Here's why:
* Location: The Boreal Forest stretches across a vast band of the Northern Hemisphere, including large portions of Canada and Russia.
* Climate: It's characterized by long, cold winters and short, cool summers.
* Vegetation: Dominated by coniferous trees like spruce, fir, and pine.
* Wildlife: Supports a diverse range of wildlife including moose, elk, wolves, bears, and various bird species.
While other biomes might be present in smaller portions of both countries, the Boreal Forest is the most significant biome shared between Canada and Russia.
