The Éolien en Mer SIG initiated its first study in 2021.

The project involved The project involved multi-year monitoring of five natural gull nesting sites. The aim is to show the trends in the number of nests and the production of young, particularly in relation to the future construction of the Dieppe Le Tréport offshore wind farm.

From one year to the next, monitoring of the birds in these colonies should reveal whether they are staying on already occupied sites, whether they are dispersing or abandoning the sites and whether they are moving to new breeding sites.
