The Danube River is the most international river on the planet - its course runs across or forms a part of the borders of several countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Ukraine, and four capitals: Vienna, Bratislava, Budapest and Belgrade. Formed over a period of more than 10, 000 years, the DanubeDelta continues to grow due to the 67 million tons of alluvia deposited every year by the Danube River.
The DanubeDeltaBiosphereReserve has the third largest biodiversity in the world (over 5, 500 flora and fauna species), exceeded only by the Great Barrier Reef in Australia and the Galapagos Archipelago in Ecuador.
The DanubeDelta is home to over 60% of the worlds population of pygmy cormorants (phalacrocorax pygmeus), 50% of red-breasted geese (branta ruficollis) and the largest number of white pelicans (pelecanus onocrotalus) and Dalmatian pelicans (pelecanus crispus) in Europe.
