Alnus rubra
The forest includes lakes, bogs and wetlands, low mountains and rocky cliffs. Most of the forest has been logged once or twice, but a notable grove of low-elevation old-growth forest remains. The upper story is dominated by Pinaceae (Pine Family) including "Pseudotsuga menziesii" (Douglas-fir), "Tsuga heterophylla" (Western Hemlock), "Pinus contorta" (Shore Pine), and "Abies grandis" (Grand Fir), as well as "Acer macrophyllum" (Bigleaf Maple), "Arbutus menziesii" (Pacific Madrone), and "Alnus rubra" (Red Alder). Important understory species are "Gaultheria shallon" (Salal) and "Acer circinatum" (Vine Maple).
