Since the 1990s, the Bremen nature conservation authority has been planning a biotope on the 25-hectare area on the Kreuzdeich to compensate for large-scale sealing, especially for the residential areas of Borgfeld-West and Borgfeld-Ost. The basis for this is B-Plan 2253, Part B.
A floodplain biotope and a dyked water retention basin (polder) are to be created.
The aim is to transform the area into a floodplain landscape, including a shallow water lake with fluctuating water levels typical of the floodplain, reed beds and willow bushes.
The plans for this are the installation of a wall, the excavation of a standing body of water with a connection to the Wümme and an adjustable water level, the dynamic development of woody stands, the conversion of arable land into permanent grassland and the creation of a path connection around the planned Kreuzdeich polder
In 2021 the cross dike was closed and the excavators finally moved in. The path is now accessible again and there is a lot to see.
The shallow water lake has already been excavated and a 31m long steel pipe has been laid as a connection to the Wümme. The Wallung is also taking on clearer features. A hiking trail is also planned here later.
If you come by more often, you can observe the changes and progress and let your imagination run wild as to what it will look like here later.
