Fish and Wildlife Service, Florida.
J.N. "Ding" Darling National Wildlife Refuge, on the subtropical barrier island of Sanibel in the Gulf of Mexico 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.
The refuge is located approximately 15 miles southwest of Fort Myers on Sanibel Island. Once on the island, turn right onto Periwinkle Drive. Proceed 3 miles to Palm Ridge Road (marked Captiva and Refuge) and bear right. Go through stop sign and continue 2 miles to refuge entrance on right.
