Conifers are the characteristic trees, and the predominant species are Sitka spruce "(Picea sitchensis)", western hemlock "(Tsuga heterophylla)", and mountain hemlock "(Tsuga mertensiana)", together with shore pine "(Pinus contorta)", western red cedar "(Thuja plicata)", and yellow cedar "(Callitropsis nootkatensis)".
