The Bialowieza National Park is one of the oldest national parks in Poland and probably the most known and most valuable one although other parks have a long and glorious tradition as well.
A team of scientists and nature enthusiasts declared the part of the Bialowieza Forest situated between Narewka i Hwoźna rivers Forest District "Rezerwat". That was the best preserved part of the Bialowieza Primeval Forest and it was decided it should be a subject to the highest form of protection. That fragment of the forest was the beginning of the Bialowieza National Park is still the most valuable part of it and is strictly protected. The Bialowieza Forest is the last well -preserved fragment of primeval European lowland deciduous forest. Its value and the natural character is the result of long-lasting protection implemented by the emperors of Eastern Europe: princes of Lithuania, kings of Poland and Tsars of Russia. The biological diversity of the Forest is exceptional and is based on richness of fungi, plants and animals which are often the relicts of the primeval forests.
