A counter to track the state of overseas biodiversity, understand it better and act better, was launched at the beginning of September on the occasion of the World Conservation Congress, which was held in Marseille. Developed by the National Museum of Natural History and the French Biodiversity Office, it highlights the challenges of biodiversity in overseas territories. It also gives citizens a set of encrypted and documented information so that they can be, on their scale, actors in the preservation of the exceptional natural heritage of overseas territories. Several scientific databases have been connected together on a web portal : to discover on https://biodiversite-outre-mer.fr
