CEGL005813 Pseudotsuga menziesii - Abies lowiana - Calocedrus decurrens Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Sierra White Fir - Incense-cedar Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs throughout the northern Sierra Nevada and southern Cascades of California at least as far south as Yosemite Valley. Stands of this forest are found at low elevations (640-1460 m [2100-4800 feet]) at cool, moist sites with humid air. These sites tend to occur on north- or northeast-facing, gentle to moderately steep (12-80%), lower or mid slopes. Sites are often adjacent to perennial streams generally occupying small areas. Soils are moderately deep to deep in metamorphic or volcanic substrates. Coarse fragments tend to be higher in this association. Fire is infrequent, with low to medium intensities and variable spread. Stands of this forest form a dense, multi-layered overstory of Pseudotsuga menziesii, Abies lowiana, and Calocedrus decurrens. Corylus cornuta is in the shrub layer, and dense patches of both or either Adenocaulon bicolor or Trichostema lanceolatum are in the herb layer. Pseudotsuga menziesii dominates and occasionally codominates with Abies lowiana. Calocedrus decurrens, Pinus lambertiana, and occasionally Pinus ponderosa are minor associates. Infrequently, Taxus brevifolia and Torreya californica are present. Pseudotsuga menziesii dominate the regeneration, but Abies lowiana and Calocedrus decurrens can also be high or dominant. Quercus kelloggii, Pinus lambertiana, and Cornus nuttallii are common in low amounts. Quercus chrysolepis occurs in the overstory and midstory on sites with limiting soil conditions, either shallow and stony sites with limited rootability or very high coarse fragments. Corylus cornuta forms a tall-shrub layer of variable cover. The herb layer is well-developed with dense patches dominated by Adenocaulon bicolor and Trichostema lanceolatum.

Floristics: Stands of this forest form a dense, multi-layered overstory of Pseudotsuga menziesii, Abies lowiana (= Abies concolor var. lowiana), and Calocedrus decurrens. Corylus cornuta is in the shrub layer, and dense patches of both or either Adenocaulon bicolor or Trichostema lanceolatum are in the herb layer. Pseudotsuga menziesii dominates and occasionally codominates with Abies lowiana. Calocedrus decurrens, Pinus lambertiana, and occasionally Pinus ponderosa are minor associates.

Fire is infrequent, with low to medium intensities and variable spread (Fites 1994).
Geographic Range: This association occurs throughout the northern Sierra Nevada and southern Cascades (Fites 1994) at least as far south as Yosemite Valley. Don Potter (pers. comm. 2002) has sampled this association near Carlon. The southern range limit is probably Big Creek near Huntington Lake, Fresno County.
