Free Rivers

Free Rivers

Free-flowing rivers are vital for the functioning and ecological connectivity of freshwater ecosystems. Dams, dykes, reservoires, navigation and irrigation systems are altering the flows of rivers and fragmenting them. Among these barriers in Europe, it is estimated that at least 100.000 are obsolete. The highest pressure is put on freshwater species: migratory freshwwater fish in Europe have already declined by 93% compared to 1970.

Freeing rivers from old barriers creates the enabling conditions for ecological processes, which ultimately bring to a healthy and resilient freshwater ecosystem.

Knowing where and which those barriers are is the first step to remove them. The scale of river fragmentation across Europe is almost unknown because of lack of data and because barriers are managed by different entities.

With the AMBER Barrier Tracker App you can record barriers into a database just with your smartphone. You just need to take a picture, add the location, the description and the height of the barrier. Through this app people have collected data on more than ten thousands barriers. This helps identifying where rewilding and restoration are needed, as well as to keep inventories updated.

By just going around with your phone, you can contribute to accelerate river rewilding!

There are around 100.000 barriers in European rivers and streams that are not being used. They are old, and not serving the purposes they were intended for anymore – but they are fragmenting rivers and, among others, preventing movement of fish. Having those barrier in place has became costly, with obligations of mantainance and all the missing ecosystem services from a free-flowing river.

We have set up a small task force of young people that want to do some desk research in order to map specifically small obsolete barriers in their area, with the goal of eventually facilitate their removal.
