In order to permanently preserve the quality of habitat for bird species resident to the Weidmoos, it was essential to alter the post-extraction state of the site, so that an open landscape with numerous bodies of water and moist areas would remain. The most important measure to ensure the long-term conservation of the Weidmoos as an open landscape – and therefore as a valuable bird habitat – is the so-called “re-waterlogging” of the site. Rainwater can be retained in the area by closing drainage channels and through the construction of dams, all of which will lead to the creation of new ponds. The Weidmoos itself had the ideal building material for these dams:.
