The Bialowieza Forest, a nature site on the UNESCO list, is the oldest forest in Europe; very little human intervention has taken place over the millennia. Located in north-east Poland and continuing over the border with Belorussia, it is the last natural forest of primeval character in the European Lowland Area. The young and old flora and fauna coexist in their unique environment. The forest is a home to hundreds of species of plants, fungi, moss, lichen as well as more than eight thousand invertebrate species, about 120 species of birds and 52 of mammals. Among them there are bison, wolves, bears, elk and boars. See http://whc.unesco.org/en/list/33
