Name: Abies grandis / Linnaea borealis Forest
Reference: Western Ecology Working Group of...
Description: This forest association is present throughout northeastern Oregon and west-central Idaho and is a minor type in northern Idaho and Montana. The association occupies lower to mid elevations of gentle slopes and benches of various aspects, which are protected from extreme sun and wind. Soils are slightly acidic with only a trace of bare soil and rock. Litter depths can be up to 9 cm (3.54 inches). Mid- to late-seral occurrences are dominated by Abies grandis, with Pinus ponderosa, Larix occidentalis, and Pseudotsuga menziesii being important, or even dominant, seral species in younger stands. Remnant large-diameter stems of these species are often present in the late-successional stands. The low-shrub layer is dominated by Linnaea borealis which often forms extensive mats. Medium-tall shrubs, such as Vaccinium membranaceum, are typically present. Other common shrubs are Rosa gymnocarpa, Lonicera utahensis, and Chimaphila umbellata. In the herbaceous layer, Carex geyeri, Carex concinna, and Carex rossii are all commonly present. The most frequent indicator forbs include Osmorhiza berteroi (= Osmorhiza chilensis), Galium triflorum, Prosartes trachycarpa (= Disporum trachycarpum), and Goodyera oblongifolia.
