Name: Danthonia parryi Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This plant association most commonly occurs in forest openings, in montane meadows or parks in the Colorado Rocky Mountains and in adjacent parts of Wyoming. Stands occur from 2260-3350 m (7400-11,000 feet) elevation. Sites are moderately sloping (10-20%), with south and western aspects. Soils are shallow to moderately deep (>60 cm), usually with less than 20% coarse fragments. Soil texture is sandy to silt loam. The soils are moister than those of adjacent grasslands dominated by <i>Festuca arizonica</i>. The most common adjacent vegetation is <i>Pinus ponderosa</i> forest. At higher elevations there is an ecotone with <i>Pinus contorta</i> forests, and at lower elevations mountain shrub and other dry grassland communities are common. The vegetation is characterized by a moderately dense (60-70% cover) herbaceous layer that is typically dominated by the perennial bunchgrass <i>Danthonia parryi</i>. Other common species include <i>Carex inops ssp. heliophila, Elymus trachycaulus, Festuca arizonica, Festuca idahoensis, Koeleria macrantha, Muhlenbergia montana, Poa fendleriana, Poa pratensis</i>, and <i>Poa secunda</i>. <i>Muhlenbergia montana</i> may be more abundant on drier sites or those impacted by livestock grazing. Forbs are diverse but contribute little cover (usually less than 10%) and include <i>Achillea millefolium var. occidentalis (= Achillea lanulosa), Antennaria rosea, Besseya plantaginea, Eriogonum umbellatum, Heterotheca villosa, Gaillardia aristata, Gentiana</i> spp., <i>Geum macrophyllum, Mertensia lanceolata, Penstemon</i> spp., <i>Potentilla hippiana</i> and <i>Potentilla pulcherrima</i>. The dwarf-shrub <i>Artemisia frigida</i> is often scattered through these stands.  Accession Code: VB.CC.34114.CEGL001795 Plot-observations of this Community Concept: 0
