Name: Pseudotsuga macrocarpa - Quercus chrysolepis Forest Alliance
Reference: NatureServe Biotics 2019
Description: This is an alliance of forests with <i>Pseudotsuga macrocarpa</i> as the sole dominant or codominant with other trees, including <i>Quercus chrysolepis</i>. Other trees present may include <i>Quercus agrifolia, Quercus kelloggii, Pinus coulteri, Pinus attenuata, Pinus sabiniana, Pinus monophylla, Umbellularia californica</i>, and <i>Juglans californica</i>. The shrub and herbaceous layers are sparse. This alliance is restricted to southern California Coast, Peninsular and Transverse ranges (and just barely into the central Coast Ranges). Stands occur at montane elevations, between 275 and 2400 m, on steep to moderate slopes at all aspects. Annual precipitation varies with elevation, and ranges from 70-100 cm, with a distinct summer dry season. Precipitation is episodic, and droughts of several years duration are not uncommon. Soils that support this alliance are skeletal, rocky, and well-drained.
