Beavers are being credited with solving chronic flooding issues in the Ealing borough of West London. For three years, areas near Greenford station have remained flood-free thanks to an extensive network of dams built by the industrious creatures. These dams create wetlands which naturally retain excess rainwater during heavy storms, effectively mitigating flood risk. The beaver’s return to the region represents a successful example of natural intervention addressing environmental challenges. Beyond flood control, the beaver activity has also revitalized local ecosystems, attracting a greater diversity of wildlife. This initiative demonstrates the potential of working *with* nature to provide cost-effective and sustainable solutions. It highlights a free and effective answer to previously annual problems.
