Name: Tsuga heterophylla / Chrysolepis chrysophylla Forest
Reference: NatureServe Biotics 2019
Description: This conifer forest association is restricted to the Klamath Mountains and southern Cascade Range in Oregon. 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 <i>Tsuga heterophylla</i> and <i>Pseudotsuga menziesii</i>. The shrub layer is dominated by <i>Rhododendron macrophyllum, Chrysolepis chrysophylla, Acer circinatum, Gaultheria shallon</i>, and <i>Mahonia nervosa</i>. <i>Linnaea borealis</i> and <i>Xerophyllum tenax</i> are the only herbs to average greater than 1% cover. This is the only <i>Tsuga heterophylla</i> association in the Cascades to support <i>Xerophyllum tenax</i> with any notable cover. 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.
