Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems

The Lagoons of New Caledonia are a series of fringing, barrier and atoll reef systems around Grande Terre and the Loyalty Islands, recognized for exceptional coral diversity and extensive lagoonal habitats.

Shallow lagoons fringed by coral reefs, seagrass beds and mangroves create a mosaic of habitats that support coral and fish diversity; snorkeling and scientific observation reveal abundant reef life in clear, sheltered waters. Reef structures form long barrier systems along parts of Grande Terre’s east coast and surround islands in the Loyalty group.

These reef systems developed over millennia through coral growth and sea-level change; they have been used traditionally by local communities and studied in modern times for their ecological importance. Contemporary conservation measures focus on protecting reef integrity and species diversity.

The property stretches along the east coast of Grande Terre and includes multiple island and lagoon components in the Loyalty Islands, located in the South Pacific within New Caledonia’s territorial waters.

• Multiple reef and lagoon components: The property comprises multiple marine and coastal components that together preserve high coral diversity and associated ecosystems such as seagrass beds and mangroves.
• Conservation emphasis: Conservation focuses on reef health and species diversity across shallow lagoonal environments and barrier reef formations.
