Description:
This coniferous forest alliance is dominated by <i>Chamaecyparis lawsoniana</i>, usually codominated with other tree species such as <i>Abies lowiana, Abies magnifica, Callitropsis nootkatensis, Picea breweriana, Picea sitchensis, Pseudotsuga menziesii, Taxus brevifolia</i>, and <i>Tsuga heterophylla</i>. Other trees that may be present are broad-leaved tree species such as <i>Acer macrophyllum, Alnus rubra, Chrysolepis chrysophylla</i>, and <i>Notholithocarpus densiflorus</i>. The tall-shrub stratum can be dominated by <i>Acer circinatum, Gaultheria shallon, Rhododendron macrophyllum</i>, or <i>Vaccinium parvifolium</i>. Shorter shrubs may include <i>Chimaphila umbellata, Leucothoe davisiae, Mahonia nervosa, Paxistima myrsinites, Rosa gymnocarpa, Rubus ursinus</i>, or <i>Vaccinium membranaceum</i>. Herbaceous layers commonly have shade-tolerant species such as <i>Clintonia uniflora, Goodyera oblongifolia, Linnaea borealis, Oxalis oregana</i>, and <i>Polystichum munitum</i>. This alliance has a restricted range in the Klamath-Siskiyou mountain region of northern California and southern Oregon, but shows wide ecological amplitude within that range.
