National parks are the fullest and most effective form of nature preservation.
They include mainly ecosystems that are of natural origin or close to it, especially valuable because of scientific, didactic, social, cultural and educational considerations. The basic goal of national parks is the protection of rich natural values, availing them for scientific studies and preservation of the unique flora and fauna for the future generations. National parks in Poland have a 70 year history. The majority of the national parks are composed predominantly of forest. The rest of the area is covered by dunes, peat bogs, marshes, rocks and terrain above the upper limit of the forest.
