Resource Management

Mandalay National Wildlife Refuge, established in 1996, has a mission to conserve freshwater marsh and the species it supports, and to provide habitat for migratory birds — while providing compatible public use opportunities.

Mandalay National Wildlife Refuge is managed as a productive freshwater marsh that provides essential wintering habitat for migratory birds along the Louisiana coast. The highest priority for the Refuge is to maintain waterfowl, shorebird, and wading bird habitat. The Refuge plays a role in coastal restoration and erosion control efforts — and is a top priority wetland conservation project of the Gulf Coast Joint Venture of the North American Waterfowl Management Plan — due to the importance of its habitat for waterfowl using the Mississippi Flyway.

At Mandalay, canals and other open water areas are being affected by exotic water hyacinth and salvinia. Large floating mats of these plants can impede boat traffic and displace native plants and animals. A weevil that eats salvinia has been introduced in an effort to control this plant. To help prevent the spread of aquatic invasive species, clean your boat, equipment, and trailer before moving it between waters. To learn more about how you can help stop aquatic hitchhikers visit

Trapping Occurs on this Refuge

Trapping is a wildlife management tool used on some national wildlife refuges. Trapping may be used to protect endangered and threatened species or migratory birds or to control certain wildlife populations. The U.S. Fish and Wildlife Service also views trapping as a legitimate recreational and economic activity when there are harvestable surpluses of fur-bearing mammals. Outside of Alaska, refuges that permit trapping as a recreational use may require trappers to obtain a refuge special use permit. Signs are posted on refuges where trapping occurs.
