Résumé :	The European population of the Common Crane Grits grits has increased significantly during the last 30 years because of specific conservation measures, habitat restoration, and changes in agriculture. The Common Crane bred in Bavaria, Southern Germany, until about 1890 but due to intensive wetland drainage and peat harvesting it ultimately disappeared as a breeding bird. During the last 10 years, pairs of Common Cranes have sporadically been observed, and in the North-eastern part of Bavaria (Oberpfalz) a total of six successfully raised young have been confirmed since 2006. During migration through Bavaria, cranes stop over for between a few days and several weeks During the last 20 years these passage numbers have increased significantly. The Common Crane needs wetlands for breeding, but also as nocturnal roost sites during migration and on the wintering grounds. Where it finds undisturbed habitats, the Common Crane is able to breed successfully. Because conservation measures for the Common Crane also protect wetlands and their associated biodiversity, the crane is a good flagship-species.
