Description: This forested association is a minor type in northwestern Oregon, eastern Idaho, northwestern Wyoming and southwestern Montana. It occurs on gentle to steep slopes, on any aspect in the Rocky Mountains, and limited to valley bottoms and north slopes in northeastern Oregon. Elevation ranges from 1585 to 2900 m (5200-9500 feet). Soils are shallow to deep, derived from sandstone, limestone or quartzite parent materials. The understory is dominated by forbs, and the shrub layer is depauperate. <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> are the overstory dominants, together or individually. <i>Pinus albicaulis, Pinus contorta, Pseudotsuga menziesii</i>, and <i>Larix occidentalis</i> may be present. This type is distinguished from similar associations by the higher cover of <i>Thalictrum occidentale</i>. <i>Arnica cordifolia</i> may also be is present in nearly all stands but has lower abundance on average.
