There is a great CNN special about the coral reefs having many species that are extinct elsewhere. They are protecting the reefs from tourists very carefully. I just had to do a quick search to check:
Named for Queen Isabella of Spain 500 years ago by Christopher Columbus, the Gardens of the Queen (Jardines de la Reina) archipelago is a string of hundreds of mangrove-fringed islets and keys stretching over 150 kilometers along Cubas southeastern coast. Still nearly devoid of human footprints today, the area is a window into the Caribbean as it looked in Columbus time, says Dan Whittle, director of EDFs Cuba program.
In the 1990s, the Cuban government set aside the Gardens as an 850-square-mile marine reservethe biggest in the Caribbeanas part of a planned island-wide network designed with help from EDF. With commercial fishing and other damaging activities restricted, the area, now a national park, provides a baseline for gauging the health of sea life and habitat in adjacent areas where such activities are not curtailed.
With no inhabitants and only several hundred divers allowed each year, this highly productive, biodiverse area contains some of the most pristine coral reefs left in the Caribbean and remains a haven for fish and other sea life. The reserve has large populations of sea turtles, including hawksbill and green, and an abundance of sharks, huge groupers and thick seagrass meadowsall indicating an ecosystem in balance.
Were working with our Cuban partners to conduct research and develop management strategies for the Gardens. The reserve, together with the Canarreos archipelago on the southern rim of the Gulf of Batabano, has been proposed as a World Heritage Site. This 500-mile-long stretch, which includes nine protected areas, is the subject of a five-year Global Environmental Facility (GEF) project on ecological reserves and coral reefs.
Pairing marine reserves with incentives for fishermen
Illegal fishing and conflicts with fishermen are major threats to protected areas throughout the Caribbean. In the Gardens, enforcement is a big issue. For cash-strapped Cuba, patrol boats are prohibitively expensive. But, with the right incentives, fishermen can be persuaded to help conserve the resource. For example, by granting fisherman the rights to fish on the edges of protected areas where abundant fish spill over into fishing grounds, they can become partners instead of adversaries.
