A controlled safe zone where corals can survive rising seas
Coral reefs, which shelter a quarter of all marine life while covering less than one percent of the ocean floor, have long absorbed the compounding pressures of a warming world largely in silence. On World Oceans Day 2026, the Beyond Green network of luxury resorts offered a counterpoint — demonstrating that hospitality, often cast as an agent of environmental harm, might instead become a vehicle for restoration. Across six continents, from Zanzibar to French Polynesia, these properties are deploying nurseries, reef structures, and guest participation programs in a quiet argument that conservation and commerce need not be opposites.
- Coral reefs are collapsing under the weight of climate change, bleaching events, and coastal development, with a catastrophic global bleaching event in early 2024 accelerating the crisis.
- The Beyond Green network is responding with urgency — deploying reef stars off Zanzibar, running coral adoption programs in Costa Rica, and cultivating nursery tanks in Dominica's hurricane-scarred waters.
- Guests are being transformed from passive tourists into active participants — tagging corals, attaching reef fragments, and contributing to scientific monitoring in places like Corcovado National Park.
- Local communities are woven into the restoration work, from Zanzibar residents building hexagonal reef frames to Colombian divers trained as coral gardeners, creating livelihoods alongside ecosystems.
- The initiative signals a broader repositioning: luxury hospitality, evaluated against UN Sustainable Development Goals, is staking a claim as a scalable force for marine conservation rather than a driver of its decline.
Coral reefs cover less than one percent of the ocean floor, yet they sustain roughly a quarter of all marine life — making them both irreplaceable and acutely vulnerable. Climate change, bleaching, pollution, and overdevelopment have placed them under relentless strain. On World Oceans Day 2026, the Beyond Green network of sustainable luxury resorts used the occasion to demonstrate what a different kind of hospitality might look like.
Off Zanzibar's coast, andBeyond Mnemba Island has anchored 101 hexagonal reef stars to the seafloor since late 2025 — structures built by local community members that stabilize broken coral and host nursery-grown fragments. The program was born from the damage wrought by a global bleaching event in February 2024, and guests can participate directly by attaching coral pieces before deployment. In Costa Rica's Corcovado National Park, the Corcovado Wilderness Lodge invites visitors to become community scientists — identifying, tagging, and tracking corals in partnership with marine research organizations.
On the island of Dominica, the fully off-grid Coulibri Ridge resort supports a Coral Rescue Center named for a conservationist who championed reef protection after Hurricane Maria. The center operates nursery tanks as a controlled safe zone, cultivating corals intended for eventual ocean replanting. In Malaysia, Gayana Marine Resort runs a research center focused on giant clam propagation and reef regeneration. In Colombia, Hotel Las Islas has planted 90,000 corals alongside the local Barú community, training divers as coral gardeners and weaving sustainable livelihoods into the restoration work.
On Tetiaroa — the private French Polynesian atoll once owned by Marlon Brando — The Brando resort supports a nonprofit dedicated to the atoll's protection, funding research and a restoration program that removes invasive species and plans to reintroduce sea turtles and seabirds, creatures whose presence is itself vital to reef health.
Beyond Green, which operates more than 100 properties evaluated against UN Sustainable Development Goals, is making a deliberate argument: that luxury travel, long seen as a threat to fragile ecosystems, can be redesigned as a force for their recovery — scaling conservation while generating opportunity for the communities living closest to the sea.
Coral reefs occupy less than one percent of the ocean floor, yet they shelter roughly a quarter of all marine life. They are among the planet's most vital ecosystems and also among its most fragile. Climate change, bleaching events, pollution, overfishing, and coastal development have placed them under relentless pressure. On World Oceans Day 2026, a network of luxury resorts called Beyond Green used the occasion to highlight what they are doing to fight back.
The network spans continents and approaches. Off the coast of Zanzibar, andBeyond Mnemba Island has deployed 101 hexagonal structures called reef stars since November 2025. Built by local community members and anchored to the seafloor, these frames stabilize broken coral and create surfaces where nursery-grown fragments can take hold. The initiative, called Reef Stars, emerged from the Oceans Without Borders program, a marine conservation effort founded by andBeyond and Wild Impact in 2018. It was designed specifically to address the damage from a global mass coral bleaching event in February 2024 that devastated Mnemba's reefs. Guests at the island resort can participate directly, attaching coral fragments to the frames before they are deployed.
In Costa Rica's remote Corcovado National Park, the Corcovado Wilderness Lodge by SCP has created an "Adopt a Coral" program in partnership with Innoceana and Restor Laboratories. Visitors become community scientists for a day, identifying and tagging corals, tracking their evolution, testing their immunology, and documenting findings. The lodge sits within 450,000 acres of protected reserves and offers guests the chance to contribute to systematic reef monitoring while experiencing the landscape.
On the island of Dominica, Coulibri Ridge—a fully off-grid luxury resort powered entirely by renewable energy and rainwater—supports the Soufrière-Scott's Head Marine Reserve coral restoration effort through its affiliated REZDM organization. The reserve was established to protect underwater features, preserve traditional fishing practices, and ensure the resource endures for all users. In 2024, the Coral Rescue Center was named after Daniel Langlois, who championed protection of vulnerable coral species after Hurricane Maria devastated the region. The center operates as a controlled "safe zone" away from the sea, housing nursery tanks where corals are monitored daily. The long-term goal is to cultivate living coral specimens that can eventually be replanted on the reefs as ocean temperatures continue to rise.
In Malaysia, Gayana Marine Resort in Kota Kinabalu operates the Marine Ecology Research Centre, which focuses on giant clam propagation and coral reef regeneration. The center advances research and education while offering guests hands-on coral replanting activities. In Colombia, Hotel Las Islas near Cartagena has planted 90,000 new corals in partnership with the local Barú community. The hotel trains divers as coral gardeners, creating both reef restoration and sustainable livelihoods.
On Tetiaroa, a private atoll in French Polynesia once owned by actor Marlon Brando, The Brando resort supports the Tetiaroa Society, a nonprofit dedicated to protecting the atoll. The resort fulfills Brando's original vision of a "university of the sea" by leading ocean research and supporting the Tetiaroa Atoll Restoration Program, which removes invasive species and plans to reintroduce endangered native species like sea turtles and seabirds—creatures that themselves play crucial roles in reef health.
Beyond Green, operated by Preferred Hotels & Resorts, is a global community of sustainable travel leaders. The network includes more than 100 member properties evaluated against sustainability indicators aligned with United Nations Sustainable Development Goals. The organization also provides consulting services to destinations and hospitality brands seeking to build sustainability strategies. By showcasing these initiatives on World Oceans Day, Beyond Green is positioning luxury hospitality not as a threat to marine ecosystems but as a potential force for their restoration—one that can scale conservation efforts while creating economic opportunity for local communities.

The Hearth Conversation Another angle on the story
Why does a luxury resort network care about coral reefs? Isn't this just marketing?
Some of it may be, but the work is real. These aren't token gestures. Mnemba Island has deployed 101 structures and trained community members to build them. Coulibri Ridge is running a daily-monitored coral nursery. Hotel Las Islas has planted 90,000 corals. That's material action.
But can guests really make a difference by attaching a coral fragment for an afternoon?
Not alone, no. But it changes how people think about the ocean. You can't spend a day as a community scientist or hand-plant a coral and then go home indifferent. The resorts are betting that experience creates advocates—people who will vote differently, travel differently, pressure their own communities to act.
What about the communities living near these resorts? Are they benefiting or just being used as labor?
That varies. In Colombia, Hotel Las Islas explicitly works with the Barú community and trains divers as coral gardeners—that's sustainable livelihood, not just jobs. In Zanzibar, the reef stars are built locally. But the source doesn't detail wages, training depth, or long-term economic security. That's a real question worth asking.
If climate change keeps warming the ocean, do coral nurseries actually matter?
They're a hedge. The Dominica center is explicitly designed as a "safe zone" away from rising sea temperatures—a way to preserve genetic diversity and potentially breed heat-resistant corals. It's not a solution to climate change. It's insurance while we figure out the larger problem.
What's the scale here? How much of the world's reefs are these resorts actually protecting?
Tiny. Negligible in global terms. But they're proving the model works and creating infrastructure that could scale. If luxury hospitality becomes a standard vector for conservation funding and community engagement, that changes the math.
