The operations are part of a global ecological restoration project for the island with the profile of nesting seabird colonies. Indeed, the American Mink, an invasive species, has spread to the Tomé islet, predating the eggs of the nesting colonies and preventing any nesting. This is dramatic for the islet and could ultimately threaten the colonies of the Seven Islands if this species reached that point.
This measure, implemented since 2012, aims to limit predation on seabird clutches by crows tending to specialize on the Common Guillemot and the Black-legged Kittiwake. The Syndicat Mixte Grand Site Cap d'Erquy Cap Fréhel, an experienced operator of this practice, has been implementing this compensation measure on behalf of Ailes Marines since 2019.
This measure has allowed an increase in the number of nesting pairs. All high-stakes species reached a historic record number for Cap Fréhel over the period monitored.
The objective of this measure is to strengthen the peace and quiet of marine mammals in the Normandy Breton Gulf during the construction phase of the wind farm off the coast of Saint-Brieuc Bay.
Several meetings were organized with state services and marine mammal experts during 2019 and early 2020.
