Reduction and avoidance measures
Reduction in the disturbance of the Balearic shearwater during periods of internuptial presence
Objectives and methodology
The objective of the measure was to inform site personnel to enable the avoidance of shearwater rafts by personnel transfer vessels (CTV) during work at sea and to raise public awareness.
This measure targeted departures from Saint-Quay-Portrieux (initial port of the construction phase), because the impact study had highlighted that rafts of shearwaters were present between this port and the construction area at sea. However, the location of the port evolved and it was then located in Lézardrieux. Rafts of shearwaters are no longer found on shipping routes and the risk of encountering them is now negligible, thereby reducing the incidence identified in the impact study. The measure was therefore adapted to meet new needs.
The measure has a double scope:
Public information
Following prior collaborative work between Ailes Marines and local ornithological associations, an information and awareness leaflet was distributed to the public and those involved in recreational activities during local events. These documents will also be relayed by tourist offices, sailing schools and even certain maritime operators. Two annual awareness operations were also implemented from 2021 to 2023.
Raising awareness among CTV operators (Ailes Marinespersonnel transfer vessels)
Other actions particularly targeted ship personnel linked to the wind farm construction site. As such, CTV staff were made aware before the start of the project. Captains and members of the flight crew have been trained to recognize the species. In the event of detection of a raft, the captain of the ship will have the obligation to transmit the position of the Balearic Shearwaters encountered (so that the information circulates to allAiles Marinescrew), and to avoid said raft in order to limit their disturbance.
Location of actions
Awareness-raising operations will be organized in two coastal communities to the east and west of the bay of Saint-Brieuc.
