Germany is Europe's most populous nation. A land hewn by mighty rivers and cloaked in forest. In these wild spaces, nature is full of surprises. From the Bavarian mountains to the North Sea, over a third of the country is now protected. Huge Grey Seals battle to breed, Marmots and Squirrels flee aerial invaders, and elusive Lynx and Moose - once hunted out - re-assert their grip.
