Name: Quercus garryana / Symphoricarpos albus / Carex inops ssp. inops Woodland
Reference: NatureServe Biotics 2019
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 <i>Quercus garryana</i> and frequently has significant amounts of the evergreen conifer <i>Pseudotsuga menziesii</i> (mean 8% cover when present) in the canopy or subcanopy. The understory is dominated by deciduous shrubs, mostly <i>Symphoricarpos albus</i> 0.5-1.0 m tall (mean 44% cover), with significant amounts of the taller <i>Amelanchier alnifolia, Oemleria cerasiformis</i>, or <i>Holodiscus discolor</i> often present. The graminoids <i>Carex inops ssp. inops, Poa pratensis</i> (exotic), <i>Melica subulata</i>, and <i>Elymus glaucus</i> are usually present in small to moderate amounts, with <i>Carex</i> more common in the south and <i>Melica</i> more common in the north. Other understory species often present include the short-shrubs <i>Mahonia aquifolium</i> and <i>Rubus ursinus</i>, and the forbs <i>Galium aparine</i> and <i>Lathyrus nevadensis</i>. Many other forbs occur less frequently. This association is distinguished from similar ones by &gt;10% cover of <i>Symphoricarpos albus</i>, along with &gt;1% cover of <i>Elymus glaucus</i> or <i>Carex inops</i>, combined cover of &lt;1% for <i>Polystichum munitum, Circaea alpina, Maianthemum stellatum</i>, and <i>Claytonia sibirica</i>, and &lt;25% cover of <i>Pseudotsuga menziesii</i>.
