Dam Good Work

Returning wild beavers to their former habitats can help clean up polluted waterways and restore the natural environment for other wildlife, according to a new study by the University of Exeter.

The British scientists worked with the Devon Wildlife Trust to find that the toothy animals can remove large amounts of sediment, as well as nitrogen and phosphorus pollution created by agriculture, from the water that flows through the ponds they create with their dams.

All that material can create problems for wildlife and, without the beavers, needs to be removed at processing plants before the water can be used by humans.
