click to update datacart
Name: Rhizocarpon geographicum Sparsely Vegetated Alpine Nonvascular Alliance Reference: NatureServe Biotics 2019 Description: The vegetation is characterized by an assortment of evergreen shrubs, bryophytes, lichens, and/or dwarf woody plants. Shrub and herbaceous covers are both sparse, and species composition is patchy, variable and typically restricted to cracks and crevices of rocks where soil accumulates. The most common dominant shrubs include <i>Juniperus communis</i> and <i>Phyllodoce glanduliflora</i> and shrub-form <i>Abies lasiocarpa</i>. The most common herbaceous species include <i>Antennaria alpina, Carex spectabilis, Juncus drummondii, Luetkea pectinata, Penstemon davidsonii, Phacelia sericea, Saxifraga bronchialis, Sibbaldia procumbens</i>, and <i>Silene acaulis</i>. The most common nonvascular dominants include the moss <i>Polytrichum piliferum</i> and lichens <i>Rhizocarpon geographicum</i> and <i>Umbilicaria proboscidea</i>. Associations of this alliance occur in coastal mountain ranges of British Columbia. Sites include moderately dry, rock walls, rock bluffs, and ridges. These habitats are very exposed and subjected to extreme wind-scour. Soils are thin, acidic, and consist mostly of accumulations of grit and sand in cracks between rocks.  Accession Code: urn:lsid:vegbank.org:commConcept:39297-{17777729-2F44-4E06-9FBD-129886842F7A} Plot-observations of this Community Concept: 0
