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.

Réserve Naturelle de St-Martin

Better Knowledge About Protected Areas And Protected Species

The autonomous acoustic recorder installed in the waters of the Réserve Naturelle in December 2016 by three American researchers from the National Oceanic and Atmospheric Administration (NOAA) and a researcher from the University of Florida, has exceeded the expectations of these scientists. This acoustic instrument deployed at a depth of 16 meters recorded one hour every four hours over 137 days and the recordings reveal the presence of whales singing on 123 of the 137 days in question. Their songs were recorded over the entire period, from the first to the last day, signifying that the presence of these marine mammals was longer than the period of the study. The recordings from late...+ infos

Collecte de données sous-marines | Collection of underwater data

On December 4-6, 2017, the diagnostic Reef Check took place as it has every year since April 2008. This 10th edition focused on the historic site of Galion, as well as three other sites studied over the past three years: Caye Verte, Pinel, and Rocher Créole. The data collected has not yet been analyzed but little impact was noted in terms of the fauna and fixed flora (coral, gorgons, sponges...). Mobile fauna – fish and crustaceans – seems to be been disturbed and modified, but only the results of the data will determine their exact state. A minor presence of post-Irma debris was observed at the four underwater sites, especially at Rocher Créole where it is necessary to remove masts,...+ infos

Trace laissée par une tortue marine | Trace left by a sea turtle

The 50 or so eco-volunteers dedicated to reporting the egg-laying activities of sea turtles continued in 2017 with 315 patrols on the 11 beaches surveyed by the Réserve. They found 131 traces, of which 96 were reported in less than 24 hours. Green turtles left 94 of these traces, and the other 36 were by hawksbill turtles. A third of these traces resulted in the laying of eggs. Other traces were reported on the island, outside of the 11 beaches covered by the eco-volunteers, most notably eight traces of leatherback turtles, six of which were at Orient Bay. Two emergences of leatherback turtles were observed in 2017, one at Orient Bay and the other close to La Samanna, at Long Bay. Irma...+ infos

Le site BioHab de Petites Cayes en juin 2017 | The BioHab site at Petites Cayes in June 2017

Only 20 cinder blocks are left of the 300 used by the Réserve to build the nine structures of the BioHab artificial reefs implanted off the coast of Petites Cayes after hurricane Irma! What happened to the other 280 blocks of concrete? Additional investigations will take place once the sea is calm and clear, but for Julien Chalifour, scientific director, this phenomenon is hard to understand. Near Pinel, on the other hand, the artificial reef less exposed to large swells, was impacted but held fast against the elements, in spite of the shallow depth at which it is implanted.+ infos

Le même site de cornes de cerf avant et après Irma, au sud de la baie orientale The same site of Staghorn coral, to the south of Orient Bay, before and after Irma

Since November, the turbidity of the water filled with sediment, and strong swells have made it difficult to dive, so that the Réserve still has numerous sites left to evaluate post Irma. However, the hurricane badly damaged two sites identified a few years ago for their interesting density of Elkhorn coral (Acropora palmata) and Staghorn coral (Acropora cervicornis). The majority of the branches of the coral were broken and all that remains are the stumps of these colonies, while a multitude of coral fragments are strewn on the ocean floor. These two sites –North Cove Bay on Tintamare and the rocky point located to the south of Orient Bay– represented a refuge for these two species of...+ infos

Échasse d’Amérique - The black-neck stilt

Where did the birds go? The Réserve Naturelle asked itself this question the very day after Irma hit, and there really isn’t an answer. The scientific study led by Caroline Fleury and Ashley Daniel in November and December proved that there are approximately one third as many birds present as there have been at this time in previous years. Example: between 164 and 372 black-neck stilts were counted every month in 2016, and only 65 of these birds were seen in November 2017 and only nine in December. As for Anatidae, or waterfowl including the Bahama pintail duck, 102 individuals of this species were noted in December 2016 and only 43 at the same time last year. The extremely high water...+ infos

Managing The Impact Of Human Activities In Protected Areas

Following the enactment of new rules about approaching marine mammals in the waters under French jurisdiction in the Antilles last March 15, the Agoa management committee met in Martinique on November 29 and 30, to create a charter for best practices of whale watching. While the new rules prohibit any person to approach a marine mammal any closer than 300 meters, a dispensation can be provided by Maritime Affairs in the event that the person requesting it has been briefed in the best practices for whale watching, as led by Agoa in its new training sessions, and agrees to sign the corresponding charter. On November 30, the “charter for a responsible practice of commercial activities for...+ infos

Retour à la mer pour cette tortue après sa libération - Return to the sea and freedom for this turtle

Seven reports in 2017 stated that sea turtles were beached or in distress, of which four of the turtles were dead. Five of these problems were noted outside of the Réserve Naturelle. The collision with a motorboat represents the first cause of death for these reptiles that are protected in Saint Martin; the second cause of death was due to fibropapillomatosis, a herpes virus first seen in the waters of Tahiti, which now impacts sea turtles all over the world. The occurrence of this disease, normally not transmissible to humans, underlines the importance of not touching the turtles, primarily to avoid passing the disease from one individual to another. Two other turtles were almost the...+ infos

Restoration Of Degraded Areas And Populations

Déchets entreposés dans la Réserve naturelle - Trash piled in the Réserve Naturelle

In the month of September, P.C., a builder known in Orient Bay, deliberately, without the least authorization and in infraction of the rules of the Réserve, stocked bulky debris collected from Orient Bay along the edges of the Etang des Salines d’Orient, at a site protected as a natural reserve. A report is being sent to the public prosecutor’s office, and the second problem is that individuals have dumped their own trash in the same spot, thinking it was an official place to deposit debris from the hurricane. These debris have been moved since then to the ecosite. Actions de+ infos

Bénévoles et agents de la Réserve en action au Galion Volunteers and agents of the Réserve in action at Galion

Repository of an incredible quantity of debris all sizes and all kinds brought by hurricane Irma, the site of Galion has been undergoing regular cleanup operations since the month of October and is returning to its natural colors. In October, the Réserve dedicated several days to the clean up of the Galion beach and surrounding area. The staff, with the addition of 50 volunteers from the group Clean St-Martin, did a remarkable job in collecting and piling the trash collected on the beach along the side of the road, from where it was transported to the eco-site. The staff of the Réserve would like to thank all those from Verde SXM who took care of all this trash for free, Jardinia who...+ infos

Merci à What De 9 - Thanks To What De 9

What De 9, a local association in Saint Martin, in partnership with Contour Global, recently contacted the Réserve and offered to help with cleanup operations at natural sites, and also to make a donation of cleaning materials that they can provide: rakes, shovels, tools, gloves… Thanks! At the same time, the association Clean St-Martin showed their strength by undertaking the cleanup of mangrove located behind the former shelters at Orient Bay. This action complements those activities led by the Réserve, as the site in question is located outside of the Reserve’s territory and is covered with debris of all sorts. Clean St-Martin is happy to welcome all volunteers: More details available...+ infos

In mid-December, the Réserve attacked the cleanup of the small island of Pinel, focusing on an area behind the beach to the south where someone had been squatting for more than 20 years with no right to do so. Thus individual was informed that he could gather his personal affairs within two weeks, as the rest of his installation would be burned down. Irma did not spare Pinel: the pontoon and the shelter for the underwater pathway disappeared, as did one of the shelters on the discovery path, the other was essentially destroyed. The first task is to make the site secure by removing the debris that present a danger to the public. In late December, the Réserve went over to Tintamare, where...+ infos

Environmental Communication And Education

The day after Irma hit, the Réserve was already worrying about its financial capacity to repair the damage. More than half of the Réserve’s budget is based on its ability for self-financing, to the point of 470,000 euros per year, thanks to economic and eco-touristic activities authorized to operate on its most beautiful sites, but most of which will not be in operation in 2018. Knowing that the damage caused by Irma to these protected sites was estimated at close to 850,000 euros, the Réserve decided to launch a “Go- FundMe” campaign to raise money. The ideas was to invite friends of the environment to support the financing of the Réserve in its new mission, that of saving the...+ infos

Un bel article paru dans l’édition de VSD du 4 janvier 2018 © Alexis Rosenfeld A nice article appeared in the January 4, 2018 edition of VSD © Alexis Rosenfeld

In Saint Martin in mid-December 2017, journalist Alexie Valois and photographer Alexis Rosenfeld came to make a report on the state of the island almost four months after hurricane Irma hit. But their meeting with the staff of the Réserve Naturelle encouraged them to take a special interest in the island’s protected natural sites and especially the underwater milieu. This article and its exceptional photos appeared in the January 4, 2018 edition of VSD, and accents the work done over the past 20 years by the Réserve Naturelle in Saint-Martin, while indicating the huge task ahead of us before these natural areas are brought back to the good health and beauty they had before this...+ infos

Gros nettoyage en vue à l’étang de la Barrière Big clean up planned for the Etang de la Barrière

If the reconstruction of Saint Martin is advancing with baby steps, the vegetation is rapidly taking over and it is now urgent to cleanup our natural sites before the debris is completely recovered by vines and new growth. To this end, the Conservatoire du Littoral has recently called for proposal for the cleanup work on all such sites in Saint Martin, which will be done under the surveillance of the Réserve Naturelle. This operation will particularly focus on sites along the Route du Galion, the Etang de la Barrière, The Etang de Chevrise, Lucas Bay, the Salines d’Orient, The Etang aux Poissons, and the Etang de l’Anse Marcel. For example, there is a car that must be removed from the...+ infos

Better Means For Better Missions

Since hurricane Irma, life at the Réserve returned a little more to normal on November 22 with the participation of Nicolas Maslach and Franck Roncuzzi at the “Copolen,” the steering committee for the environmental police, in Guadeloupe. Organized at the request of the prosecutor’s office in Basse-Terre, the goal of this meeting was to put an operational strategy in place to control the zones protected by the environmental code. The four themes discussed by the committee were wastewater systems, urbanism, protected zones, and pollution. Director of the Réserve de Saint-Martin, Nicolas Maslach, and Franck Roncuzzi director of the office for development, surveillance, and the environmental...+ infos

Overseas Minister Annick Girardin inaugurated the exhibit, Overseas Locales (Escales Outre- Mer), on November 30 at the Ministry in Paris, accompanied by the media, school groups, and the Réserve Naturelle de Saint-Martin, represented by director Nicolas Maslach. He was able to speak with the minister for several minutes about the impact of Irma on the Réserve Naturelle and the recovery activities put in place in the months after the hurricane and those to follow. The exhibit, fruit of a collective effort throughout the overseas areas, is intended to move around France and Overseas territories for several years. There are 50 photographs that illustrate for the first time the biodiversity...+ infos

The underwater study for the Réserve Marine de Saint-Barth, which was scheduled for December 7-9, was cancelled due to bad weather conditions. The Réserve de Saint-Martin, representatives of the Réserve de Petite-Terre and of CREOCEAN had come to lend a hand to the Territorial Environmental Agency of Saint Barth, as part of their annual cooperation linked to the underwater study of marine parks. The divers tried, but without success, to unroll 150 meters of graduated ribbon along the transect. Explication: the strong swells present around the Northern Islands at the end of the year contributed to the movement of a large quantity of sediment displaced by Irma.
