La Réserve naturelle de Saint-Martin est une aire marine protégée de 30km2 située au nord-est de l’île de Saint-Martin. Créé en 1998, cet espace préserve les cinq principaux écosystèmes de l’île : récifs coralliens, mangroves, herbiers de phanérogames, étangs et forêt sèche littorale. La Réserve gère également les 14 étangs du Conservatoire du littoral et ses 11 km de rivages terrestres naturels.

Better Knowledge About Protected Areas And Protected Species

Why do female nurse sharks gather in large groups every summer, especially at Galion, but also at Caye Verte, or in Baie Blanche at Tintamare?

A university student in the Sea and Littoral Technician program at the Université du Littoral Côte d’Opale in Calais, and an intern for the French Antilles Shark Network, which is coordinated by the association Kap Natirel, Nicolas Boudin spent four months with the Réserve Naturelle studying this question. Thanks to placement of underwater cameras, he was able to determine that just the pregnant females were present at the sites that were selected to study. The fact that these sites all share the attribute of warm water,...+ infos

Depuis 2007, la Réserve naturelle poursuit son suivi scientifique annuel des récifs et herbiers, qui s’est déroulé du 4 au 6 octobre 2016. Un garde de la réserve naturelle de Petite-Terre et un autre de la réserve marine de Saint-Barth étaient présents, afin d’aider l’équipe de Saint- Martin à collecter les données sous l’eau, sur les sites du Rocher Créole, de Pinel et de Tintamare et, hors de la Réserve, sur le site de Fish Pot, dans le canal d’Anguilla. Les données sont en cours de traitement. Dans le cadre de ce compagnonnage sous-marin entre réserves, Steeve Ruillet est allé prêté main-forte à Petite-Terre du 19 au 21 septembre et Julien Chalifour à Saint- Barth du...+ infos

Une tortue verte sur l’herbier de Tintamare A green sea turtle in the Tintamare plant bed © Julien Chalifour

Already damaged by the use of anchors, the food pantry for our favorite green sea turtles has in the past few years also been invaded by a new species that is the object of tight surveillance.

Three American scientists, including Doctor Jeremy Kizska, were in Saint Martin on November 6-12 to observe the interaction between these turtles, which feed on the underwater plant beds, and Halophila stipulacea, a kind of sea grass. This invasive species was introduced via boat anchors and water from ballasts, and little-by-little takes up more-and-more space in the underwater herbier, where it is in competition with Syringodium and Thalassia, the two native species. From...+ infos

Managing The Impact Of Human Activities In Protected Areas

The management of the sea grass bed at Tintimare’s Baie Blanche, where green sea turtles feed, was the focus of a study done by Charlotte Bousquet, who was an intern at the Réserve Naturelle from February through June 2016.

A master’s student in environmental sciences and littoral ecology at the University of La Rochelle, she started by marking a map of the herbier and evaluating its overall health. Next, she did a study on the usage of the bay by various kinds of boats, noting their size, if they belonged to an private individual or a nautical professional, and if they opted to use anchors rather than mooring buoys placed there for their use by the Réserve...+ infos

Le radeau ancré sur le Grand Étang The raft anchored in the Grand Étang

In mid-October, the Réserve placed a raft in the water of the Grand Étang, in Terres Basses, in order to encourage resting and nesting for least terns, of which there are 75 on the site this year.

The idea is to protect this migratory bird, a species whose conservation status is «endangered» on a world level and «vulnerable» on the local level. Very sensitive to disturbances, the least tern makes its nest along the edge of the salt ponds, on the sand, and its eggs and not protects from a sudden rise in water levels or a hungry rat or dog. This would no longer be the case if the birds lay their eggs on the raft, out in the middle of the pond. This process exists...+ infos

Police Activity

Le portail a été saisi The gate that was confiscated

Since January 1, 2016, the agents at the Réserve Naturelle have undertaken 130 controls at sea and 147 on land, which means the latter 147 were on land belonging to the Conservatoire du Littoral. These patrols resulted in 17 fines, including two for illegal fishing, five fiscal stamps, and five in which equipment was confiscated (harpoon gun, wooden gate, crab pots, fish traps, and a net). Two inter-service missions - with the ONCFS and the Gendarmerie - conducted two fishing controls for fishing in Saint Martin. Three notices were sent by certified mail and 23 verbal warnings were issued.

Restoration Of Degraded Areas And Populations

Babit Point

The ecological restoration of damaged areas, and the global replanting of Babit Point are on the to-do list for the Conservatoire du Littoral.

Phase one of the project is to create a botany trail open to the public, with lots of informational signage and an observation point. Enclosed regeneration areas will be built and their placement has already been determined.+ infos

L’affiche de Kozé Toti The Kozé Toti poster

Protected legally in Guadeloupe since November 1991 - when they still appeared on the menu in numerous restaurants - sea turtles were in the spotlight during the 25th anniversary celebration of this protective order, which is in effect in all the French Caribbean islands.

In Saint Martin, on October 19, at The Sandy Ground Cultural Centre, the Réserve Naturelle invited the population to «Kozé Toti,» a conference led by Julien Chalifour, head of the Réserve’s scientific department, and Sophie Bedel, from ONCFS Guadeloupe (National Office For Hunting and Wildlife). Students were not excluded from the events: on October 18-21, three representatives met with 6th and...+ infos

Environmental Communication And Education

L’étang de la Barrière The Barrière pond

On September 6, 2016, the executive council of the Collectivité approved a land exchange with the Conservatoire du Littoral.

As owner of two pieces of land in the Quartier d’Orléans, the Conservatoire had suggested trading part of this land to the Collectivité in exchange for a natural site located along the edge of the Etang de la Barrière, in Cul-de-Sac. The land in the Quartier d’Orléans will be used in the construction of a new water treatment station (STEP). This trade is a win-win situation: The installation of the future STEP, designed to treat the wastewater of 18,000 residents, requires a large surface; and the Conservatoire, on the other hand, will have...+ infos

The Baie de l’Embouchure is one of eight pilot sites identified by the Conservatoire du Littoral as part of the Mang program, whose goal is to simplify the management of French overseas wetlands, in order to better preserve them.

The training of managers is planned, and in this light, the Réserve de Saint-Martin hosted ornithologist Anthony Levesque in order to strengthen the roles of Caroline Fleury and Ashley Daniel, in the field. To be able, for example, to differentiate the cry of a sandpiper from that of a chevalier, as both species were not visible at the moment they were counted during a scientific study. Run in conjunction with TeMeum and the...+ infos

Les récifs protègent de la houle la plage et la mangrove The reefs protect the beaches and mangroves from large swells

To make young people aware of the impacts of climate change on the island’s ecosystems:

that is the theme that Julien Chalifour, director of the scientific department at the Réserve Naturelle, developed for the students in the bilingual classes - French/English - at the Mont des Accords middle school, on December 9, 2015. This intervention took place in response to an invitation from the school, in conjunction with an exhibit about the environment organized by the students. When Chalifour spoke, an attentive audience learned about the responsibility of every individual to reduce his footprint in nature, or risk degrading the quality of life on one hand, and...+ infos

Caroline Fleury and Ashley Daniel represented the Réserve Naturelle de Saint-Martin at the French West Indies ornithological conference on November 9 & 10, 2016 at the National Park Center in Saint Claude, Guadeloupe.

They presented the results of scientific studies on coastal waders and marine birds, such as the white-tailed tropikbird, the least tern, and the brown noddy. They also detailed the threats to local birdlife: silt in the salt ponds, runoff of gray water, pollution... and noted the results obtained since these studies began, respectively in 2011 and 2009. Several ornithological associations also participated in this conference, including, among...+ infos

The BEST initiative has moved into high gear. As the phase for the identification of ecosystem profiles on all of the European islands in the Caribbean has been completed, the final document has been approved by the European Commission, and is now available for the public to consult on the Commission’s website.

Currently, BEST is entering into the operational phases for financing of field projects for the preservation of the region’s biodiversity. Four such projects have already been validated after the first call for projects launched in September 2015 throughout the Overseas Territories in the Caribbean, and will benefit from funding as high as 400,000 €.

Un poster qui dit tout

Laurent Juhel has designed an explanatory and highly aesthetic poster, intended to clearly inform the managers of biodiversity throughout European Caribbean.

The poster presents the BEST initiative, details about funding opportunities, how the committee of experts functions, and the first four validated projects. This poster was approved at the annual meeting of the GCFI in November 2016 in the Cayman Islands, in order to make sure all those concerned in the Caribbean are aware of this initiative.+ infos

Les 50 participants au Forum des AMP étaient notamment venus du Parc National de Port-Cros, de l’AMP de la Côte agathoise, des villes de Marseille et de Saint-Cyr-sur-Mer, des sanctuaires des mammifères marins Pelagos et Agoa, du Parc national du Morbihan, de la Réserve naturelle des Sept-Îles, de l’AMP de Moorea, de la Réserve marine de La Réunion...

The managers of Protected Marine Areas (AMP) from throughout mainland and overseas France have the opportunity to meet once a year at their annual Forum.

This year, thanks to support from the Agency for Protected Marine Areas, ATEN, and the Overseas Ministry, Saint Martin has the chance to host them! On October 25-27, 2016, at the Beach Hotel, 50 such managers were able to exchange ideas about their daily work, and share their experiences, based on common themes.
