Follow-up measures
Monitoring bats during the construction phase
Objectives and methodology
During the operational phase, 8 wind turbines were equipped with acoustic recording stations (ultrasound) in order to evaluate and characterize the activity of migrating bats in the park area.
This monitoring, among other things, aimed to provide information on the presence of the Nathusius Pipistrelle migrating in the offshore wind farm. The latter having been detected at the Grand Léjon lighthouse but never in the park area.
This monitoring also made it possible to provide information on whether the wind farm in operation constitutes a source of light attraction for bats.
To do this, 8 wind turbines were equipped with acoustic (ultrasound) recording stations. These stations are distributed around the outskirts of the wind farm (see Figure below).
Location of actions
Eight acoustic recording stations were distributed among the peripheral wind turbines within the park. Positions 50, 61, 47, 38, 12, 3, 4 and 25 were favored (see figure below).
Schedule and Status
Measurement finalized
The monitoring took place during bat migration periods, i.e. in spring and fall in 2021, 2022 and 2023.
