Name: Vaccinium spp. / Danthonia spicata - Solidago puberula Sparse Vegetation Reference: Eastern Ecology Working Group of... Description: This sparsely vegetated community is found on resistant outcrops of acidic bedrock along shores in the northern Appalachian Mountains and perhaps adjacent Canada. Substrates include schists, granite, quartzite, sandstone, and gneiss outcrops on rivershores, streamshores, and some lakeshores. Most are flooded annually at high water; this helps to maintain open conditions and also provides silt that accumulates in the rock crevices. The annual disturbance pattern of flooding and ice-scour restricts the vegetation to tough crevice-rooting herbs and low shrubs. Exotic species may be common in these habitats. The total vegetation cover is often less than 20%. Characteristic species include low heaths such as <i>Vaccinium angustifolium, Vaccinium myrtilloides, Vaccinium pallidum</i>, or <i>Gaylussacia baccata</i>, and herbs such as <i>Sibbaldiopsis tridentata (= Potentilla tridentata), Juncus tenuis, Hieracium</i> spp., <i>Deschampsia caespitosa, Trisetum spicatum, Symphyotrichum novi-belgii (= Aster novi-belgii), Solidago simplex var. racemosa (= Solidago glutinosa var. racemosa), Poa compressa, Danthonia spicata, Deschampsia flexuosa</i>, and <i>Andropogon gerardii</i>. Bryoids are sparse, except for certain flood-resistant moss and lichen species. This community is distinguished from other shoreline outcrop associations by the lack of circumneutral or calcareous indicator herbs.  Accession Code: VB.CC.31089.CEGL006531 Plot-observations of this Community Concept: 0
