Common Crane Management In Germany -Monitoring, Protection, And Scientific Work, Hartwig Prange
Proceedings of the North American Crane Workshop
About 200,000 common cranes (Grus grus) from northern, middle, and northeastern parts of Europe are migrating on the West-European route. In the northeast part of Germany 160,000 cranes stop over simultaneously during migration. This number has increased since the early 1980´s by 3-fold. About 60 sites with from 200 to 50,000 cranes are systematically observed from August to December by local expert groups. The overnight roosts are in ponds, swamps, and lakes, actively flooded meadows, and brown coal mines as well as in shallow backwaters of the Baltic Sea. They have been used year after year. More than …

Reduction Of Crop Depredations By Cranes At Daursky State Biosphere Reserve, Siberia, Oleg A. Goroshko, John E. Cornely, Stephen H. Bouffard
Proceedings of the North American Crane Workshop
The Daursky State Biosphere Reserve (SBR) in southern Siberia includes the Torey Lakes, the largest lakes in the Trans-Baikal region. The Torey Lakes support tens of thousands of breeding waterbirds and about a million waterbirds during migration. Peak numbers of birds staging during fall coincide with grain harvest. Crop fields around the Torey Lakes attract 50,000 to 70,000 waterbirds, primarily cranes with lesser numbers of waterfowl, causing significant crop damage in fields near Daursky SBR. Investigations of the problem have been ongoing since 1992. Field consultation by Cornely and Bouffard in 2001 resulted in recommendations to reduce depredations. The consultation …
