Name: Juncus parryi - Erigeron ursinus Alpine Snowbed
Reference: NatureServe Biotics 2019
Description: This alpine association has been reported from 2900 to 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. <i>~Festuca idahoensis - (Festuca campestris) / Potentilla diversifolia</i> Grassland (CEGL001623)$$ is 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 <i>Juncus parryi</i> and <i>Festuca idahoensis</i>. <i>Poa glauca</i> is consistently present. Dominance of the forb component is shared among <i>Erigeron ursinus, Erigeron peregrinus, Erigeron simplex, Antennaria umbrinella</i>, and <i>Lewisia pygmaea</i>. Cover of mosses and lichens is typically low (2%).
