Name: Pseudoroegneria spicata Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association typically occurs at elevations between 7200-9300 feet. It can occur on any aspect but is most likely found on south-facing, nearly flat to gently sloping rock outcrops, mesas, plateaus and ridgetops. Although this association can occur on steeper surfaces, slopes generally do not exceed 15%. Soils are rocky with an average pH of 7.9. The predominant parent materials are sandstone and marlstone of the Uinta and Green River formations. The vegetation cover in this association is very thinly distributed with bare ground often exceeding 40%. This association consists of a very sparse collection of graminoids and low-growing forbs. Artemisia frigida can occur in small amounts, but for the most part a shrub layer is nonexistent. Pseudoroegneria spicata occurs with 5-7% cover and Koeleria macrantha is repeatedly present in low abundance. The low-growing forbs that are consistently present with 1-5% cover are Arenaria hookeri, Astragalus spatulatus, Draba oligosperma, Tetraneuris acaulis (= Hymenoxys acaulis), Lesquerella alpina, Paronychia sessiliflora, Phlox hoodii, Townsendia incana, and Eriogonum lonchophyllum. There are no clear dominants in this list and the percent of each species present will vary from site to site. A diverse and abundant forb layer probably indicates a degraded occurrence (R. Rondeau pers. comm. 1998).  Accession Code: VB.CC.25916.PSEUDOROEGNERIA Plot-observations of this Community Concept: 0
