Rot-Erle
Gottesfeld could detect 21 species, which played a certain role as CMTs. Of utmost importance is the Western red cedar ("Thuja plicata"), but the yellow cedar ("Chamaecyparis nootkatensis"), spruces ("Picea glauca" u.a.), hemlock ("Tsuga heterophylla"), pines ("Pinus contorta", "Pinus ponderosa"), in addition "Populus tremuloides", "Populus trichocarpa" and "Alnus rubra" are also quite frequent. The bark of hemlock and certain spruces was important for nourishment and medicine. The resin of spruces was used as a kind of glue.
