The primeval forest of Białowieża used to be the hunting domain of the medieval Polish kings and later on of the Russian Tsars. The forest was well managed and protected, making this the last area where wisents were to be found in the wild. In 1932 the forest became a National Park and in 1979 it was declared a Unesco World Heritage site. In the '90s the Belarusian part of the forest was added. On the Polish side as well as on the Belarusian side are zoological gardens where the animals are kept that once were native in the forest or once again native nowadays, such as this red deer. After the moose, red deer are the second largest deer-species in Europe. They are found in Western and Central Europe, from Spain to the south of Scandinavia. In the Netherlands red deer are to be found in several National Parks.
