Name: Abies grandis / Bromus vulgaris Forest
Reference: Western Ecology Working Group of...
Description: This Abies grandis forest occurs in the Ochoco and Blue mountains of northeastern Oregon, and is distinctive because of the lack a shrub layer. Average elevation is 1710 m (5600 feet). North aspects are typical and slope steepness is highly variable. Soils include sandy loam, fine loamy sand, silt loam, and silt over igneous parent material and a mantle of ash. Abies grandis generally dominates the tree layer with cover ranging 7-85% and averaging about 50%. Other trees include Pseudotsuga menziesii and Larix occidentalis with cover of 0-25% and 0-20%, respectively. Shrub cover is insignificant. The herbaceous layer is dominated by graminoid cover of Bromus vulgaris (15-24%) and Carex geyeri (1-6%). Cover of other herbaceous species includes Mitella stauropetala (2-7%), Galium triflorum (1-12%), and Osmorhiza berteroi (= Osmorhiza chilensis) (1-8%). Understory taxa are similar to Abies grandis / Acer glabrum Forest (CEGL000267), except for the absence of Acer glabrum and no shrub layer to speak of.
