'Serbia, which lies at the heart of the Balkans, is called “little Europe,” a name that does full justice to the land and its extremely varied landscapes and nature. Serbia’s breathtakingly grandiose landscapes and unique animal world are at the forefront of this journey to the most beautiful and wildest areas of the Balkan peninsula. This is presumably the sole HD documentary about nature in Serbia, Europe’s hot spot for diversity of species. Highlights are the rare shots of wild jackals and black storks.'
Fortunately, someone has uploaded the documentary to youtube. Those who are unable to understand the German narration, can take a look at the English language trailer.
Another German production available on youtube and worth watching, documents Balkan nature and wildlife as if it could have been the inspiration for J. R. R. Tolkien's Middle Earth.
