Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Oregon White Oak / Common Snowberry Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a deciduous woodland association with a deciduous shrub undergrowth. It is generally associated with streams near lower timberline in the eastern Cascades in south-central Washington. These riparian sites are generally found between 490 and 1070 m (1600-3500 feet) elevation. The existing vegetation is characterized by an open Quercus garryana layer occasionally with scattered taller Pinus ponderosa or Pseudotsuga menziesii trees. Symphoricarpos albus is the most common shrub often with Quercus garryana in the shrub layer. The herbaceous layer is poorly represented by a mix of graminoids and forbs.

Classification Comments: British Columbia was removed from this association based on recommendation from D. Meidinger (pers. comm. 2016): "There is no ponderosa pine in BC in the range of Garry oak (listed in the alliance for CEGL000553). There is Symphoricarpos albus associated with Quercus garryana, but I think this is captured by CEGL003358 rather than also having CEGL000553."
