Name: Tsuga heterophylla / Mahonia nervosa / Achlys triphylla Forest
Reference: Western Ecology Working Group of...
Description: This conifer forest association may occur as young- or old-growth. Stands are found at elevations of 610-1370 m (2000-4500 feet) in Oregon. Aspects are usually northern in the southern Cascades and southwest-facing further north. Slopes average 36%. Soils are typically derived from basaltic or andesitic parent material. The dominant overstory species are <i>Pseudotsuga menziesii</i> (56%) and <i>Tsuga heterophylla</i> (28%). The understory tree layer is dominated by <i>Tsuga heterophylla</i> (6%) with no other tree species present in most stands. The shrub layer is characterized by <i>Mahonia nervosa (= var. nervosa)</i> (31%), <i>Acer circinatum</i> (22%), and <i>Rosa gymnocarpa</i> (2%). Important forbs include <i>Achlys triphylla</i> (12%), <i>Viola sempervirens</i> (4%), <i>Anemone deltoidea</i> (2%), and <i>Tiarella trifoliata</i> (6%).
