Białowieża Forest is a vast forest area lying partly in Poland and partly in Belarus. The centrepiece of the forest is Białowieża National Park, along with the town of Białowieża. What distinguishes Białowieża Forest is its unique flora and fauna, many species of plants and animals are found only in that area, a significant number of which are protected and endangered. About 60 species of mammals live there, the most famous of which is, of course, the bison. The forest is also a kingdom of deer, elks, roe deer, wild boar, grey wolves or Eurasian lynx. Many species of birds also live there, with woodpeckers at the forefront. However, the forest is primarily famous for its primeval forests, which are very rare anymore. These are the last natural forests in the European lowlands. The recognizable symbol of Białowieża National Park is the bison. The largest herd of these animals in Poland and one of the largest in Europe currently lives there. Białowieża Forest is listed as a World Heritage Site by UNESCO. Its territory is divided into four zones. Zone one, the Białowieża National Park, is a place left entirely to the action of nature, where man is not allowed to interfere in any way. In the next two zones, limited human interference is possible, such as mushrooms picking or hunting certain animal species. In the last zone, conservation activities are allowed, among other things, to preserve natural animal habitats.
