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 Tsuga mertensiana in the Cascades. Found in the mid elevational range of other Tsuga mertensiana communities, these sites are gravelly, usually on ridges and upper slopes and associated with heavy snow accumulation. Tsuga mertensiana is always present and usually the most abundant tree in the upper canopy. Larix occidentalis, Pinus contorta var. latifolia, Abies lasiocarpa, or Abies amabilis can be abundant. Tsuga mertensiana, Abies lasiocarpa, and Abies amabilis are the most common tree species in lower canopy. The evergreen perennial forb Xerophyllum tenax is the most common and abundant species in the undergrowth. Vaccinium myrtillus and Paxistima myrsinites are common shrub associates. Few forbs occur in this community.
