Résumé :	Data on resting Common Cranes in northern Thuringia (Germany) during autumn migration are briefly summarised for the last decades. Currently, two stable roosting sites are existing. In the Helme reservoir south of the Harz Mountains the number of resting cranes has considerably increased since the beginning of the 1990s and reached a scale of more than 20.000, twice for a short time even up to 40.000 birds. For the flood control basin Straussfurt a resting tradition with clearly rising trend is obvious since 1997. There also several thousand birds are observed annually. TO decrease damages to agriculture caused by cranes a diversion feeding is conducted since 1996 in the area around Helme reservoir. The high disturbance pressure by leisure activities, the unfavourable water regime as well as the food damages by cranes require a concept for protection under participation of all stakeholders.
