This association is described based on data collected on 30 plots located in northern Idaho in the Clearwater River watershed. The association occurs on moist, low to moderately sloped sites in mid, lower, to toeslope positions at moderately low elevation (generally <915 m [3000 feet]) between the St. Joe and Selway rivers, Idaho. Stands are characterized by a lush understory dominated by <i>Adiantum pedatum</i> and <i>Polystichum munitum</i>. <i>Adenocaulon bicolor, Asarum caudatum, Clintonia uniflora</i>, and <i>Coptis occidentalis</i> and many other species form a rich herbaceous layer. Wet-site species such as <i>Trautvetteria caroliniensis</i> and <i>Senecio triangularis</i> may occur with low abundance but are characteristically less abundant than on adjacent <i>Thuja plicata / Athyrium filix-femina</i> sites. <i>Thuja plicata</i> is typically dominant in late-seral stands. <i>Tsuga heterophylla</i> is present in some stands. <i>Abies grandis</i> is often the dominant tree in early and mid-seral stands. |

This broadly defined type represents vegetation dominated by scrubby forms of <i>Salix nigra</i> across the southeastern and northeastern United States, and possibly into Canada. Stature and closure may vary depending on disturbance. Additional types may be developed as more information becomes available. |

Endemic to part of the upper elevations of the eastern Cascades of Washington, this association is restricted to a few sections of Bailey's Eastern Cascades (M242C) between Snoqualmie Pass and Mount Adams. This is a high-elevation, closed-canopy forest association composed of trees that are rarely over 200 years old. These are some of the driest sites supporting <i>Tsuga mertensiana</i> in the Cascades. Found in the mid elevational range of other <i>Tsuga mertensiana</i> communities, these sites are gravelly, usually on ridges and upper slopes and associated with heavy snow accumulation. <i>Tsuga mertensiana</i> is always present and usually the most abundant tree in the upper canopy. <i>Larix occidentalis, Pinus contorta var. latifolia, Abies lasiocarpa</i>, or <i>Abies amabilis</i> can be abundant. <i>Tsuga mertensiana, Abies lasiocarpa</i>, and <i>Abies amabilis</i> are the most common tree species in lower canopy. The evergreen perennial forb <i>Xerophyllum tenax</i> is the most common and abundant species in the undergrowth. <i>Vaccinium myrtillus</i> and <i>Paxistima myrsinites</i> are common shrub associates. Few forbs occur in this community. |
