The largest single project of the compensation and replacement measures is the ecological upgrading of the Zuelowniederung. The area is located in southern Brandenburg between Mittenwalde, Dabendorf and Groß Machnow/Rangsdorf and consists of about 2,600 hectares of lowlands. The Berlin Airports entered into a cooperation with the Landschaftspflegeverein Mittelbrandenburg e.V. (former: Verein für Landschaftspflege und Umweltschutz Teltow-Fläming e.V.) in 2003.
The object is to upgrade the agriculturally oriented, open lowlands and by means of smaller partitions of the utilization and emphasis of the existing structures design the landscape in a more varied manner. The compensation measures should improve the living conditions for flora and fauna and therefore increase the quality of the Zuelowniederung.
