Solomon Islands is the latest Pacific island nation to sign on to a new network of marine protected areas (MPAs) known as the Melanesian Ocean Corridor of Reserves, or MOCOR, which was announced by Papua New Guinea, Vanuatu and Fiji at the first Melanesian Ocean Summit in May.Located in the southwestern Pacific, Melanesia is a hotspot for marine biodiversity and the discovery of new species.While large marine corridors can be more effective than isolated MPAs, researchers caution that robust management and enforcement are necessary to prevent them from becoming so-called “paper parks.”Details about MOCOR’s size, configuration, precise location, governance, enforcement mechanisms and community consultation processes are scarce.

A group of Pacific island nations have agreed to formally establish the Melanesian Ocean Corridor of Reserves (MOCOR), a massive transboundary marine protected area (MPA) that will span their territorial waters. Papua New Guinea (PNG), Vanuatu and Fiji made a joint declaration announcing plans for the corridor at the first Melanesian Ocean Summit in May. Solomon Islands joined the initiative in late June.

Melanesia, a subregion of Oceania in the southwestern Pacific that also includes the French territory of New Caledonia and parts of Indonesia, is one of the world’s most biodiverse regions. Located in the Coral Triangle, its ocean waters contain an estimated 75% of known coral species, along with iconic marine megafauna, including sharks, rays, dugongs and whales. This part of the ocean is also a hotspot for the discovery of new species.
