Name: Juncus drummondii - Antennaria lanata Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This alpine wetland community has been described from only the southern Madison Range in southwestern Montana (2930-3050 m elevation), where it occurs regularly as small patches (much less than one acre in extent). Stands are common in alpine valley depressions, swales and cirque basins in association with late-persisting snowbeds. This snowbed community occurs on gentle terrain (4-22% slope) with various aspects, often as a mosaic with other snowbed communities. Soils are typically shallow, well-drained and have sandy clay texture with 13% coarse fragments derived from gneiss and granite parent materials. Gravel and bare ground cover 50% of the soil surface. The vegetation layer is a mixture of graminoids (30% mean cover) and forbs (37% mean cover) with graminoids generally dominant. The major graminoids are Juncus drummondii, Poa fendleriana, and Carex paysonis. The most common forb species are Antennaria lanata, Sibbaldia procumbens, and Erigeron peregrinus. The dwarf-shrub Vaccinium scoparium and Carex paysonis were important (10% cover each) in one of the three stands sampled. Mosses and lichens had relatively low cover. Diagnostic of this relatively sparse alpine association is the codominance of Juncus drummondii and Antennaria lanata.  Accession Code: VB.CC.21416.JUNCUSDRUMMONDI Plot-observations of this Community Concept: 0
