The Management Board of the Iroise Marine Park has decided to ban jet skiing in sensitive areas of the Iroise that are home to a coastal group of bottlenose dolphins(Tursiops truncatus). This solution was proposed to the French government to protect the home range of this species, which is highly sensitive to disturbance and noise pollution caused by this type of craft.

The activity is now regulated by a decree issued by the Atlantic Maritime Prefect and prohibited in the home range of coastal bottlenose dolphins. This decision has since been challenged before the competent courts, and the scientific arguments gathered by the Marine Natural Park teams are being used to defend this measure, which is essential for the protection of cetaceans.
