The goals of Mackay Island National Wildlife Refuge are restore, enhance, and maintain the health and biodiversity of brackish marsh, forests, and other habitats to ensure optimum ecological productivity and protect the water quality of Currituck Sound and Back Bay. 

Basic measurements and data collecting on the health of the ecosystem and wildlife is taken, but no specific studies are being conducted on Mackay Island currently. Some of our other refuges in the complex such as Alligator River and Currituck are conducting studies that can be reached through their respective websites.
