Out of the woods?

Emerging from a stand of trees in the Northwest Territories of Canada comes a wood bison, the larger of the two subspecies of American bison. There were once tens of thousands of wood bison roaming the chilly boreal forests and open meadows in north-west Canada and parts of the US state of Alaska. But by the early 1900s, these majestic animals were driven almost to extinction by hunting, disease and habitat loss.
