Only a few rivers in Europe are in their natural state. They need to be protected.
Either by various classical legal means (such as the EU’s Natura 2000, conservation areas, national parks etc.) or by the creation of other “voluntary” instruments o structures.
Another important element to attain the best possible protection of rivers is a network of all parties and campaigns along a river as well as a communication strategy which informs and motivates citizens and decision-makers to take action.
