Vegetation of the Special Zoological Reserve of Kopački Rit

This paper presents the results of several years' surveys on the vegetation of the Special Zoological Reserve of Kopacki Rit. Over this large floodplain of the Danube and Drava rivers prevail different types of hygro- and hydrophytic communities. Some of them are relatively constant, having persisted in this Reserve for many years with a relatively constant area. Some other communities, particularly aquatic ones, appear periodically, and their area is directly influenced by surface water area and duration of the flood.
