Name: Abies grandis / Clintonia uniflora Forest
Reference: NatureServe Biotics 2019
Description: This association is found in northern Idaho, western Montana, eastern Washington, and northeastern Oregon at between 610 and 1860 m (2000-6100 feet) elevation. It represents a moist extreme of <i>Abies grandis</i> forests and usually occupies moist, well-drained slopes, benches, and stream terraces that are protected from extreme sun and wind on all aspects. This type is most often found on concave to undulating surface relief, receiving additional moisture and nutrients from the surrounding, more elevated landscape. Parent materials are usually basalt or granitics. Stands in this association are predominantly uneven-aged. <i>Abies grandis</i> is the indicated climax tree species and dominates both the overstory and understory in old-growth stands. <i>Pseudotsuga menziesii</i> and <i>Picea engelmannii</i> act as secondary seral dominants, with spruce in virtually all age classes in old-growth stands. <i>Pinus ponderosa, Larix occidentalis</i>, and <i>Pinus contorta</i> are the primary invaders of severely disturbed sites. In the shrub layer, <i>Vaccinium membranaceum</i> or <i>Acer glabrum</i> dominate the undergrowth. <i>Vaccinium membranaceum</i> (twice as abundant in early-seral stands), <i>Rosa gymnocarpa, Lonicera utahensis</i>, and <i>Linnaea borealis</i> are often abundant in this type. <i>Clintonia uniflora</i> accompanies a mixture of moist-site forbs in the herbaceous layer. Some moist-site indicators commonly present are <i>Bromus vulgaris, Adenocaulon bicolor, Maianthemum stellatum, Coptis occidentalis</i>, and <i>Prosartes trachycarpa</i>.
