Yves Merlet Integral Reserve (New Caledonia)

Weather…

The Yves Merlet Integral Reserve is the highest level of environmental protection in New Caledonia, spanning 167 square kilometers of pristine marine environment. Located between the main island of Grande Terre and the Isle of Pines, it has been strictly managed since 1970 to serve as a baseline for marine ecosystems. The 'integral' status means that all human entry is prohibited, with only rare, highly regulated exceptions for scientific monitoring. This lack of human interference allows the coral reefs and seagrass beds to thrive in their natural state, providing an undisturbed habitat for endangered species such as dugongs, green sea turtles, and various migratory seabirds. Fishing, anchoring, and transit are entirely banned, ensuring that the biodiversity remains at peak levels. The reserve acts as a biological powerhouse, where species can reproduce freely, helping to restock adjacent waters and maintaining the overall ecological balance of the South Pacific's coral sea.
