Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Shasta Red Fir / Pipsissewa Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: These forests are common in the southern Cascades and less extensive in the Klamath-Siskiyou region. The association is typically a closed-canopy forest with gaps at boulders. Elevations average 1650 m (5420 feet). Slopes range between 3 and 50% and are usually west or northwest-facing. Soils are loamy sands with parent material varies from andesite and basalt to diorite and granite. The tree canopy is codominated by Abies lowiana and Abies magnifica var. shastensis. The understory is extremely sparse and includes Rosa gymnocarpa and Chimaphila umbellata.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Atzet et al. (1996) refer to this association as Abies concolor - Abies magnifica var. shastensis / Chimaphila umbellata - Anemone deltoidea. Hopkins (1979b) describes a similar type, Shasta red fir- white fir / chinquapin - prince''s pine / long-stolon sedge (Abies x shastensis - Abies concolor / Chimaphila umbellata / Carex pensylvanica).
