Financed by the EU, this project aims to restore the seagrass ecosystem. This led to an analysis of the eDNA of the Bel Ombre lagoon to better understand and eventually better protect the ecosystem. This further revealed the presence of the 5 most common seagrass species in Mauritius, which are essential for the survival of 367 marine species, including many species of fish. This greater understanding of the ecosystem allows for better protection.
