Sažetak
The Kopački Rit Nature Park is located in northeastern Croatia, in the floodplain formed by the confluence of the Danube and the Drava Rivers. It was proclaimed as Nature Park in 1999, at total surface of 231 km2. In July 2012, it was included in the UNESCO Transboundary Biosphere Reserve Mura-Drava- Danube. The diversity of flora, vegetation, and distribution of land, aquatic and wetland habitats are depending on frequency, intensity and duration of floods. Recent vascular flora comprises 512 taxa, of which 156 (31%) are macrophytes. Based on records collected during the multiannual field surveys, the presence and distribution of aquatic and wetland plant communities in the Kopački Rit Nature Park had been analysed. Prolonged dry season and low Danube water level stimulate growth of the amphibious communities from the alliance Nanocyperion on muddy or sandy bottoms. Such situation was during the extremely dry summer in 2003, when channels and most of the standing water bodies dried out, and during autumn in 2012 and 2015. During spring and summer 2010, ecological conditions were optimal for the shallow marsh vegetation from the order Oenenthalia aquaticae. Flooding and prolonged duration of high Danube water levels in the warm summer period makes the optimal conditions for growth of freely floating, rooted, and floating-leaved aquatic vegetation from the orders Lemnetalia and Potamogetonetalia. It was highly pronounced in summer 2011, 2013 and 2016. Since the water outflow was rather slow, high air and water temperature stimulated abundant growth of the aquatic vegetation on water surface.
