Name: Pseudotsuga macrocarpa - Quercus chrysolepis Forest Alliance
Reference: Western Ecology Working Group of...
Description: This montane forest alliance of central and southern California grows on steep to moderate slopes. Stands are found between 275 and 2400 m of elevation, and grow on slopes of 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. Stands contain Pseudotsuga macrocarpa and Quercus chrysolepis as important canopy species. Other trees present may include Quercus kelloggii, Pinus coulteri, Pinus attenuata, Pinus sabiniana, Pinus monophylla, Umbellularia californica, and Juglans californica. In older stands the canopy tends to be two-tiered, with Quercus chrysolepis forming the subcanopy beneath the conifers. The shrub and herbaceous layers are sparse.
