Name: Abies grandis / Bromus vulgaris Forest
Reference: Western Ecology Working Group of...
Description: This <i>Abies grandis</i> 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. <i>Abies grandis</i> generally dominates the tree layer with cover ranging 7-85% and averaging about 50%. Other trees include <i>Pseudotsuga menziesii</i> and <i>Larix occidentalis</i> with cover of 0-25% and 0-20%, respectively. Shrub cover is insignificant. The herbaceous layer is dominated by graminoid cover of <i>Bromus vulgaris</i> (15-24%) and <i>Carex geyeri</i> (1-6%). Cover of other herbaceous species includes <i>Mitella stauropetala</i> (2-7%), <i>Galium triflorum</i> (1-12%), and <i>Osmorhiza berteroi (= Osmorhiza chilensis)</i> (1-8%). Understory taxa are similar to ~<i>Abies grandis / Acer glabrum</i> Forest (CEGL000267)$$, except for the absence of <i>Acer glabrum</i> and no shrub layer to speak of.
