Wilderness Landscape & Natural Heritage
The Scappoose Bay Watershed Natural Area encompasses approximately 1,200 acres of wetlands, tidal marshes, floodplains, and upland forest located in Columbia County, Oregon. This protected area is part of the larger Scappoose Bay watershed, which drains into the northern end of the Columbia River. The landscape is characterized by tidally influenced wetlands, freshwater sloughs, and riparian corridors that support vibrant populations of native fish, amphibians, and over 100 species of birds, including migratory shorebirds and waterfowl. Efforts to restore tidal flows and native vegetation have enhanced the natural functions of the estuarine environment, making it a vital stopover for migrating birds and a nursery for juvenile fish such as salmon and sturgeon.
Historically, this area was used by Indigenous peoples for fishing and gathering, and today conservation initiatives focus on habitat restoration and protection from invasive species and development pressures. Visitors to the area find well-maintained trails for hiking and wildlife observation, with opportunities to explore unique habitats such as sitka spruce forests, wet prairie, and tidal marshes. The nearby Columbia River provides additional recreation through boating and fishing, while the natural area itself supports educational outings and birdwatching expeditions.
Accessible year-round, the natural area offers a quiet outdoor experience close to the Portland metropolitan area. Interpretive signage helps visitors understand the ecological importance of the watershed and the ongoing restoration efforts. With its mix of upland and wetland habitats, the Scappoose Bay Watershed Natural Area is a significant refuge for native species and a valuable outdoor resource for local communities and visitors alike.
