Red Marker Smith and Bybee Wetlands Natural Area
Adjacent to the confluence of the Willamette and Columbia Rivers in a relatively industrial area of north Portland, Multnomah County. The site features Smith and Bybee wetlands and the closed 250-acre St. Johns Landfill, which provides grassland habitat.

Location: Adjacent to the confluence of the Willamette and Columbia rivers, in north Portland, Multnomah County. 

Description: At nearly 2,000 acres, Smith and Bybee Wetlands Natural Area is one of the nation’s largest protected urban wetlands. The perimeter of the wetlands is riparian forest, which includes approximately 15 acres of ash forest, including mature tree specimens. The IBA also includes the 240-acre St. Johns Landfill, which provides valuable grassland habitat adjacent to the wetlands.

Ornithological Highlights: Smith and Bybee Wetlands are known to host over 100 bird species. Great Blue Heron nest on site, as well as Bald Eagle, Osprey, Pileated Woodpecker, Willow Flycatcher, Marsh Wren, and Savannah Sparrow. Peregrine Falcon and Northern Harrier hunt the marshes and meadows.

Tens of thousands of waterfowl winter in the wildlife area including: Canada Goose, Green-winged Teal, Pintail,  Northern Shoveler, Mallard, Common Merganser, Bufflehead, Lesser Scaup, Ringneck Duck, American Widgeon, Gadwall, Ruddy Duck, Wood Duck, Pied-billed Grebe, Double-crested Cormorant, and Great Egret. There are also occasional sightings of Canvasback, Redheads, Blue-winged Teal, and Tundra Swan.

The only documented breeding population of Streaked Horned Larks in Multnomah County exists on the nearby Port-owned Rivergate site, and they have been observed within the wildlife area of the landfill in winter months. Metro has seeded native grasses and forbes on five acres, and has been attempting to attract breeding Streaked Horned Larks to the site.
