Name: Quercus garryana / Symphoricarpos albus / Carex inops Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs in the Puget Lowland of western Washington and the Georgia Basin of southwestern British Columbia at low elevations. Sites occupied are relatively dry and range from deep, gravelly glacial outwash plains to soils that are shallow to bedrock. In pre-European settlement times, this association was probably strongly influenced by anthropogenic fires, and sites occupied today may have had a very different species composition in the past. Fires helped maintain the dominance of oak over conifers, but also probably kept the shrub layer from dominating the understory on the sites where the type now exists. This deciduous broad-leaved woodland or forest is dominated by Quercus garryana and frequently has significant amounts of the evergreen conifer Pseudotsuga menziesii (mean 8% cover when present) in the canopy or subcanopy. The understory is dominated by deciduous shrubs, mostly Symphoricarpos albus 0.5-1.0 m tall (mean 44% cover), with significant amounts of the taller Amelanchier alnifolia, Oemleria cerasiformis, or Holodiscus discolor often present. The graminoids Carex inops, Poa pratensis (exotic), Melica subulata, and Elymus glaucus are usually present in small to moderate amounts, with Carex more common in the south and Melica more common in the north. Other understory species often present include the short-shrubs Mahonia aquifolium and Rubus ursinus, and the forbs Galium aparine and Lathyrus nevadensis. Many other forbs occur less frequently. This association is distinguished from similar ones by >10% cover of Symphoricarpos albus, along with >1% cover of Elymus glaucus or Carex inops, combined cover of <1% for Polystichum munitum, Circaea alpina, Maianthemum stellatum, and Claytonia sibirica, and <25% cover of Pseudotsuga menziesii.  Accession Code: VB.CC.24922.QUERCUSGARRYANA Plot-observations of this Community Concept: 0
