About J.N. "Ding" Darling National Wildlife Refuge
J.N. "Ding" Darling National Wildlife Refuge, on the subtropical barrier island of Sanibel in the Gulf of America along Florida’s west coast, is part of the largest undeveloped mangrove ecosystem in the United States. It is world famous for spectacular migratory bird populations. The refuge was established in 1945 to safeguard and enhance the wildlife habitat of Sanibel Island, to protect endangered and threatened species, and to provide feeding, nesting, and roosting areas for migratory birds. In 1967, the refuge was renamed for conservation pioneer Jay Norwood “Ding” Darling, who was instrumental in its founding. More than 40 percent of the refuge is Congressionally designated wilderness.
