Beavers' dams and ponds can turn a stream corridor into a net annual carbon sink, drawing in more carbon than it released over the course of a year, a new study finds.
The finding has big implications for the reintroduction of Eurasian beavers (Castor fiber) across Europe after centuries of being hunted to near extinction. If similar patterns hold elsewhere, the animals could help to mitigate climate change by sequestering the greenhouse gas without any costly infrastructure.
