Belize Barrier Reef is a marine landscape of coral reefs, sand cays and mangroves off Belize City. It forms part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site inscribed in 1996.
A reef system of cays, lagoons and atolls
The reef complex contains offshore atolls, coastal lagoons and estuaries, with hundreds of sand cays scattered through the system. Its seven protected areas include Bacalar Chico, Blue Hole, Half Moon Caye, South Water Caye, Glover’s Reef, Laughing Bird Caye and Sapodilla Cayes, each with a different stretch of reef and coast.
The property lies off the Caribbean coast of Belize and extends for 235 km between the Mexican and Guatemalan borders. In the northern sector, the reef lies close to the mainland; south of Belize City, the lagoon widens and the outer sites sit farther offshore. largest barrier reef and seven protected areas
World Heritage status and reef diversity
The Belize Barrier Reef Reserve System was inscribed in 1996 under natural criteria. It is the largest reef complex in the Atlantic-Caribbean region and the second largest reef system in the world.
Its value lies in the range of reef forms inside one connected property. Fringing reef, barrier reef, atolls, lagoonal reefs and patch reefs all appear within the system, alongside mangrove forests and seagrass meadows. inscribed in 1996 and second largest reef system
Life on the reef and the coastal edge
Sea turtles, manatees and the American crocodile are among the species associated with the site. The reef also supports large fish populations, coral communities and bird colonies on cays and atolls.
The landscape includes mangrove cays, littoral forest and shallow waters that change from sheltered lagoons to outer reef edge. That mix of habitats gives the property its range of plants and animals, from corals and molluscs to nesting seabirds and marine reptiles. threatened species
