Monitoring of marine mammals

For several years the Nature Reserve collect data on marine mammals thanks to observations of the population (fishermen, individuals...). These data on the number of marine mammals, their location and direction were transmitted, then synthesized by scientists.
In 20 years, twenty-three species of marine mammals have been recorded off the coast of Guadeloupe, Martinique, Saint-Martin and Saint-Barthélemy. These data have helped to create a sanctuary for marine mammals.


Sanctuary for marine mammals Agoa was born in 2010 by decision of the French Government. Its creation responds to a Grenelle of the Sea’ commitment.
It extends across the Exclusive Economic Zones (EEZ), which represents 138,000 km2. Regional and international cooperation is needed to promote the establishment of protection zones of migrations, breeding and nursery species that move throughout the Caribbean. Twinning have been undertaken with United States, the Netherlands Antilles and the Dominican Republic. They could establish an ecological corridor.

The Nature Reserve of Saint-Bartholomew is a representative service of the PTOM for the Agoa sanctuary. The Nature Reserve lists observations of whales, dolphins, killer whales, pilot whales, and sperm whales. These data are then relayed to researchers at the regional level. They want to know more about their migration and to estimate the number of individuals. It also participates in biannual monitoring of marine mammals organized by the sanctuary Agoa.
Agoa’s scientific surveys will allow us to better understand the marine mammals, including their movements along migratory routes. The goal is to sustainably manage their habitats, especially in monitoring human activities.
