Wilderness Landscape & Natural Heritage
Colusa National Wildlife Refuge, located in the heart of California's Sacramento Valley, is a critical habitat for migratory waterfowl, shorebirds, and other wildlife. Established to protect wetlands and associated habitats, Colusa is managed as part of the Sacramento National Wildlife Refuge Complex. Its strategic position on the Pacific Flyway makes it a crucial resting area for millions of birds during their annual migrations. With landscapes ranging from managed wetland impoundments to grasslands and riparian habitats, the refuge provides a diverse ecological setting that supports over 200 species of birds. Visitors can explore the refuge's 4.5-mile auto tour route, two miles of walking trails, and enjoy viewing platforms that offer prime opportunities to observe large flocks of ducks, geese, and the occasional endangered species like the giant garter snake. The refuge's educational and interpretive programs enhance the visitor experience, focusing on the importance of conservation efforts in maintaining this vital ecological resource.
