Secrets of the Flooded Forest - Danube National Park (2010)
After beginning in Vienna, the Danube riverbank forests extend to the gates of Bratislava, linking the two capitals like a green ribbon, forming a unique wildlife habitat in the heart of Europe. A few years ago a 36 kilometer section was turned into a national park that now protects the last undeveloped stretch of the Danube River and also the last riparian zone of its size in Central Europe.
