Eight Beavers Prevent Flooding in West London After 2023 Reintroduction

Summary
Paradise Fields in Ealing has gone flood-free for the first time in a decade after a family of five beavers was reintroduced there in 2023; the site now holds eight adults plus a new spring litter.
The beavers replaced a proposed concrete reservoir by building dams, ponds and canals that slow runoff and spread stormwater across the 24-acre wetland, protecting nearby streets and Greenford station.
The project has also turned a neglected urban patch into habitat for birds, bats, butterflies, fish and freshwater shrimp, with local residents embracing beaver watching and guided “safaris.”
Experts say such rewilding can also help with drought and wildfire resilience, but only where food, water, space and community support exist; poorly planned or illicit releases can damage farmland and infrastructure.
As London's beaver population grows, how will the city manage conflict between wildlife and urban life?
Are beavers the future of urban flood control, or a risky gamble with unforeseen costs?
How the Ealing Beaver Project Reduced Flooding and Boosted Biodiversity in Urban London
Overview
The Ealing Beaver Project, launched in October 2023, is a collaborative effort by groups like the London Wildlife Trust and Ealing Council to reintroduce beavers—a species absent from Ealing for centuries. Driven by the need for better flood management, community groups proposed bringing in beavers, whose natural dam-building helps regulate water flow and reduce flooding. The project has sparked strong enthusiasm from both the public and local officials, reflecting a shared commitment to making London 'one step wilder' and supporting biodiversity. This innovative approach highlights how nature-based solutions can address urban challenges and inspire community involvement.
