Wilson Celini, originally from Saint Martin, is doing his undergraduate course in Biology, Chemistry and Earth Sciences at the University of Paris Sud 11. He has an internship at the Reserve from April 14th until May 31st, and his assignment is to update the biodiversity database and to develop a research tool for floral and faunal species present in the Reserve, on land and at sea. Basically, he will provide a document that will identify all species present in the Reserve, their common name in English and French, their scientific name and their principal characteristics : endangered, endemic, invasive... Painstaking work that will enable the Reserve to carry out targeted research more easily and therefore be more effective. Knowing that a scientific research assignment identified 818 species in 2012, and that this mission only concerned crustaceans (shrimps, crabs...), mollusks (snails, shells...) and echinoderms (sea urchins, starfish...), the Reserve is fully aware of the magnitude of this task, and without spelling mistakes of course!
