Coral Reefs Protected across a huge stretch of the Pacific just got a boost. Solomon Islands have become the latest Pacific nation to sign on to the Melanesian Ocean Corridor of Reserves (MOCOR), a massive transboundary marine protected area first announced by Papua New Guinea, Vanuatu, and Fiji at the inaugural Melanesian Ocean Summit in May 2026. On today's Ocean Decoded Live, host Andrew Lewin breaks down what MOCOR actually is, why it's different from an ordinary marine protected area, and what still needs to be worked out before it can deliver on its promise. The corridor sits inside the Coral Triangle, a region home to an estimated 75% of the world's known coral species, along with sharks, dugongs, rays, and whales.

Andrew explains why transboundary corridors like MOCOR matter more than isolated, single-country MPAs: marine life doesn't stop at an exclusive economic zone boundary, and industrial fishing fleets are known to simply wait at the edges of protected areas to "fish the line." He walks through the pieces already announced, including Papua New Guinea's Western Manus National Marine Sanctuary, a 214,000-square-kilometer no-take zone roughly the size of Great Britain, Vanuatu's 71,000-square-kilometer Torba National Marine Protected Area, and Fiji's pledge to protect 15% of its waters by the end of 2026. He also connects MOCOR to the global 30x30 target, and shares a quote from Yvonne Tio, executive manager at PNG's Conservation and Environment Protection Authority, on what this new MPA means for that commitment.

But announcing a corridor is not the same as protecting one. Andrew digs into what's still missing: no public maps, no published governance plans, and no confirmed enforcement mechanisms as of this recording. He also raises the concerns flagged by Watna Mori, a Papua New Guinean lawyer, about how MOCOR relates to the separate, earlier-announced Melanesian Ocean Reserve (MOR), and about whether the region's Indigenous stewards have genuinely been consulted on a framework that sits over their customary waters. This is the kind of ambitious ocean announcement worth celebrating and worth watching closely.

Takeaways:

- Solomon Islands has joined Papua New Guinea, Vanuatu, and Fiji in the Melanesian Ocean Corridor of Reserves (MOCOR), a transboundary MPA network in the Coral Triangle.
- MOCOR is a separate initiative from the previously announced Melanesian Ocean Reserve (MOR); the two use different governance models.
- Transboundary corridors are considered more effective than isolated MPAs because they protect migratory routes and reduce "fishing the line" at MPA boundaries.
- PNG's Western Manus National Marine Sanctuary, Vanuatu's Torba National Marine Protected Area, and Fiji's coastal pledge are the concrete pieces announced so far.
- Governance documents, maps, and enforcement plans for MOCOR are not yet public, raising "paper park" concerns.
- Questions remain about which Indigenous stewards were consulted before the framework was announced.
