Name: Pinus lambertiana - Pinus ponderosa - Pseudotsuga menziesii / Festuca californica Forest
Reference: Western Ecology Working Group of...
Description: Average elevation for this association is 930 m (3050 feet); aspect is variable, though generally not north. Slopes average 32%, with a range of 15-65%. Slope position ranges from mid-slope to ridgetop. Parent materials are composed of andesite, basalt, mixed ultramafics, schist and diorite. Surface texture is loam, with 20-40% gravel and cobbles. Subsurface texture is loam with 60% cobbles. This mixed conifer association is dominated by <i>Pinus ponderosa</i> and <i>Pseudotsuga menziesii</i>, both with low cover, averaging 16% and 17%, respectively. <i>Pinus lambertiana</i> is a constant canopy associate found at low cover. The regeneration layer is dominated by <i>Pinus ponderosa</i>, with <i>Pseudotsuga menziesii</i> frequently occurring. <i>Pinus lambertiana, Calocedrus decurrens, Abies concolor</i>, and <i>Quercus chrysolepis</i> also commonly occur in the regeneration layer. <i>Arbutus menziesii, Quercus garryana, Chrysolepis chrysophylla</i>, and <i>Acer macrophyllum</i> are rarely present. <i>Toxicodendron diversilobum</i> is the only commonly occurring shrub. <i>Madia madioides</i> and <i>Iris chrysophylla</i> commonly occur, while <i>Festuca californica</i> and <i>Fragaria vesca</i> are occasional. Moss cover averages 4%.
