A safe route for wolves and moose travelling between the forests and nature reserves of Poland and Germany is to be created by the Brandenburg rural development and environment department. The 200 km wildlife corridor is to include specially built bridges over autobahns near Berlin to allow the safe passage of the migrating mammals, whose numbers have burgeoned since the fall of the Berlin Wall in 1989 and the subsequent population decline in eastern Germany. Wolves and moose, the largest member of the deer family, have been protected by law since German reunification and there are now around 40 wolves living in the forests of Brandenburg and Saxony.
