Some communities, such as Umiujaq, are particularly at risk to be impacted by beaver expansion because of the geography, says Mikhaela Neelin, director of the Nunavik Hunting Fishing Trapping Association. Umiujaq is one of the communities located just north of the treeline — the edge of the habitat where trees are capable of growing. "In the tundra and a lot of regions, they're seeing beavers appear there for the first time," said Neelin, adding that the consequences are a mixed bag.
