The shrub layer is well-developed and dominated or codominated by <i>Rhododendron macrophyllum</i>. <i>Gaultheria shallon</i> and/or <i>Mahonia nervosa</i> usually codominate. The well-developed herb layer is dominated by <i>Polystichum munitum</i> (always under 3% cover). <i>Linnaea borealis</i> and <i>Viola sempervirens</i> are usually present.
