Luftbilder machen Klimawandel sichtbar

Früherkennung von Pflanzenausbreitung in Gewässern

(PresseBox) (München, )
Durch die Folgen der Klimaerwärmung wandern unerwünschte Wasserpflanzen in heimische Gewässer ein. Auch bekannte Urlaubsregionen wie der Starnberger See sind betroffen, weshalb eine gezielte Überwachung der Wasserflächen nötig ist. Doch ist das bisherige Verfahren für regelmäßige Überwachung teuer - Forscher der Technischen Universität München (TUM) entwickelten jetzt eine schnellere und kostengünstigere Methode.

Aus einem Besuch am Badesee kann schnell eine unangenehme Angelegenheit werden - wenn man Bekanntschaft mit glitschigen Wasserpflanzen macht. Zu diesen zählen auch Elodea nuttallii und Najas marina, besser bekannt als Schmalblättrige Wasserpest und Großes Nixenkraut. Beide breiten sich seit einigen Jahren rasant in heimischen Gewässern aus.
