Europe’s freshwaters are in an alarming state. Water pollution, habitat destruction and the ongoing effects of climate change have caused significant biodiversity loss and ecological decline across the continent. There is a pressing need for major freshwater restoration projects which tackle these declines and bring rivers, streams, peatlands and wetlands back to life. MERLIN is a major European Union funded project which is investing millions of Euros to help mainstream freshwater restoration across the continent over the coming years. This podcast follows the MERLIN project in this journey. It offers a behind the scenes look at some of the continent’s most ambitious freshwater restoration projects carried out through cutting-edge aquatic science and conservation.
