Follow-up measures
Monitoring of avifauna by maritime radar
Objectives and methodology
Monitoring of avifauna by maritime radar is carried out using an automated radar/camera system installed in the park. Vertical data provides information on flight height while horizontal data provides information on lateral trajectories/directions. These two pieces of information are important to see if the birds change their flight height, avoid the wind turbines laterally, enter directly into the park, and leave again.
The two main objectives are:
Continuously measure bird flows
Determine the average traffic rate and assess potential changes in seabird behavior due to the presence of the park: macro/meso/micro avoidance, height and direction of flight. In addition, this type of monitoring during the park's operating phase will also make it possible to measure the birds' habituation to the presence of the park.
Measuring the migratory flow
Passing through the installation site (in spring and autumn), in order to learn more about the importance of the passages in the bay of Saint-Brieuc
The system (location, type of radar, coverage, dual navigation/avifauna vocation, configuration, maintenance, etc.) is operational in the operating phase.
Location of actions
Two radars are installed within the park, one to the north on foundation no. 57, and the other to the south.

Schedule and Status
Measure implemented
This monitoring began when the park's wind turbines were commissioned and for a period of 2 years during the park's operating phase.
