Wilderness Landscape & Natural Heritage
Graham Oaks Nature Park is a 250-acre natural area located in Wilsonville, Oregon, managed by Metro. The park is situated in the Willamette Valley region and encompasses a variety of ecosystems, including native oak savannas, wetlands, and mixed hardwood forests. The site was formerly an agricultural area and was restored to promote native plant communities and attract wildlife. Visitors can explore over 4 miles of trails that wind through prairies and wooded areas, with interpretive signage offering educational insights into the local ecology and restoration efforts. The park is home to diverse wildlife such as songbirds, raptors, amphibians, and native plants like Oregon white oak, camas lily, and trillium. Notable features include a large picnic shelter, natural play areas for children, and open meadow spaces ideal for birdwatching and photography. Graham Oaks serves as both a recreational area and a living classroom, welcoming families, nature enthusiasts, and educators. Its close proximity to urban centers like Portland and Salem makes it an accessible destination for day hikes, nature observation, and environmental education programs. The park is also important as one of the region's efforts to preserve remnant oak habitat, which has declined significantly in the Willamette Valley due to urbanization and farming.
