CEGL000051 Abies lowiana - Picea breweriana / Gaultheria ovatifolia / Orthilia secunda Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Brewer Spruce / Western Teaberry / Sidebells Wintergreen Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is a rare, mixed-conifer community located on cool, wet sites and codominated by the regional endemic Picea breweriana. This association is restricted to the Klamath-Siskiyou region at elevations of 1220-1525 m (4000-5000 feet). Aspects are variable with slopes ranging from 16-47%. Sites are characterized by concave topography on schist and mixed metamorphic parent material. Abies lowiana, Picea breweriana, and Pinus lambertiana codominate the tree canopy. Gaultheria ovatifolia, Chimaphila umbellata, and Vaccinium parvifolium are important understory components.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Atzet and Wheeler (1984) classified this association as Abies concolor - Picea breweriana / Gaultheria ovatifolia. This association was not recognized in Atzet et al. (1996) reclassification of southwestern Oregon, and so an analysis of the data for all Picea breweriana types is essential. Oregon Natural Heritage Program believes this is a good type.

Physiognomy and Structure: No Data Available
Floristics: Abies lowiana (= Abies concolor var. lowiana), Picea breweriana, and Pinus lambertiana codominate the tree canopy with 17%, 17%, and 11% cover, respectively. Gaultheria ovatifolia, Chimaphila umbellata, and Vaccinium parvifolium are important understory components, each supporting about 8% cover.
