Hot Dam: Why beavers are Britain’s new climate heroes

Beavers are returning to Britain after a 400-year absence, serving as natural engineers to mitigate flooding and restore biodiversity. Once hunted to extinction for their fur and secretions, these semi-aquatic rodents now play a critical role in climate adaptation by building dams that create wetlands, effectively managing water retention in both rural and urban environments. While their presence offers a cost-effective alternative to expensive human-made infrastructure, it sparks controversy among farmers concerned about crop damage and riverbank erosion. Despite these conflicts, beavers act as a keystone species, fostering the return of diverse wildlife, including rare butterflies and various bird species. Scientists continue to monitor these populations, balancing the ecological benefits of rewilding with the practical challenges of coexistence in modern landscapes.
