The River View Natural Area (RVNA) is a 146-acre forested parcel connecting Forest Park to the north, Tryon State Natural Area to the south, and the Willamette River to the east. It is nestled between SW Macadam Ave and SW Terwilliger Blvd in southwest Portland. RVNA has significant ecological value - 7 streams, 130 plant species, 31 mammal species, and 74 avian species have been documented within this natural area. It comprises about half of the forest canopy in the 350-acre River View subwatershed of the Lower Willamette Watershed.
Under private ownership until 2011, the RVNA was logged in the 1800s and 1950s and subjected to vegetative neglect over the next 60 years. In July 2011, the City of Portland, in partnership with Metro and Trust for Public Land, acquired the property. It is one of the largest single natural area acquisitions in the City’s history.
