CEGL000036 Abies magnifica var. shastensis / Polemonium pulcherrimum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Shasta Red Fir / Beautiful Jacob''s-ladder Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Large conifer trees on cool sites are typical for the association. This community occurs in the Klamath-Siskiyou and southern Cascades regions of Oregon and may also occur in northwestern California. Site can be found on all slopes less than 60% on northern aspects at elevations of 1770-2040 m (5800-6680 feet). Soils are not well documented, but are probably moderately deep (1 m) with texture of sandy loam or loamy sand. The tree canopy is dominated by Abies magnifica var. shastensis. Abies lowiana is occasionally present. Important understory components are Polemonium pulcherrimum and Moehringia macrophylla.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Atzet et al. (1996) re-classified this association as Abies x shastensis / Osmorhiza chilensis. However, their new type was not restricted to northern aspects.
