With the purchase of areas in the Rheinauen near Bingen-Gaulsheim , NABU protects the quality of an important biotope. Some cropland, an apple orchard and a recreation area were acquired with the plan to turn the areas gradually into near-natural meadows or orchards.
NABU currently holds 58 hectares of land in Bingen and its surroundings. In the interest of conservation, NABU works with farmers and volunteers on the use and maintenance of the properties.
In addition, small bodies of water were established in the Rheinauen near Bingen, particularly within the scope of the “Upper Rhine lifeline” (German: “Lebensader Oberrhein”) project, which was concluded in September 2019. The project created new habitats for the tree frog. Maintenance is required because overly thick growth at the water’s edge, sedimentation of the water surfaces and other changes run counter to the goal of providing a permanent home for frogs. Although the silted up areas are sometimes attractive, they are not suitable as sunny breeding grounds for amphibians. For this reason, conservation work sometimes involves the use of saws and mowers.
