Other groups that receive strong support include a dade containing Tepuia, Diplycosia, Gaultheria, and Pernettya (100% parjac) and Therorhodion as sister to Rhododendron + Menziesia
Coastal coniferous plots had devil's club (Oploponax horridum), rusty menziesia
ferruginea), and blueberry (Vaccinium spp.) in the shrub layer, while the Canadian coniferous plots had sparse willows and conifer saplings.

At lower elevations, there is coastal, old-growth forest of Sitka spruce (Picea sitchensis) and western hemlock (Tsuga heterophylla), with a well-developed understory (mainly Oplopanax horridus, Vaccinium spp., Menziesia
ferruginea, and Rubus spp.).
Kadashan Riparian Terrace: Vaccinium ovalifolium, 45.9%; Hylocomium splendens, 14.6%; Rhytidiadelphous loreus, 13.9%; Menziesia

Among shrubs, cover of Menziesia
ferruginea decreased in tephra plots between 1983 and 1989 and in cleared plots between 1981 and 1989 at both sites SP and SR, and did not change in either cleared or tephra plots at site DE In contrast, the dominant shrubs, Vaccinium spp., increased substantially in all these situations.
