The Joint Danube Survey 2001 was carried out by the ICPDR and is the most homogenous analysis of the water quality and the ecological status of the Danube River. Over 140 chemical and biological parameters were analysed and over 40.000 laboratory results were generated.
Plants & Animals
The habitats created by the Danube and its tributaries host a unique mix of species. But many habitats are degraded by man-made changes to the river profile and width, water depth and flow velocity following the construction of dams, weirs and canals. Many migratory fish including sturgeon species and the Danube Salmon are endangered or close to extinction by being disconnected from their spawning grounds and habitats or by being over-exploited.
Ecosystems
A river does not end at its bank. The Danube and its tributaries form many diverse riverine habitats, including intricate networks of water bodies, creeks and channels, floodplain forests, water meadows, lakes, gravel islands, sandy banks and the unique delta habitats by the shores of the Black Sea.
