As part of the UTOPIAN project, a data acquisition spanning from August 2021 to January 2025 has allowed for the evaluation of all coral reefs in Réunion. The CORRAM method (COral Reef Rapid Assessment Method) was used, which involves estimating 8 indicators of benthic community composition through circular plots (coral cover, percentage of the genus Acropora within coral communities, algal cover, opportunistic species cover, structural complexity, diameter of the coral colony, coral state of health, density of coral juveniles). More than 5,000 circular plots have been assessed through snorkeling or freediving up to 15 meters deep. From this database, the ATLAS project is underway to spatialize all this information and compile it into an Atlas of the ecological status of the coral benthic communities of Réunion.
