Name: Tsuga heterophylla / Chrysolepis chrysophylla Forest
Reference: Western Ecology Working Group of...
Description: This conifer forest association is restricted to the Klamath Mountains and southern Cascade Mountains in Oregon. Stands are most common near ridgetops at elevations of 460-790 m (1508-2591 feet). Sites are generally steep slopes with a south or southwest aspect. Most soils are of pyroclastic parent material, shallow, stony, and loamy. A moderately open canopy and a dense shrub understory typify these conifer forests that vary between young- and old-growth. The tree canopy is composed of Tsuga heterophylla and Pseudotsuga menziesii with 7% and 36% cover, respectively. The shrub layer is dominated by Rhododendron macrophyllum, Chrysolepis chrysophylla (= Castanopsis chrysophylla), Acer circinatum, Gaultheria shallon, and Mahonia nervosa (= var. nervosa) with 40%, 23%, 18%, 40%, and 10% cover, respectively. Linnaea borealis (5%) and Xerophyllum tenax (10%) are the only herbs to average greater than 1% cover. This is the only Tsuga heterophylla association in the Cascades to support Xerophyllum tenax with any notable cover.
