In 2016, conservationists put the bends back into a Lake District river straightened 200 years earlier; within months, Atlantic salmon were spawning there for the first time in centuries

Centuries after people forced a Cumbrian river into a straight, artificial channel, nature has reclaimed its original course in the Lake District, bringing endangered wild fish back to historic spawning grounds almost immediately. In the summer of 2016, conservationists restored a 1.1-kilometre stretch of Swindale Beck near Haweswater by putting its natural bends back into … Read more

Söderåsen national park (Image Credit: Canva) Much of Sweden’s Söderåsen plateau was once far more open than the dense woodland visitors see today. A 2025 study published in The Holocene found that the landscape became much more open during the 18th and 19th centuries as grazing intensified, with grazed heathland developing on parts of the … Read more

In 2001, Denmark began restoring 19 km of the straightened River Skjern by turning it into 26 km of winding river. Researchers later found that some of the habitats lost during decades of river engineering could take centuries to return.
