Name: Trichophorum cespitosum - Saxifraga (foliolosa, paniculata, rivularis) Alpine Cliff Reference: NatureServe Biotics 2019 Description: These are high-elevation cliffs that support mixtures of vegetation interspersed with rock faces. Most vegetation is confined to areas where water flows over the rock face. Trees are absent. Herbs and bryophytes are prominent, but dwarf-shrubs may be common as well. Local vegetation cover may be nearly continuous, but taken over the entire rock face it is more sparse. <i>Carex scirpoidea</i> and <i>Trichophorum cespitosum</i> are the most abundant graminoids; <i>Juncus trifidus</i> and <i>Calamagrostis canadensis</i> are frequent. Low shrubs include <i>Vaccinium uliginosum</i> and <i>Alnus viridis ssp. crispa</i>. One or more alpine herbs are the most diagnostic plants, such as <i>Saxifraga foliolosa, Saxifraga paniculata, Saxifraga rivularis, Epilobium hornemannii, Arnica lanceolata, Polygonum viviparum, Phleum alpinum</i>, and <i>Cardamine bellidifolia</i>. This association can share species with ~<i>Carex scirpoidea</i> Alkaline Cliff Sparse Vegetation (CEGL006526)$$, but occurs at higher elevations and contains at least some strictly alpine herbs.  Accession Code: urn:lsid:vegbank.org:commConcept:35071-{B9FFE4CC-3E65-431B-8436-A5EF9DA942B0} Plot-observations of this Community Concept: 0
