Act no. 114/1992 Coll. on Nature and Landscape Protection defines national parks as extensive territories that are unique according to a national or international standard, a considerable part of which are natural ecosystems or ecosystems little affected by human activities, where plants, animals and inanimate nature are of an exceptional scientific and educational significance. All utilisation of national parks must be subsidiary to the preservation and improvement of the natural conditions, and must be in conformity with the scientific and educational aims sought after in the proclamation of national parks. There are four national parks in the Czech Republic at present, covering 1.52% of the country’s surface area.
