Book excerpt: Located in the northern Willamette River basin, Tualatin River National Wildlife Refuge (Refuge) was established in 1992 with an approved acquisition boundary to accommodate willing sellers with potentially restorable holdings within the Tualatin River floodplain. The Refuge's floodplain of seasonal and emergent wetlands, Oregon ash riparian hardwood, riparian shrub, coniferous forest, and Garry oak communities are representative of remnant plant communities historically common in the Willamette River valley and offer an opportunity to compensate for wildlife habitat losses associated with the Willamette River basin federal hydroelectric projects. The purchase of the Oleson Units as additions to the Refuge using Bonneville Power Administration (BPA) funds will partially mitigate for wildlife habitat and target species losses incurred as a result of construction and inundation activities at Dexter and Detroit Dams. Lands acquired for mitigation of Federal Columbia River Power System (FCRPS) impacts to wildlife are evaluated using the Habitat Evaluation Procedures (HEP) methodology, which quantifies how many Habitat Units (HUs) are to be credited to BPA. HUs or credits gained lessen BPA's debt, which was formally tabulated in the FCRPS Loss Assessments and adopted as part of the Northwest Power and Conservation Council's Fish and Wildlife Program as a BPA obligation (NWPCC, 1994 and 2000). There are two basic management scenarios to consider for this evaluation: (1) Habitats can be managed without restoration activities to benefit wildlife populations, or (2) Habitats can be restored using a number of techniques to improve habitat values more quickly. Without restoration, upland and wetland areas may be periodically mowed and disced to prevent invasion of exotic vegetation, volunteer trees and shrubs may grow to expand forested areas, and cooperative farming may be employed to provide forage for migrating and wintering waterfowl. Abandoned cropland would comprise over half the total acreage and may be mowed or hayed to reduce exotic vegetation. Grasslands and wetlands may similarly be mowed or hayed, or left fallow. Wetlands would be subject to periodic flooding from the Tualatin River, but would drain quickly and promote undesirable vegetation. Riverine, forested wetland, and mixed forest habitats would likely change little from their current condition. Active restoration would include restoring wetlands with limited use of dikes and water control structures; planting and maintaining native grass, trees, and shrubs; and aggressive management of non-native invasive vegetation. Hydrology would be restored to emergent wetlands mimicking natural cycles thus promoting hydrophytic vegetation beneficial to fish and wildlife. Grassland and former crop areas would be planted with native grasses and trees to recreate prairie and savanna habitat types. Riverine riparian and forested wetland areas would be expanded by planting native trees and shrubs benefiting a multitude of species. Although a 'hands off' approach may provide habitat benefits after many decades, a more proactive approach would provide far more benefits to fish and wildlife, and thus would provide additional habitat credits more quickly.

Finley National Wildlife Refuge. Excerpt: The Tualatin River National Wildlife Refuge is a 1,856 acres (751 ha) wetlands and lowlands sanctuary in the northwestern part of the U.S. state of Oregon. Established in 1992 and opened to the public in 2006, it is managed by the United States Fish and Wildlife Service. Located in southeastern Washington County, 15 miles (24 km) southwest of Portland, the refuge is bordered by Sherwood, Tualatin and Tigard. A newer area, extending into northern Yamhill County, is located further west near the city of Gaston surrounding the former Wapato Lake. Part of the network of National Wildlife Refuges (NWR), the Tualatin River refuge is one of only ten urban refuges in the United States. Habitats in the refuge include...
