The Donau-Auen National Park protects the largest contiguous wetlands environment in Central Europe. In this region – situated between Vienna and Bratislava – the free-flowing stretches of the Danube have been preserved. The wetlands along the river are the most pristine and ecologically significant of the Central European Danube.

The diverse habitats of these wetlands – despite the Donau-Auen National Park's relatively modest total area of 9,300 hectares at present – make the biodiversity found here absolutely unique in all of Central Europe.

Over 800 vascular plant species and more than 30 mammalian, 100 breeding bird, eight reptilian and 13 amphibian species – not to mention around 60 fish species – live on the National Park grounds. If one takes the abundance of terrestrial and aquatic insects as well as invertebrates into account, the number of individual species rises to over 5,000.

It is our aim to make available a comprehensive and continually expanding lexicon of flora and fauna native to the Donau-Auen National Park; visit the "Flora" and "Fauna" sections of this website for more information.

Other parts of the website offer comprehensive information about the Danube River – the lifeblood of the National Park – as well as habitats, conservation measures, and important projects.
