About Merced National Wildlife Refuge

Merced National Wildlife Refuge conserves vital wetlands and grasslands in California's Central Valley, offering outstanding wildlife viewing opportunities, particularly for migratory birds.

Wilderness Landscape & Natural Heritage

Located in California's Central Valley, Merced National Wildlife Refuge encompasses a mix of wetlands, riparian areas, and grasslands critical for migratory waterfowl and other wildlife. Established in 1951, the refuge spans over 10,262 acres and plays a key role in protecting the Pacific Flyway with seasonal habitat for tens of thousands of ducks, geese, pelicans, and other birds. The refuge includes restored and managed wetlands, which support diverse plant and animal species including several endangered or threatened species such as the Valley elderberry longhorn beetle and riparian brush rabbit. Historically, the area was once extensive wetlands and floodplain habitat, much of which was converted for agriculture before the refuge was established to protect remaining habitats. Visitors to Merced National Wildlife Refuge can enjoy hiking on designated trails, wildlife observation at viewing platforms and blinds, guided tours during winter migration seasons, and photography opportunities. The refuge is especially popular during the fall through early spring when large flocks of sandhill cranes, snow geese, and other waterfowl arrive. Notable landmarks include the Headquarters Pond Boardwalk and the Kestrel Trail, both offering panoramic views of the wetlands and grasslands. The refuge is managed by the U.S. Fish and Wildlife Service and works closely with local partners to maintain habitat quality and support regional conservation goals. Its accessibility and rich biodiversity make it a valuable destination for outdoor enthusiasts and bird watchers seeking to experience a significant wildlife habitat in California's agricultural landscape.
