Refuge Habitats and Habitat Management

There are five distinct habitats in the refuge. Explore each of these habitats and discover how the U.S. Fish and Wildlife Service conserves, protects, and enhances them.

Geology of the Refuge

Powerful geologic forces created the diverse habitats of the Ridgefield National Wildlife Refuge. Discover how lava flows and glaciers helped to form these natural communities.

The Oregon White Oak Habitat

The Oregon white oak is Washington's only native oak. Learn why these oaks thrive in the refuge and how they're being protected.

Endangered and Invasive Species

Non-native plants introduced through human activity compete with native plant and animal species. Discover which species are invasive, which are endangered, and what you can do to help restore native species.

Some of these games and puzzles will prepare you for your field trip, while others will enhance your experience while you're on the refuge.
