Résumé :	Since 2000 the Rhin-Havelluch region has developed into one of the most significant inland stopover sites for crane migration on the west European flyway. In recent years, at least 70,000 cranes were gathering at the roost in Linum during the peak of migration in October. Mean-while, numbers were going down at the second important roost in Nauen due to water shortage and losses of feeding grounds associated with wind energy plants and recurrent anthropogenic disturbances. Surveys of marked cranes in the Rhin-Havelluch region have shown that the proportion of birds from Norway/Sweden was relatively low compared to the proportion of the East Baltic region (Finland and Estonia). To meet the demands of nature conservation precisely due to the fact of continuously growing numbers of cranes and tourists in the region, NGOs and governmental conservation centres are dedicated to maintain crane stopover sites in the Rhin-Havelluch. Beside this, it is the objective to reach the maximum possible protection level for the sustainability of regional water balances as well as the establishment of a full-time and well qualified regional management for crane conservation.
