“Kopački Rit” Nature Park was established in 1967 and covers the vast floodplain area between the confluence of the Danube and the Drava River. It hosts the largest and best preserved willow forests in the Danube Basin. This area is flooded up to three months per year. Nearly 300 bird species have been recorded so far, including 50 breeding pairs of white-tailed eagle. It is the second most important fish spawning area after the Danube Delta. Planned channelling of the Danube and Drava in the area would severely impact this core area of the TBR MDD.
