The National Wildlife Refuge System Improvement Act of 1997 requires the U.S. Fish and Wildlife Service to develop a comprehensive conservation plan by 2012 for each national wildlife refuge. In September 2008, the Service approved the plan for the 12 national wildlife refuges, which will guide management of the refuges for the next 15 years.
