1Le Danube
Des montagnes de la Forêt-Noire à la ville frontalière de Passau, où il devient autrichien, le Danube change bien souvent de visage. Après avoir traversé des forêts d'épicéas, il plonge sur plusieurs kilomètres dans des enfilades de grottes souterraines ; à Weltenburg, il creuse la percée du Danube, une spectaculaire gorge au coeur d'un massif calcaire, avant de s'élargir dans les plaines de loess de la Basse-Bavière. Au fil du parcours, on rencontre des troglodytes, des hérons cendrés, des faucons pèlerins, des milans royaux et des cincles plongeurs
2La Lusace
En Lusace, «pays des mille lacs» situé à la frontière polonaise et défiguré par l'exploitation prolongée du lignite, la nature reprend peu à peu ses droits.
3Der Stechlin – Im Reich der klaren Seen (allemand)
Blue lakes surrounded by forest, lovely bays, wild solitude: in the north of Brandenburg there are lakes whose clarity is reminiscent of crystals. More than 100 of them are in the Stechlin-Ruppiner Land nature park. Above all the Stechlin east of Rheinsberg. It is 69 meters deep, particularly clear and one of the best-researched lakes. Sunbeams play on the backs of silver perch many meters below the surface. In the thicket of riparian vegetation, pike lurk in wait for the right moment to strike at lightning speed. When the water warms up in spring, several male pike will court a female. At his side, they animate the chosen one to give up eggs, scenes that have never been filmed like this before. Large, partly swampy forests surround the Stechlin and shield it from of modern agriculture. Slurry and fertilizers hardly get into the lake. The forest not only protects the lake, one of the fastest birds in the world has recently started breeding here again: the peregrine falcon.
4Berlin (allemand)
A fascinating parallel world between people, skyscrapers and multi-lane roads: millions of wild animals such as raccoons, foxes, bats, squirrels and beavers make their home in the green metropolis. There is at least one pair of birds for every resident of the capital, nowhere else are there so many sparrows and nightingales. Roland Gockel and Rosie Koch watched the animals change with the seasons.
