Monitoring of the marine biocenoses of the Nature Reserve of Saint-Barthélemy


On March 15 and 16, 2018, CREOCEAN coordinated and carried out the monitoring of the marine biocenoses of the Nature Reserve of Saint-Barthélemy, in collaboration with the Nature Reserves of Saint-Barthélemy, Saint-Martin and Petite Terre, within the framework of the "Reserves Network". This annual monitoring, initially planned for September-October 2017, had to be canceled following the passage of Hurricane Irma on the Northern Islands in early September.

Six months later, divers were able to collect data on the two coral reef monitoring stations (on and off reserve) and on a seagrass monitoring station. A new probe for continuous measurement of water temperature has been immersed, in order to make the link with the observation of signs of coral bleaching during the critical period.

The evolution of the health status of communities has been monitored since 2007 on these stations, the date of establishment of the monitoring network. This monitoring also makes it possible to train the staff of the nature reserves to the protocols and to reinforce the principle of "companionship" and exchanges (network of competences) between the different teams.
