Name: Juncus drummondii - Antennaria lanata Alpine Snowbed Reference: NatureServe Biotics 2019 Description: This upper subalpine to alpine wetland community has been described from the southern Madison Range in southwestern Montana and the Grand Teton Mountains of northwestern Wyoming. Elevations range from 2743-3050 m. The community occurs regularly as small patches (much less than one acre in extent) in valley depressions, swales and cirque basins in association with late-persisting snowbeds. Slopes are gentle to moderate (3-41% slope) with various aspects, and the association often occurs as a mosaic with other snowbed communities. Soils are typically shallow, well-drained and have a sandy clay texture derived from gneiss and granite parent materials. Gravel and bare ground cover up to 50% of the soil surface. Diagnostic of this relatively sparse alpine association is the codominance of <i>Juncus drummondii</i> and <i>Antennaria lanata</i>. The major graminoids are <i>Juncus drummondii, Poa fendleriana</i>, and <i>Carex paysonis</i>. The most common forb species are <i>Antennaria lanata, Sibbaldia procumbens</i>, and <i>Erigeron peregrinus</i>. The dwarf-shrub <i>Vaccinium scoparium</i> and <i>Carex paysonis</i> are important (10% cover each), and mosses and lichens have relatively low cover. Scattered shrubs and trees may also be present.  Accession Code: urn:lsid:vegbank.org:commConcept:30813-{18BDE48D-1940-4E30-8A43-086A92FF6C3A} Plot-observations of this Community Concept: 0
