On April 23, 1999, the House of Representatives of the Croatian Parliament has brought a decision about proclamation of Nature Park Papuk. The important reason for proclaiming Nature Park Papuk is due to the preserved characteristics of live and still nature, typical for the central Slavonia. It is beyond the doubt that it is about the wide natural and partially cultivated area with emphasis on the esthetical, ecological, educational, cultural, historical, tourist and recreational values. The Park of Nature is first of all a scientific, cultural and educational institution, set up to preserve natural conditions and characteristics, and to introduce wide population with the laws of nature. Because of diversity and heterogeneousness of flora and fauna of this area, the adequate protection is required, whose basis must be first of all based on scientific cognitions. The proclamation of Nature Park Papuk would allow the more efficient protection of rare and endangered plants and animals.
