The river Werra has its source in the Thüringer Schiefergebirge (Slate Mountain Range). It then winds between the Thuringian Forest and the Rhön mountains before it joins the river Fulda to make up the river Weser near the town of Hannoversch Münden.
The Werra itself and the system of many smaller rivers and creeks shape the Thuringian Landscape. To conserve the biodiversity and the habitats of animals and plants, BUND and NABU set up the project „Living Werra“.
In many places the Werra suffers from the saline wastewater of the former potash industry, embankments and shoreline stabilisation. Where are no natural riverbanks and flooding areas or sandbanks anymore, animals have lost their original spawning grounds and their breeding areas.
