Follow-up measures
Monitoring bats during the operational phase
Objectives and methodology
In the operational phase, 8 wind turbines are equipped with acoustic recording stations (ultrasound) in order to evaluate and characterize the activity of migrating bats in the park area.
This monitoring aims, among other things, 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 provides information on whether the wind farm in operation constitutes a source of light attraction for bats.
To do this, 8 wind turbines are 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 are distributed among the peripheral wind turbines within the park. Positions 50, 61, 47, 38, 12, 3, 4 and 25 are currently preferred (see figure below).
Schedule and Status
Measure implemented
This monitoring constitutes the continuation of the bat monitoring in the construction phase. It also takes place during bat migration periods, in spring and fall. It began with the commissioning of the wind turbines in the park and for a period of 3 years during the operating phase of the park, i.e. in 2024, 2025 and 2026.
