New study highlights positive beaver impact on rivers

by Angling Times |

A study has revealed that beaver dams can benefit water supply, improve water quality, and limit the impact of drought.

Researchers from the University of Aberdeen collected evidence from 120 beaver populations worldwide to review their impact on waterways. It’s the first time that evidence has been gathered on the management role that these animals – which have already been introduced to sites in England – play in ecosystems.

Josie Geris, who led the new study, said:

“Beaver dam building could help to address several important water management challenges. They trap sediment, which improves water quality, and may also limit the effect of drought.”

Angus Tree from NatureScot, added:

“The study backs up evidence we’ve gathered over the years and will help our work with stakeholders as we develop the best ways to live with, and benefit from, beavers.”
