European rivers are full. Of fish? No, barriers. Over 1 million barriers are blocking our rivers and as shown in the map above more and more are discovered each day.
The above map is a result of the AMBER project which aims to map all barriers in European rivers. The map has two tabs, one is called “App” this is all the data collected by Citizen Scientists using the “Barrier Tracker“, a smartphone app designed to give all citizens a chance to track barriers in their river.
The other tab is called “Atlas”, this is a collection of official data gathered by scientists from the AMBER project and is frequently updated. That is why some countries might not show any barriers yet.
