      What We Do

        

      • Resource Management

      To help plants and wildlife, Refuge staff uses a variety of habitat management techniques to maintain, recover or enhance plant and wildlife values. Refuge staff carefully consider any management techniques and employ them in varying degrees according to the situation.

      • Conservation and Partnerships

      The Complex is involved in many conservation endeavors, including Comprehensive Conservation Plans, Private Landowner Programs, and the National Wildlife Refuge System Improvement Act.

      Our Organization

      National Wildlife Refuge System Improvement Act of 1997:The NWRS Improvement Act defines a unifying mission for all refuges, including a process for determining compatible uses on refuges, and requiring that each refuge be managed according to a CCP. The NWRS Improvement  Act expressly states that wildlife conservation is the priority of System lands and that the Secretary shall ensure that the biological integrity, diversity, and environmental health of refuge lands are maintained. Each refuge must be managed to fulfill the specific purposes for which the refuge was established and the System mission. The first priority of each refuge is to conserve, manage, and if needed, restore fish and wildlife populations and habitats according to its purpose.

      The U.S. Fish and Wildlife Service manages an unparalleled network of public lands and waters called the National Wildlife Refuge System. With more than 560 refuges spanning the country, this system protects iconic species and provides some of the best wildlife viewing opportunities on Earth.

      Our Species

      Colusa NWR regularly supports peak wintering populations of over 150,000 ducks and  60,000 geese. Thousands of waterfowl are present from September through March. Peak populations occur in December and January. Many birds including nesting wood ducks and mammals can be seen year-round.
