Name: Abies grandis / Acer glabrum Forest
Reference: Western Ecology Working Group of...
Description: These conifer forests are native to the Blue Mountains and Wallowa mountains of northeastern Oregon, southeastern Washington and Idaho's Payette National Forest. This forest association is typified by a rich shrub layer, and occurs both on mid-slopes and riparian corridors at elevations of 1000-1950 m (3300-6400 feet). Sites occur on all aspects and a wide variety of slopes. Soils tend to be silt loam and sand over residuum, colluvium, and alluvium of igneous rock with an ash mantle. The tree canopy is dominated by Abies grandis averaging 42% cover. Occasional codominants are Picea engelmannii (18% cover), Pseudotsuga menziesii (17% cover), and Larix occidentalis (10% cover). The shrub cover is composed of Acer glabrum (10%), Vaccinium membranaceum (7%), and Rosa gymnocarpa (4%). Cover of common herbaceous species includes Arnica cordifolia (6%), Galium triflorum (3%), Osmorhiza berteroi (= Osmorhiza chilensis) (3%), and Thalictrum occidentale (4%). Bromus vulgaris (2%) is the only grass reported. Codominating tree species tend to be less common in the Wallowa and Seven Devils mountains.
