Rocky Mountain Alpine Nonvascular Bedrock & Scree Alliance | NatureServe Biotics 2019
click to update datacart
Name: Rocky Mountain Alpine Nonvascular Bedrock & Scree Alliance Reference: NatureServe Biotics 2019 Description: Vegetation is characterized by sparse to moderately dense cover (5-40%) of nonvascular species (mostly lichens and mosses) on rocky substrates. Vascular vegetation is absent or sparse, with a few tree, shrub, herbaceous, and moss species growing in rock crevices at some sites with very low coverage (<5%) in openings between rocks. Species vary with site and size of microsite habitats. Nonvascular cover exceeds vascular plant cover. This sparsely vegetated alliance occurs throughout the Rocky Mountains cordillera and alpine areas in high plateaus and ranges in the Colorado Plateau and Great Basin from New Mexico north to central Alberta. Stands occur on rocky scree slopes and boulderfields in the alpine and extend down into the subalpine and montane zones.  Accession Code: urn:lsid:vegbank.org:commConcept:39232-{C0D56C42-0BD3-4ED8-B8D0-6B29149CF0A1} Plot-observations of this Community Concept: 0
