Carex scirpoidea Alkaline Cliff Sparse Vegetation | NatureServe Biotics 2019

Name: Carex scirpoidea Alkaline Cliff Sparse Vegetation Reference: NatureServe Biotics 2019 Description: This sparsely vegetated cliff association occurs in subboreal settings of northern New England, New York, and adjacent Canadian provinces, where weathering of calcium-bearing rock creates calcareous conditions. It is usually found above 305 m (1000 feet) elevation. The vertical cliffs may be composed of alkaline bedrock such as limestone, but this vegetation can also be found on cliffs where the matrix rock is acidic (e.g., schists or even granite), either where local inclusions weather to more nutrient-rich conditions or where fractures conduct more nutrient-rich seepage waters. These cliffs are mostly dry, but may contain small areas of seepy conditions, with associated floristic variation. The patchy vegetation is restricted to cracks and crevices, and can vary from well-vegetated to barren across the cliff face. It is a mixture of scrubby trees and shrubs, herbaceous plants, and bryoids. This association is differentiated from other northeastern cliff associations by the combination of a subboreal setting (as evidenced by the woody plants within and surrounding this vegetation: <i>Picea rubens, Alnus viridis, Acer spicatum</i>, etc.) and the presence of calciphiles such as <i>Dryopteris fragrans, Dasiphora fruticosa ssp. floribunda</i>, and <i>Campanula rotundifolia</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:35156-{8E05F0EC-6C0F-4848-BF2F-44E0C0E2734F} Plot-observations of this Community Concept: 0
