Protecting rivers – healthy, dynamic and free-flowing Protecting free flow – the river‘s essential property and its ability to provide connectivity (in all dimensions) Protecting fluvial morphodynamics – the river‘s ability to constantly renew itself and shape its bed, banks and floodplains Protecting freshwater life – the river‘s ecosystem health, representing a mosaic of aquatic and terrestrial habitats and corridors across the land Titel Protecting the pathways rivers create, and allowing the river to renew itself – this is what river conservation is all about.

These sites should rather be the nucleus for a network of free-flowing rivers and streams with high ecological value that should be expanded through the decommissioning and removal of ecologically harmful infrastructure.

Prospects for a European network of protected rivers - healthy, dynamic and free-flowing: The EU Biodiversity Strategy provides new prospects for the vision of a European network of strictly protected rivers. This river conservation policy needs to aim at both protecting and restoring the key properties of rivers: Free flow, sediment dynamics, and connectivity in all dimensions. Rivers and floodplains need to be recognized as biodiversity hotspots: In order to gain a better understanding and achieve better management, freshwater ecosystems should be regarded as a third realm next (to marine and terrestrial). In light of the sharp decline of freshwater life, defending dynamic and free-flowing rivers against infrastructure projects including inland navigation projects (such as E40 Waterway or along the Oder) is a key challenge for biodiversity policies in the EU and globally. Living rivers depend on the energy hydropower is aiming to extract from them: As shown by a recent study on freshwater fishes in the Mediterranean Basin, hydropower is a key threat to freshwater biodiversity through imposing barriers and degradation of river and stream habitats. The European Environmental Bureau (EEB) along with other European NGOs is advocating a stop for new hydropower projects in the EU, as their environmental damage outweighs potential energy gains from electricity generation. Legal protection schemes for free-flowing rivers can find inspiration from existing examples: Examples for effective strict legal protection of free-flowing rivers against barriers and dams can be found in Slovenia (Soca River), Finland, Sweden, Spain. A Vjosa Wild River National Park as recently announced for Albania could spark a new way of protecting dynamic river landscapes. An inspiration from the US is the Wild and Scenic Rivers Act. All over the world, initiatives for legal protection ofTitel free-flowing rivers are connecting. Session 2: The Dam Removal Challenge Restoring free-flowing rivers combines with protecting the last wild ones: Dam removal is real - the removal of barriers is already happening, and the EU Biodiversity Strategy goal of restoring 25.000km of rivers to a free- flowing condition offers great opportunities for reconnecting fragmented habitats and re-establish connectivity throughout river systems. Prioritization for removal projects to gain maximum ecological benefit is starting to be carried out; funding for barrier removals is increasingly available from EU funds. Biodiversity objectives need to be addressed in the River Basin Management Plans under the WFD: Priorities for removing fish migration obstacles and other aspects of protecting of aquatic biodiversity need to be integrated into the current drafts of the River Basin Management plans under the Water Framework Directive. Protecting the pathways rivers create, and allowing the river to renew itself – this is what river conservation is all about Legal Protection Schemes for Free-Flowing Rivers in Europe Overview report commissioned by TNC prepared by Tobias Schäfer, Living Rivers Foundation, Berlin December 2019 Key findings: 1.
