Balkan dam projects could result in loss of one in 10 European fish species

Exclusive: Plans for a network of hydropower plants in three countries would cause 'chain reaction' for endangered species, report warns

Nearly one in 10 of Europe's fish species will be pushed to the brink of extinction by a constellation of hydropower plants planned in the western Balkans, new research has found.

Eleven endemic species would be wiped out, seven more would be critically endangered, four types of sturgeon would be devastated and the number of endangered species would double to 24, according to the University of Graz report.
