Name: Tsuga mertensiana - Abies amabilis / Xerophyllum tenax Forest
Reference: Western Ecology Working Group of...
Description: 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.
