Name: Pseudotsuga menziesii / Muhlenbergia montana Forest Reference: Western Ecology Working Group of... Description: This forested plant association occurs on mountains and plateaus in Trans-Pecos Texas, New Mexico, Arizona, and possibly Colorado. Sites are variable and include rocky ridgetops, gentle to steep slopes, streamsides and cinder cones. Elevation ranges from 2650-2970 m (8700-9750 feet) on steep south- and west-facing slopes, and down to 2245 m (7500 feet) on cool, northerly slopes. Substrates are generally dry, shallow, well-drained, gravelly or cobbly, coarse-textured soils. Lower elevation soils may be deep sand or cinder. The vegetation is characterized by a moderately dense, evergreen tree canopy dominated or codominated by Pseudotsuga menziesii with a Muhlenbergia montana-dominated graminoid layer. Other tree species may include large Pinus ponderosa (often codominant) and scattered Pinus strobiformis, Pinus flexilis, Pinus edulis, or Juniperus spp. (especially on drier sites). Abies concolor is not present or accidental. Quercus gambelii may be present in the subcanopy (tree form) or tall-shrub layer, but with less than 5% cover. Shrub cover is typically sparse (<10% cover) and consists of scattered Ceanothus fendleri, Cercocarpus montanus, Holodiscus dumosus, Mahonia repens, Quercus grisea, or Ribes cereum. The herbaceous layer is dominated by graminoids and is moderately dense and diverse. Muhlenbergia montana is the most consistent graminoid species and typically dominates. Forb cover is sparse.  Accession Code: VB.CC.27298.PSEUDOTSUGAMENZ Plot-observations of this Community Concept: 0
