In May 2021 we started our first coral conservation project near Amed in Bali, Indonesia. In collaboration with the local NGO Perkumpulan Pemandu Penyelam Amed (or P3A), we are building artificial reefs that will be deployed on damaged reef areas. P3A consists of mostly Balinese divers that are committed to marine conservation. They have a lot of experience with constructing and deploying artificial reefs in the area.
The first reef restoration project is in progress in Jemeluk, east of Amed. In Jemeluk there are a few damaged reef areas consisting mostly of dead coral rubble which is slowly being taken over by algae. After an algae bloom, there is hardly any future for coral recovery. By deploying artificial structures on which coral recruits are transplanted, this once thriving reef can be restored.
We are planning to subsequently deploy different ‘coral villages’ of fixed sizes: either 10x10mtr or 10x5mtr. Every village has a predetermined layout for the deployment regarding location and types respectively quantities of the artificial structures.
Within a coral village there is a lot of variation in structures and dimensions to maximise the refuge area for different fauna. Among the villages there is a variation of the compilation of structures. The villages are mostly situated in protected marine areas, so the chances of success are optimal.
