The management association of the Réserve Naturelle de Saint-Martin is pleased to bring you up to date on our projects and activities since the beginning of 2023. This represents the fruit of hard work done by a salaried staff, as well as numerous collaborations with outside services.

In this issue, you will read about—among other subjects—the progress made by the ReCorEA project for the resilience of our coral, seagrass beds and mangroves, which will result in the overhaul and reinforcement of the mooring zone for the Réserve Naturelle. There is also an update on France Relance, concerning the installation of Biohuts in deteriorated marine zones, as well as rat control on Tintamarre in preparation to reintroduce Lesser Antilles iguanas.

These projects help achieve the goals set by the management of the Réserve Naturelle Nationale de Saint-Martin and we are proud of that achievement. We are also proud of the success met by our pedagogical department and its many different programs in the island’s schools.

You will also learn about two new nature applications : one to recognize and localize the flora and fauna on the island; and the other to contribute to the conservation of certain species—please download the apps before setting out on a hike.

We would also like to take this opportunity to thank our partners for their technical and financial support, which allows the Reserve’s management association to realize its three major objectives: manage, protect and showcase our natural heritage. We are here to promote the beauty of our island, the wealth of its flora and fauna, the characteristics of the many species or a milieu, and their importance for our quality of life and that of future generations. Our environment surrounds us and supports us at all times. We could not exist without it.
