20 Réserve Naturelle SAINT MARTIN Theconservationof xenophilevegetation isone of the long-termgoalsof themanagement plan for the RéserveNaturelle. In this framework, the scientific department created an identification program for the flora on the islets of CayeVerte, Petite Clé, Pinel, and Tintamare. Financed by the French Agency for Biodiversity (AFB), this operation took place on July 15-19 and again on August 5-8, 2019, with the participation of JonathanMigeot,PhDintropicalbotanyaffiliated with ImpactMer in Martinique, as well as Karl Questel and Jonas Hochart from the Territorial Environmental Agency in Saint Barth. The four islets were investigated and special areas were defined and marked, and within each area the number and size of the plants were listed by species. This project will allow for the recons- titution of the flora on these islets over time. Thesemissions resulted in technical notes, and amore detailed reportwill be forthcoming early next year, including recommendations for the convalescence of these impacted areas. As of now, we know that important differences exist in the number and types of species on each of the foursites, but also that thepresenceofgoats and green iguanas has amajor negative impact on the vegetation by limiting the reproduction of various species, most notably certain trees. Also, based on an itinerary of the flora done in 2016 by Caroline Fleury and Karl Questel, it will be possible to evaluate the consequences of hurricane Irma on the vegetal species in the Réserve.
