Name: Pinus edulis - Juniperus osteosperma / Pseudoroegneria spicata - Cushion Plant Woodland Reference: Western Ecology Working Group of... Description: This association has only been documented from Dinosaur National Monument in northwestern Colorado and adjacent eastern Utah. It occurs on the high windswept ridges and valleys of plateaus and mountains at elevations above 1900 m to as high as 2400 m. Slopes are east- to southwest-facing and gentle to moderately steep. Soils are thin, and texture is variable, depending on the geologic substrate, which is typically limestone or derived from limestone, such as Bishop conglomerate. The soil surface is often covered with gravel and large rocks. The vegetation is characterized by a sparse to moderate tree cover of <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> with an understory of bunchgrasses and cushion plants. The shrub stratum has less than 10% cover and lacks diagnostic species. The herbaceous layer is highly diverse with consistent dominant species. <i>Pseudoroegneria spicata</i> is typically present with low to moderate cover, but in heavily grazed areas, it may be absent. Other grasses that occur consistently include <i>Poa secunda, Poa fendleriana, Achnatherum hymenoides</i>, and <i>Koeleria macrantha</i>. Forbs characterized as "cushion" plants include <i>Stenotus acaulis, Phlox hoodii, Petradoria pumila</i>, and <i>Phlox multiflora</i>. A variety of other forbs also occur in this association, particularly <i>Balsamorhiza sagittata</i>.  Accession Code: VB.CC.31918.CEGL002819 Plot-observations of this Community Concept: 0
