Beavers have begun to expand their territory into Canada’s western Arctic, with a recent study reconstructing the timeline of their initial activity in the region. The study indicates that these ecosystem engineers first became active in the area sometime around 2008.
Historically, North American beavers, scientifically known as Castor canadensis, have been primarily associated with boreal and temperate waterways. Their presence has traditionally been linked to these specific environmental conditions.
However, recent observations show an increasing trend of beavers moving northward into the Arctic tundra. This northward migration represents a significant shift in their established range, impacting the Arctic ecosystem.
