Beavers migrate into the Arctic as warming climate reshapes the landscape
By
Grace van Deelen
Summary
As climate change warms the Arctic, beavers are migrating northward, building dams that create new ponds and accelerate permafrost thaw. Their expansion is documented as far as the Arctic Ocean, altering water flows and creating challenges for Indigenous communities — including disrupted transportation routes and potential waterborne disease risks. The article highlights the lack of historical baseline data on this expansion and notes that tree ring analysis is helping researchers understand the timeline of beaver colonization in the Arctic.
