The Rhin- und Havelluch (with biggest concentrations near Linum and Nauen) is the most important staging site for cranes in Germany. The region is mainly used by cranes of east European origin (Poland, Baltic States, and Finland). Numbers until 2007 are only covering the Rhinluch with the roost site Linum.
