Caribou migration, Alaska and Canada

Caribou migration from British Columbia in the west to Newfoundland in the east and from the US border to Ellesmere Island north of the Arctic circle.

The number of caribou involved in our thought to be around 2.4 million split into eight large migratory herds. These herds move from the tundra in the far north to the sparsely tread coniferous forest in the south. The length of the migration from north to south can be as much as 500 miles.

As well as the caribou, there are a wide range of predators that hunts the caribou along their route including wolves black and grizzly bears links coyote and golden eagles.

The caribou can cover as much as 50 miles in a day.
