Name: Chrysothamnus viscidiflorus / Hesperostipa comata Shrubland Reference: NatureServe Biotics 2019 Description: This association occurs on disturbed ridges and valleys in the northern Colorado Plateau of Colorado and Utah and into the southern Rocky Mountains. The total vegetation cover rarely exceeds 60% and is characterized by an open shrub canopy of <i>Chrysothamnus viscidiflorus</i> with between 5 and 35% cover. The native bunchgrass <i>Hesperostipa comata</i> contributes 10 to 20% cover. Other short shrubs providing sparse cover include <i>Symphoricarpos oreophilus, Artemisia nova</i>, and <i>Tetradymia canescens</i>. The herbaceous layer is diverse in terms of species composition. Associated graminoids include <i>Achnatherum hymenoides, Bouteloua gracilis, Elymus elymoides, Pascopyrum smithii, Poa fendleriana</i>, and <i>Poa secunda</i>. Forbs are diverse but contribute very little cover, including <i>Chenopodium leptophyllum, Crepis acuminata, Cryptantha cinerea var. jamesii, Erigeron engelmannii, Eriogonum umbellatum, Lupinus caudatus, Opuntia fragilis, Packera tridenticulata, Sedum lanceolatum, Senecio spartioides, Linanthus pungens, Heterotheca villosa</i>, and <i>Schoenocrambe linifolia</i>. This association occurs between 1800 and 2440 m (5900-8000 feet) elevation. Slopes range from gentle to moderately steep. Soils have textures ranging from silt loam to sandy loam to loamy sand, and bare soil covers most of the unvegetated ground surface. This community generally occurs in areas that have experienced significant disturbance (such as fire) or on-going natural disturbance such as season-long grazing.  Accession Code: urn:lsid:vegbank.org:commConcept:31701-{56DFACF7-AE47-4DD8-9CA3-6E6D68A6E898} Plot-observations of this Community Concept: 0
