BIOROCK CORAL RESTORATION-BALI:

Where BioEngineering Meets the Sacred

The Biorock Indonesia coral restoration projects in Bali and Lombok are the oldest, largest, most biodiverse, and most beautiful coral restoration projects in the world. Here is a spectacular Award-winning portfollo of the 26 year old Biorock projects in Pemuteran, Bali, whose Balinese mythological themes are lovingly documented by Maryline Renault.

In 1997 this reef was functionally dead, with almost all hard and soft corals killed by high temperature bleaching. Since we began the Biorock projects in 2000, the live coral cover in surrounding reefs has gone from around 1% to around 99% as a result of the tremendous spontaneous settlement of new species in the project, attracted by the electrical field.

Biorock Indonesia, local dive shops, and the village communities of Pemuteran, Bali, and Gili Trawangan, Lombok have made these the most successful coral restoration projects in the world, restoring full biodiversity where it had been lost. The projects are famous among underwater photographers for the extraodinary diversity of rare and beautiful reef creatures.

Biorock Indonesia, led by Dr. Beginner Subhan, Dean of the Faculty of Marine Sciences and Fisheries at Bogor University, Java, will conduct the first eDNA study of Biorock reefs in June 2026. Results of his studies will be shown here.
