Reef Project of Sainte Marie Island (PRISM)
Due to several factors including global warming, erosion, pollution and island’s economical dependance to tourism and fisheries, marine ecosystems go often through difficult times… PRISM (Reef Project of the Sainte Marie Island) has aroused from an obvious need for the study and monitoring of coral environment around Sainte Marie, for its better management and protection. In November 2017, 5 stations were identified by MAREX (la Réunion). Since then, a monitoring team was created at the Bora Dive, with the support of Cetamada, in order to monitor these locations 4 times a year and interpret the collected data.

In order to analyse biodiversity, biomass, the general state of the reef and its temporal variability, five monitoring stations were selected for their diversity and ecological specificities. On these sites, three transects of 20 meters each were deployed. Along those transects, fish and corals are identified, counted and mesured every three months.
On the long term, the Reef Project aims to bring the knowledge needed for the creation of marine protected areas (MPA) around the Sainte Marie Island. Those MPA perspectives are carried by the PCADDISM, a plateform for local consultation on sustainable development of the island supported by the COI (Indian Ocean Commission).
MAPs are a tool used for the regulation of fishing periods and areas, and of other activities impacting the reef. These regulations lower the stress imposed on the coral environment and therefore seek to reestablish the balance of its ecosystems (fish and coral recruitment, invasive species monitoring, remission of corals and zooxanthellae after a bleaching period,…).
