Safeguarding one of the most
bio-diverse places in the world
We have been working to spread awareness on coral conservation, setting up coral nurseries and restoration sites across Indonesia since 2016.

ABOUT US
Ocean Gardener stands as a beacon of hope for the coral reefs of Indonesia. Established in 2016, we are a diverse team of biologists, divers and enthusiasts. We rely on 25 years of coral farming experience in Indonesia to drive our education and restoration efforts.
We partner with local communities, hotels, resorts and dive shops to setup and deploy coral nurseries using our protocols ensuring good rates of survival. From these nurseries, we harvest donor coral colonies to restore the surrounding reefs.
Collectively with our partners, we have planted over 1 million corals, with over 200,000 corals planted in the last few years through large scale coral reef restoration projects.
We offer tours for the public to learn about coral restoration and courses for people wanting more hands-on and in-depth knowledge.
