Waterways is a series of mini-documentaries that explore the natural and cultural heritage of South Florida's public lands. Waterways is a cooperative effort between the National Park Service and the following partners: South Florida National Parks Trust, Environmental Protection Agency and Florida Keys National Marine Sanctuary.

Elkhorn/Staghorn Listed. Staghorn and Elkhorn corals were historically the visual and ecological centerpiece of reefs throughout the Florida Keys, particularly in Biscayne National Park. In response to recent major declines in both Acropora species, they were listed as threatened under the Endangered Species Act—the first corals to make the list. Volunteers help the Park Service find and monitor Acropora colonies to aid in a recovery program for the species.
