In 2014, birdwatching ornithologists as part of ex-post monitoring found Montagu’s harrier nests at the wind farm; as a result, Polenergia launched an active protection programme for this rare species of the Accipitridae family. The nests were fenced in so that agricultural machinery would not threaten the nests during harvesting and other agrotechnical operations. The birds were also protected from predators by spreading certified scented repellent, which is completely safe for humans, animals and the environment. Observations showed that young Montagu’s harriers from subsequent broods (2014-2021) left the nest safely.
