"Within weeks, the beavers dammed up the creek, creating a pond that holds water and stops it from spilling into the city. They also diverted the creek's flow into smaller tributaries, creating a wetland that better absorbs heavy rainfall.Not only has the local Tube station stopped flooding, but the beavers have also coaxed back other species.The beavers have also allowed the city to scrap expensive plans to dig a reservoir and levee."https://www.npr.org/2026/05/21/nx-s1-5738979/beavers-britain-climate-change-flooding
