Name: Pseudotsuga menziesii / Mahonia aquifolium Forest
Reference: Western Ecology Working Group of...
Description: This forest association of the central and eastern Siskiyou mountains grows between 540-1525 m of elevation on southern aspects. Stands occupy all slope positions and topography. Sites are very warm and dry. Parent materials are metavolcanics and metasediments. Pseudotsuga menziesii dominates the overstory tree canopy, with a much smaller percentage of Pinus ponderosa. The tree understory contains Pseudotsuga menziesii, Arbutus menziesii and/or Quercus kelloggii. Mahonia aquifolium (= Mahonia piperiana) and Toxicodendron diversilobum are the most constant shrub species. Ceanothus integerrimus invades sites that have been disturbed or burned.
