(2025 IMPACT REPORT) — CORAL GARDENERS

We didn't reach our goal.

Because we changed our definition of impact.

Restoration isn't a fixed science.

What worked yesterday may not be enough for tomorrow's climate. So our approach has to evolve with it.

01

Ecosystem Restoration

Our strategy is more than just planting corals — it focuses on growing resilient corals and cultivating ecosystems that can recover and thrive over time, creating a network of coral reef oases across the ocean.

Our impact goes beyond planting corals.

Discover why

Scaling restoration across the ocean.

We're now working on 12 sites across three branches in French Polynesia, Thailand, and Fiji — and have begun exploring new reef systems in the Mediterranean.

CG Labs: Science & Innovation

Our CG Labs team of engineers and scientists continued to develop and advance our ReefOS system — a suite of tools built to monitor the entire restoration process. Across all our sites, the gardeners use these tools to track the corals we plant, monitor, and outplant.

Developing our biggest innovations yet.

In 2025, CG Labs introduced the launch of spatial intelligence, enabling advanced monitoring through AI-powered image analysis and photogrammetry, providing unprecedented insights into reef ecosystems.

People

We're offering anyone the power to garden the ocean back to life. Over the years, our grassroots project has grown into a global movement powered by millions. By making conservation accessible, we want to give everyone the power to revive the ocean, one coral at a time.

Coral gardening — officially the world's coolest job.

We believe that people who should be restoring the reef are those who know it best. That's why we put our blueprint methodology and tools developed in collaboration with CG Labs into the hands of the people who live near the reef and already have a relationship with it.

In June 2025, at the United Nations Ocean Conference (UNOC) in Nice, the French Polynesian government announced its support to recognize coral gardening as an official profession — creating a path for more people to make a living caring for the reefs they call home.

Funding

Funding the future of the reef isn't optional. Coral reefs are relied upon by millions of people and marine species, and protecting something this vital requires more than just a traditional NGO model. Since our beginning, we have raised more than $19 million for the reef.

Saving the reef isn't cheap — but what's the cost if we don't?

Reef restoration is no longer a question of possibility, but of speed, scale, and collective will.

We see a future that gives power to the gardeners — where anyone, anywhere can garden the world back to life.
