The Millicoma Marsh Trail accesses one of the Coos Estuary s few remaining salt marshes. Most of the trails traverse freshwater marshes that have developed on landfill from dredge disposal activity of the shipping industry in Coos Bay. Since the last filling activity in 1985, these marshes can be seen as early successional wetland ecosystems. Wetland grasses, rushes, sedges, and cattail are well established. Willow, Red alder, shore pine, sitka spruce, madrone, and Douglas-fir are providing more cover for wildlife.
