Beaver-engineered dam in the Czech Republic
In early 2025, a family of beavers constructed a series of dams that restored a wetland in the Brdy Protected Landscape Area, Czech Republic. Their activity coincided with a government project initially proposed in 2018 to address environmental degradation in the region. The government's project was delayed as a result of bureaucratic and financial issues. The beaver-built dams provided ecological benefits, including improved water quality, enhanced biodiversity, and better water retention, while also saving the Czech government approximately US$1.2 million.
