Average shrub cover is 60% and <i>Oplopanax horridus</i> dominates the tall-shrub layer, sometimes codominating with <i>Rubus spectabilis</i>. Low shrubs are absent. The forb layer averages 25% cover and <i>Circaea alpina</i> dominates. Fern cover averages 60% including <i>Athyrium filix-femina</i> and <i>Gymnocarpium dryopteris</i>.
