The U.S. Fish and Wildlife Service (Service) has prepared this Comprehensive Conservation Plan (CCP) to guide the management of Lacassine National Wildlife Refuge in Cameron and Evangeline Parishes, Louisiana. Lacassine, Cameron Prairie, Sabine, and Shell Keys Refuges comprise the Southwest Louisiana National Wildlife Refuge Complex. The CCP outlines programs and corresponding resource needs for the next 15 years, as mandated by the National Wildlife Refuge System Improvement Act of 1997.
