Koch 1926 Very valuable stands of rare tree species, such as the white and black poplar (Populus alba and Populus nigraj and grey alder (Alnus incana^) reach their full developement here due to favourable and only slightly affected hydrological conditions. It is thanks to these conditions that some fine examples of the formation and slow developement ofriver islands -sandbanks and various degrees ofsoil and vegetation genesis - are found here. Such cases are very rare in Europe today. Cultures of Euro-American poplars, small white willows and locust-trees grow in area of 170 ha. After the end ofrotation period their further growth need not to be supported, but the developement of natura! stands, primarily with succession, should be ensured. The studied standsplay a very important role in maintaining the biological diversity of this area, preserving the gene fund of rare but important tree species (white and black poplar andgrey alder), and providing the medium of scientific research and education of riparian forest management. Therefore, the protection of this part of "Slatina Podravina Forests", provided by the Ministry of Agriculture and Forestry and by forestrv experts in the public enterprise "Croatian Forests", is fully justified. This isyet another confirmation that the Croatian forestry science has adopted aproper view ofthe importance of protection and future of valuable regions in the Republic ofCroatia. Our research is a positive contribution to evaluating and presenting natural facilities. Similar steps and studies should be conducted tofbrm a basis for proclaiming various protected categories by the State Administration for Nature and Environment Conservation. Šumarski list br. 7-8.
