Located in a floodplain along the east bank of the Willamette River near Sellwood, the park is known for attracting a wide variety of birds. In 1988, the park was named Portland's first wildlife refuge,〔 and in 2004, it was designated the city's first migratory bird park. ==Description== The elongated park, which parallels the river, includes a large shallow lake on the east side of the Springwater Corridor. The Corridor is a hiking and biking path that also runs parallel to the river between Sellwood and downtown Portland. Between the lake and the Corridor is a Portland Traction rail line on a berm.〔 Slightly south of the refuge are Sellwood Park and Sellwood Riverfront Park, and Oaks Amusement Park is to the west, near the river.〔 To the east, the top of a bluff above the lake is mainly residential, though one of the buildings is a mausoleum and crematorium with a huge great blue heron mural overlooking the wetlands. A hiking trail wraps around the east side of the lake beneath the bluff. A side trail connects the east trail with Sellwood Park.〔 To the north are mixed woodlands, shrubs, and a few open fields, and a trail crossing the north section of the refuge links the Corridor to a parking lot at the top of the bluff.〔 West of the north part of the refuge are two islands, East and Hardtack, that belong to the Ross Island group in the Willamette.〔 Ross Island is the site of a heron rookery.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oaks Bottom Wildlife Refuge」の詳細全文を読む スポンサード リンク
