How beavers are protecting West London from flooding

To find a little wilderness in West London, take a left at the shopping mall and head under the highway. Near a McDonald's and within reach of the city's busy transport network, a family of beavers is reshaping a wetland and helping protect nearby streets and a Tube station from flooding.

Veterinarian and conservationist Dr. Sean McCormack, one of the driving forces behind the Ealing Beaver Project, puts the chances of spotting one during a recent visit at 90%.

But these animals were brought here to do more than draw an audience. They were offered a job.

"They had planned a lot of expensive engineering works to create reservoirs to hold more water," he said. "And we said beavers could do that at a fraction of the cost and maybe more effectively."

The beavers got to work, felling trees, gathering branches and building dams. By July this year, they had constructed seven dams and created three ponds that help retain water.

The project also reports that the dams have helped prevent flooding in Greenford Station's lobby and the surrounding residential area.

Beside a fallen tree, McCormack points out how a beaver chewed more deeply into one side of the trunk, bringing it down into the water.

For visitors joining a guided evening beaver safari, the attraction is often simpler: catching sight of an animal going about its business in an unexpected corner of the capital.

The breeding success has become another sign that the animals are settling in. The project reported that the parents, Willow and Woody, welcomed two more kits in 2026, their third consecutive year of breeding. McCormack has described their continued success as "nature's report card."

The lessons could reach beyond this patch of London: learning to live alongside beavers and harness their benefits could help communities facing the challenges of climate change, McCormack said.
