Name: Phyllodoce empetriformis / Antennaria lanata Dwarf-shrubland Reference: Western Ecology Working Group of... Description: This association is an alpine snowbed type documented to occur on crystalline substrates in the mountain ranges of southwestern and northwestern Montana. In southwestern Montana it is associated with the ranges (Anaconda-Pintlar, Madison, East Pioneer) receiving greater precipitation than other ranges of this region. In southwestern Montana this vegetation is locally common as small patches on depressions and protected slopes of gentle to moderate inclination occurring at 2800-3080 m (9200-10,100 feet) elevation. Based on reconnaissance information for northwestern Montana and the Bitterroot Range, this association occurs within the upper subalpine zone, as well as alpine habitats. Sites are snow covered in winter, and meltoff probably occurs relatively late in the growing season, though not so late as in the ~<i>Carex nigricans</i> Herbaceous Vegetation (CEGL001816)$$. Dwarf-shrubs provide the dominant aspect with a mean cover of 55%. <i>Phyllodoce empetriformis</i> is diagnostic and generally dominant with the other dwarf-shrubs, <i>Vaccinium scoparium, Phyllodoce glanduliflora</i>, and <i>Cassiope mertensiana</i>, being common and occasionally codominant. Mean graminoid canopy cover is low (20%) and characterized by high constancy for <i>Carex paysonis, Juncus drummondii</i>, and <i>Poa secunda (= Poa sandbergii)</i>. Forbs averaged 35% cover; <i>Antennaria lanata, Polygonum bistortoides</i>, and <i>Sibbaldia procumbens</i> are consistently present, though only <i>Antennaria lanata</i> occurs with greater than 5% cover. This association often occurs in a matrix with other snowbed types (e.g., ~<i>Juncus drummondii - Antennaria lanata</i> Herbaceous Vegetation (CEGL001904)$$, ~<i>Carex nigricans</i> Herbaceous Vegetation (CEGL001816)$$, ~<i>Cassiope mertensiana / Carex paysonis</i> Dwarf-shrubland (CEGL001396)$$) and moist turf types (e.g., ~<i>Carex scirpoidea - Geum rossii</i> Herbaceous Vegetation (CEGL001866)$$).  Accession Code: VB.CC.33270.CEGL001405 Plot-observations of this Community Concept: 0
