There’s more than one barrier per mile on average in Europe’s rivers, which chokes off life in these critical arteries. But public awareness is sparking calls to take out small dams, weirs, and ramps.
Rivers in Europe are more fragmented—meaning their natural flows are interrupted by man-made barriers—than any other continent’s rivers, new research shows.
In a four-year study spanning 36 European countries, scientists surveyed almost 1,700 miles of river by foot—and found at least 1.2 million obstacles preventing European rivers from flowing freely. That’s more than one barrier for every mile of river (or 0.74 barriers per kilometer).
