Name: Pinus banksiana - Pinus strobus - (Quercus rubra) / Cladina spp. Nonvascular Vegetation Reference: Midwestern Ecology Working Group... Description: This granite/metamorphic rock outcrop is found in rocky openings on and near the Canadian Shield in the northern Great Lakes region of the United States and Canada, and possibly in northern New England. Stands are typically comprised of granite or metamorphic rock, and possibly basalt. They occur on relatively level or rounded areas of exposed bedrock, sometimes along lake shorelines, including the Great Lakes shorelines. Soil development is minimal, and pH is typically acid. Occurrences are typically a mosaic of exposed bedrock with patches of low vegetation dominated by fruticose lichens and mosses (which cover about 40% of the area) and scattered trees and shrubs (which rarely exceed 20% cover). Bare rock (with crustose lichens) covers about 30% of the area. Lichen species include Cladina rangiferina (= Cladonia rangiferina) and Cladina mitis (= Cladonia mitis). Mosses include Dicranum spp., Pleurozium schreberi, and Polytrichum spp. The vascular vegetation is typically sparse. Scattered trees and shrubs include Amelanchier spp., Diervilla lonicera, Juniperus communis, Pinus banksiana, Pinus resinosa, Pinus strobus, Prunus pensylvanica, Quercus rubra, Salix bebbiana, and Vaccinium angustifolium. The sparse herbaceous layer includes Agrostis hyemalis, Aralia hispida, Campanula rotundifolia, Corydalis sempervirens, Danthonia spicata, Deschampsia caespitosa, Chamerion angustifolium (= Epilobium angustifolium), Poa compressa, and Sibbaldiopsis tridentata (= Potentilla tridentata).  Accession Code: VB.CC.22108.PINUSBANKSIANAP Plot-observations of this Community Concept: 0
