Colusa National Wildlife Refuge
The Sacramento National Wildlife Refuge, established in 1937 under the Emergency Conservation Fund Act of 1933, plays a crucial role in providing a sanctuary for migratory birds and various wildlife species. Originally known as the Colusa Plains, the area was a windswept expanse of grasses and shrubs before the federal government acquired the 10,775-acre Spalding Ranch. From 1937 to 1942, the Civilian Conservation Corps (CCC) worked tirelessly to transform this landscape, constructing essential infrastructure to create and maintain wetlands, which laid the foundation for the refuge's current ecosystem.
Today, the Sacramento National Wildlife Refuge serves as the headquarters for the entire Sacramento National Wildlife Refuge Complex and supports over 250 bird species. Notable for its massive wintering populations, the refuge sees peaks of over 500,000 ducks and 250,000 geese between November and January, attracting numerous raptors such as bald eagles and peregrine falcons. Birdwatching opportunities are abundant year-round, with waterfowl viewing best from October to March and shorebird numbers peaking during spring and fall migrations. Summer months feature nesting waterfowl and migratory songbirds, providing diverse wildlife viewing experiences.
The mission of the National Wildlife Refuge System is to manage a nationwide network of lands and waters dedicated to the conservation and restoration of fish, wildlife, and plant resources and their habitats. This mission ensures that these natural resources are preserved and available for the benefit and enjoyment of current and future generations of Americans, aligning with the refuge's ongoing efforts to protect and sustain its vibrant ecosystems.
