Common (Translated Scientific) Name: Subalpine Fir - Mountain Hemlock / Grouse Whortleberry Woodland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This subalpine fir - mountain hemlock forest of Washington, Oregon and possibly California has a canopy that is usually codominated by Abies lasiocarpa and Tsuga mertensiana. Pinus contorta is occasionally prominent to codominant. The dwarf-shrub layer is well-developed. Vaccinium scoparium is prominent to dominant and diagnostic. Vaccinium deliciosum is occasionally prominent. Taller shrubs can be absent or moderate in cover. Vaccinium membranaceum is often prominent. One or more of the following species may be prominent in the variable herb layer: Xerophyllum tenax, Rubus lasiococcus, Arnica latifolia, and Luzula glabrata var. hitchcockii. This woodland or open forest association occurs at high elevations on gentle slopes with a variety of aspects. Sites usually have rocky, well-drained soils. This association may occur on eastern or northern slopes of Mount Rainier or in the eastern North Cascades. It is known to occur further east and south in the Cascades.
