Monitoring of chiropterans in the exploitation phase

Objectives and methodology

In the operational phase, 8 wind turbines will be equipped with acoustic recording stations (ultrasounds) in order to evaluate and characterize the activity of migrating chiropterans in the wind farm area.

One of the objectives of this monitoring is to provide information on the presence of the migrating Nathusius Pipistrelle in the offshore wind farm. The latter having been detected at the Grand Léjon lighthouse but never in the area of the wind farm.

This monitoring will also provide information on whether the operating wind farm is a source of light attraction for chiropterans.

For this purpose, 8 wind turbines will be equipped with acoustic (ultrasound) recording stations. These stations are distributed around the periphery of the wind farm (see figure below).

Location of actions

Eight acoustic recording stations will be distributed on the peripheral wind turbines within the park. Positions 50, 61, 47, 38, 12, 3, 4 and 25 are currently preferred (see figure below).

Measure under development

This monitoring will be the continuation of the chiropterical monitoring during the construction phase. It will also take place during bat migration periods, in the spring and fall. It will begin at the commissioning of the wind turbines of the wind farm and will last for 3 years during the operation phase of the wind farm, i.e. in 2024, 2025 and 2026.
