Mature forests of Picea sitchensis and Tsuga heterophylla vary with terrace level. Upper terraces have denser stands, greater numbers of Tsuga, and understories of Vaccinium, ferns, and mosses. Lower terraces have open stands with understories of Acer circinatum and grasses. Tree reproduction occurs primarily on down logs. Less than one percent occurred on ground humus. Picea reproduction numbers and survival rates are currently superior to Tsuga. Tsuga reproduction may have exceeded that of Picea earlier. Both similarities and differences exist with Fonda's Hoh River model. Picea is apparently climax in these terrace forests in contrast to other coastal types.
