Compensation measures
Eradication of American Mink on the Tregor Islands - pink granite coast
Objectives and methodology
The operations are part of an overall project for the ecological restoration of the island to the profile of breeding seabird colonies. In fact, the invasive American Mink has spread on Tomé Island, predating the eggs of the nesting colonies and preventing any nesting. This is dramatic for the islet and could eventually threaten the colonies of the Seven Islands if this species gets there.
This compensation measure is part of the multi-partner programme, set up under the name "Trégor-Gestion-Vison", run by the Fédération départementale des chasseurs des Côtes d'Armor, the Conservatoire du Littoral, the LPO, the commune of Perros-Guirec, Lannion Trégor Communauté and Ailes Marines.
It has three main objectives:
Eradicate
The presence of the American Mink on Tome Island.
Check
The absence of the American Mink on the Sept-Îles National Nature Reserve.
Capture
Several individuals on the coast between Perros-Guirec and Penvénan for genetic analysis.
Location of actions
The monitoring is carried out on the whole Tome Island, when tidal conditions allow it.
Planning and Status
Measure put in place
This compensatory measure has been in place since 2017, as follows:
- Trapping - Eradication: Annual action for 5 years
- Three-yearly monitoring after the eradication period and for the life of the project
