A colony of beavers reintroduced to an area of west London has helped prevent a railway station from flooding, according to the project behind their return.

The Ealing Beaver Project says, since the mammals moved in, Greenford station, downstream from the animals’ wetland home at Paradise Fields, no longer floods after heavy rain.

The beavers slow the flow of water during downpours and create wetlands that hold it back, easing pressure on the drainage system further downstream.
