Roughly 75 percent of the Caribbean's coral reefs are threatened--with more than 30 percent ranking in the "high" or "very high" threat category. But one reef system in Cuba, Jardines de la Reina (the "Gardens of the Queen"), offers great lessons—and hope—for effective coral reef management.


Raising awareness of threats to coral reefs and providing information and tools to manage coastal habitats more effectively.

More than one-quarter of the world’s reefs are threatened by watershed-based pollution (including nutrient fertilizers, sediment, pesticides, and other polluted runoff from the land), with about 10

At present, local human activities (overfishing and destructive fishing, marine-based pollution and damage, coastal development, and watershed-based pollution) threaten an estimated 60 percent of the

Mapping of past thermal stress on coral reefs (1998–2007) suggests that almost 40 percent of reefs may have been affected by thermal stress, meaning they are located in areas where water temperature

Approximately 370 observations of coral bleaching were reported globally between 1980 and 1997, while more than 3,700 were reported between 1998 and 2010.

The world’s coral reefs cover an area of approximately 250,000 sq km, with the highest concentrations in Southeast Asia and the Pacific.

One-eighth of the world’s population—roughly 850 million people—live within 100 km of a coral reef and are likely to derive some benefits from the ecosystem services that coral reefs provide.


In the ICRAN Mesoamerican ReefAlliance (ICRAN-MAR), several partners have come together in a three-year initiative to support regional efforts in response to the Tulum Declaration of 1997 for the conservation of the Mesoamerican Barrier Reef (Mexico, Belize, Guatemala, and Honduras).
