Name: Festuca thurberi Subalpine Grassland Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association occurs in the subalpine areas of Colorado and New Mexico from 2740-3810 m (9180-12,500 feet) elevation. In New Mexico it is restricted to warm, steep, and southeast-facing slopes and ridgetops. In Colorado it has been documented on Gunnison National Forest on steep, fine scree slopes and at Rocky Mountain National Park in mountain valley meadows on gentle to moderately steep slopes. Snow accumulation is apparently very great, but melting and runoff occur rapidly. This grassland is dominated by <i>Festuca thurberi</i>, although other graminoids may be present, such as <i>Danthonia parryi, Deschampsia caespitosa, Festuca brachyphylla, Elymus</i> spp., <i>Trisetum spicatum</i>, and <i>Carex siccata (= Carex foenea)</i>. If present, <i>Festuca idahoensis</i> and <i>Festuca arizonica</i> have low cover and are not codominant. Forbs may include <i>Achillea millefolium, Antennaria anaphaloides, Geum rossii, Oreochrysum parryi, Oreoxis alpina, Phacelia sericea, Senecio atratus, Solidago multiradiata var. scopulorum</i>, and <i>Trifolium dasyphyllum</i>. Scattered <i>Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)</i> may be present to abundant. <i>Lathyrus lanszwertii var. leucanthus</i> and <i>Vicia americana</i> are not present. Although this association is similar to <i>Festuca thurberi</i> grasslands of the montane zone, it differs in that it contains many taxa with an optimum in the alpine zone.  Accession Code: VB.CC.34152.CEGL001631 Plot-observations of this Community Concept: 0
