Name: Cercocarpus ledifolius / Calamagrostis rubescens Woodland
Reference: Western Ecology Working Group of...
Description: This woodland association is found in eastern Oregon and Idaho. Mean annual precipitation is 56 cm, which falls predominantly as heavy snowfall in the winter. Stands are consistently found on north- or northeast-facing slopes between 1750-1920 m elevation. Slopes are moderate, between 10-40%. Soils are moderately deep varying from gravelly to sandy loams overlying fractured Rhyolitic bedrock. The canopy cover of the woodland/tall shrubland type averages 80%, and is dominated by Cercocarpus ledifolius. The only other tree that occurs in this association is an occasional Prunus emarginata. The shrub layer is sparse. Amelanchier alnifolia and Mahonia repens are ubiquitous while Chrysothamnus viscidiflorus, Ericameria nauseosa (= Chrysothamnus nauseosus) and Eriogonum heracleoides are occasional associates. Calamagrostis rubescens is the dominant grass in lightly to moderately grazed stands. In areas which have received heavy grazing Festuca idahoensis or Achnatherum lemmonii (= Stipa lemmonii) codominate with the Calamagrostis rubescens. Other graminoids include Elymus elymoides (= Sitanion hystrix), Elymus glaucus, Elymus caninus, and Carex rossii. The dominant forb in undisturbed stands is Hieracium cynoglossoides. On disturbed sites Viola nuttallii dominates. Common forbs on all sites include Geum triflorum, Agoseris heterophylla, and Achillea millefolium.
