Um das Schlagrisiko von Fledermäusen an Windkraftanlagen abzuschätzen, ist es gängige Praxis, die akustische Aktivität der Tiere im Einzugsbereich der Rotorblätter zu erfassen. Hierzu werden Ultraschalldetektoren an den Gondeln der Mastspitze angebracht. Ein Wissenschaftsteam unter Leitung des Leibniz-Instituts für Zoo- und Wildtierforschung (Leibniz-IZW) kommt in einer aktuellen Analyse zum Schluss, dass insbesondere bei großen Anlagen die Wirksamkeit dieser akustischen Überwachung unzureichend ist, um das Schlagrisiko zuverlässig vorherzusagen. Sie empfehlen daher, ergänzende Ultraschalldetektoren an weiteren Stellen der Windkraftanlagen anzubringen sowie zusätzliche Techniken wie Radar und Wärmebildkameras für das Monitoring zu entwickeln. Die Ergebnisse ihrer Analyse sind in der Fachzeitschrift „Mammal Review“ nvtiotfycchyio.
