Protecting Wildlife and Habitat Since 1980, the Rookery Bay National Estuarine Research Reserve has worked with local partners to protect wildlife and habitat on the island while providing a wilderness recreation experience for people. Florida Department of Environmental Protection (DEP) purchased 85 percent of the 1,300-acre island at a cost of $15 million. As managers of these state-owned lands, Rookery Bay Reserve removed 300 acres of non-native Australian pine, Brazilian pepper and melaleuca that had displaced much of the island’s native habitats and wildlife. The island didn’t wash away as some predicted, but instead has flourished with native trees, plants and wildlife.
