Rebuilding the reef in French Polynesia

Island innovators are restoring 10,000 “super corals” to the reef to save wildlife habitat and spread global awareness.

Key facts

Only One members are funding the planting of 10,000 corals in the crystal waters of Mo'orea, a volcanic island in the Pacific 11 miles northwest of Tahiti

The project is rebuilding the reef with corals more able to withstand climate change, protecting ocean wildlife, and benefiting local people.

Mo'orea is surrounded by 13 marine protected areas. Marine reserves like these are vital for securing a positive future for the ocean.

Our coral planting partner Coral Gardeners is the brainchild of Titouan Bernicot, an ocean kid who loved his island’s magnificent reef ecosystem and dreamed big!

How the project works


Coral Gardeners identifies and collects “super coral” fragments in the wild.

The coral fragments are cleaned and seeded in nurseries, where they increase in size and multiply over time.

Every day, the reef restoration team at Coral Gardeners monitors the corals’ growth and health.

Once the corals are mature enough, Coral Gardeners takes them to a reef and plants them, helping bring life back to the ocean.

Project impact

All projects on Only One help save the ocean and fix the climate, and 100% of our members’ funds go to impact. Keep reading to discover how our “Rebuilding the reef in French Polynesia” project is having a positive effect.

Biodiversity and ecosystems

Located in the Pacific, Mo'orea is one of the Society Islands in French Polynesia. The tropical island is protected by coral reefs home to hundreds of species, from clams, crabs, lobsters, sponges, and fish, to sharks, rays, turtles, and dolphins. The song of humpback whales can be heard seasonally. Mo'orea is surrounded by 13 marine protected areas, all of which are vital for securing a positive future for the ocean — the project’s transplantation area is close to a marine sanctuary. The corals planted on behalf of Only One members will bring more biodiversity to Mo'orea’s lagoon, benefiting nature and local communities.

Wildlife protection

Coral reefs are one of the most diverse habitats on the planet, supporting 25% of all ocean creatures! When reefs bleach or die due to pressures like heat waves and ocean acidification, marine species lose their home. Coral Gardeners are planting stress-resistant corals, giving Mo'orea’s reefs the best possible chance of survival and meaning ocean wildlife is more likely to thrive long term. The project’s transplantation area protects an important habitat.

Community development

Coral Gardeners hires local people in Mo'orea like former fisherfolk and surfers, giving them a more consistent source of income. They have 23+ permanent employees and interns.

Sustainable Development Goals

Only One members’ funds go toward projects corresponding to the United Nations’ Sustainable Development Goals (SDGs). The SDGs our “Rebuilding the reef in French Polynesia” project supports are:

Project reporting

Coral Gardeners will send Only One a quarterly report on how the coral planting project is progressing, including an analysis of survival rates three months in. As of June 2022, a total of 7,940 corals from Coral Gardeners’ Tiaia nursery have been trimmed and officially transplanted to the reef. Their growth and survival rates will follow in the coming months, so watch this space!

More about our coral planting partner

Coral Gardeners was born in 2017 on the island of Mo'orea in French Polynesia, when a small group of island kids who were witnessing the rapid degradation of the coral reef around them decided to take action. From humble beginnings, Coral Gardeners has grown into an international collective of advocates, scientists, engineers, and creators determined to build a global movement to save the reef. Their team grows and plants “super corals” using the latest techniques, pushing the boundaries of technology in ocean conservation, and they scale their impact globally so everyone can join their mission.
