Refuge Habitats and Habitat Management

You can view all of the refuge habitats from this spot: open water, freshwater wetland, field, riparian woodland, and upland woodland. This site is the future home of an environmental education shelter.

Geology of the Refuge

Standing atop a basalt outcropping overlooking the Columbia River floodplain presents an ideal opportunity to discuss the geologic forces that created the diverse habitats of the Ridgefield National Wildlife Refuge.

The Oregon White Oak Habitat

Oregon white oaks grow on both sides of this footbridge. You'll also witness forest succession, as Douglas firs threaten to replace Oregon white oaks.

Standing between large patches of reed canarygrass and Himalayan blackberry vines, you'll see firsthand just how invasive non-native species can be!
