Name: Cercocarpus montanus / Pseudoroegneria spicata Shrubland
Reference: NatureServe Biotics 2019
Description: This association occurs on windswept ridgelines and rocky slopes on foothills and high plateaus in northwestern Colorado, north-central Utah and western Wyoming. It often occurs as inclusions within larger areas of sagebrush. Elevations range from 1511 to 2600 m (4960-8530 feet). Slopes are moderately to very steep and generally are oriented to a north to east aspect, except in Utah, where south-facing stands occur. The substrate is often calcareous, such as limestone or colluvium derived from formations that include limestone. Soils are shallow to deep, rocky sandy or silty loams, and the soil surface is abundantly covered with organic litter. The vegetation is characterized by a shrub canopy dominated by <i>Cercocarpus montanus</i> (20-45% cover) with an herbaceous understory dominated by <i>Pseudoroegneria spicata</i> (5-15% cover). The total vegetative cover is moderate to dense, ranging from 25% to more than 65%. Associated shrubs include <i>Artemisia tridentata (ssp. vaseyana, ssp. wyomingensis), Amelanchier utahensis, Quercus gambelii, Tetradymia canescens, Symphoricarpos oreophilus</i>, and <i>Eriogonum microthecum</i>. The herbaceous stratum has sparse to moderate cover and consists mostly of graminoids. Associated graminoids include <i>Poa fendleriana, Koeleria macrantha, Achnatherum hymenoides, Poa secunda</i>, and <i>Hesperostipa comata</i>. Typical forbs present include <i>Stenotus acaulis</i> and <i>Eriogonum umbellatum</i>.
