This minor forest association occurs in scattered locations in the lower subalpine zone of the northern Rocky Mountains. Stands are typically found on steep mountain slopes on northern aspects, at elevations ranging from 1525-2290 m (5000-7500 feet). Sites are cool and moist. Substrates are typically loams or less commonly silt loams or silts. Litter dominates ground cover often 6 cm deep with low cover of rock and bare ground. The vegetation is characterized by a tree canopy codominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> with tall shrub <i>Alnus viridis ssp. sinuata</i> dominating the understory. The evergreen needle-leaved tree canopy is moderately dense (60-90% cover) and is typically codominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> with lesser amounts of <i>Pinus contorta, Pseudotsuga menziesii, Pinus albicaulis</i>, and <i>Larix occidentalis</i> (west of the Continental Divide). The tall-shrub layer is composed of dense patches and is dominated by <i>Alnus viridis ssp. sinuata</i> with scattered <i>Ribes lacustre</i>. <i>Vaccinium membranaceum, Vaccinium myrtillus</i>, and/or <i>Vaccinium scoparium</i> often form a dwarf-shrub layer. The herbaceous layer is typically sparse and composed of diverse forbs such as <i>Arnica cordifolia, Arnica latifolia, Osmorhiza berteroi (= Osmorhiza chilensis), Orthilia secunda (= Pyrola secunda), Thalictrum occidentale</i>, and <i>Xerophyllum tenax</i>. |

Shrublands on moderately saline, sandy soils in the Trans-Pecos and South Texas Plains. Composition varies with geographic location with <i>Lycium berlandieri, Ziziphus obtusifolia, Opuntia</i> spp., and <i>Yucca elata</i> are common shrub associates. In more saline areas, shrubs are more sparse and grasses and forbs are more common, including <i>Sporobolus airoides, Distichlis spicata</i>, and <i>Sesuvium verrucosum</i>. These shrublands may grade into grasslands dominated by <i>Sporobolus airoides</i> or <i>Pleuraphis mutica (= Hilaria mutica)</i> or be surrounded by a matrix of desert shrubland. |

This cool and moist forest association is known from northern Nevada, eastern Idaho, southwestern and central Montana, and western and north-central Wyoming. This is a cool and moist forest on gentle to moderate terrain, bench-like uplands, often on north-facing slopes but can occur on any aspect. It occurs between 2105 and 2900 m (6900-9500 feet) in elevation. The overstory canopy is thick with mostly <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> in the overstory canopy. <i>Pinus contorta</i> and <i>Pseudotsuga menziesii</i> are often present. Shrub cover is low and scattered, with the exception of <i>Shepherdia canadensis</i>, which can have as much as 10% cover, and was indicated as present in a least some plots by all authors. Other shrubs that may be present include <i>Ribes montigenum, Paxistima myrsinites</i>, and <i>Rosa</i> spp. The herbaceous layer is not abundant; <i>Arnica cordifolia</i> is the most consistently present forb with about 10-15% cover on average. A wide variety of other herbaceous species may be present, but none with any consistency. <i>Arnica latifolia</i> can be difficult to distinguish from <i>Arnica cordifolia</i>. The leaves on flowering stems of <i>Arnica latifolia</i> are largest toward the middle and are short-petioled to sessile, whereas those of <i>Arnica cordifolia</i> are largest near the base and are distinctly petiolate. <i>Arnica latifolia</i> is restricted to relatively moist sites; <i>Arnica cordifolia</i> occurs on many dry forest sites. |
