Name: Juncus parryi - Erigeron ursinus Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This alpine association has been reported from 2900-2990 m (9500-9800 feet) elevation only in southwestern Montana, specifically within the Gravelly Range. This is a small-patch type locally common at the base of gentle to steep slopes with warm aspects (generally southerly to westerly). These are snow-accumulation sites that experience early meltoff. Sites are open, having in excess of 50% exposed substrate. Festuca idahoensis - Potentilla diversifolia Herbaceous Vegetation (CEGL001623) was most commonly the adjacent plant community. These sites lack a shrub component, and the graminoid component averages 35% cover with the forb cover more scarce at 20%. The dominant graminoids are the diagnostic Juncus parryi and Festuca idahoensis. Poa glauca is consistently present. Dominance of the forb component is shared among Erigeron ursinus, Erigeron peregrinus, Erigeron simplex, Antennaria umbrinella, and Lewisia pygmaea. Juncus parryi - Erigeron ursinus Herbaceous Vegetation (CEGL001906) is similar in physiognomy and habitat to Juncus drummondii - Antennaria lanata Herbaceous Vegetation (CEGL001904) and even occurs in the same landscapes, but the former is associated with terrain supporting alpine grassland, and the latter is embedded in terrain supporting turf communities.  Accession Code: VB.CC.20444.JUNCUSPARRYIERI Plot-observations of this Community Concept: 0
