently originated independently of cedar glade communities of the Interior Low Plateaus.
