Caribou Facts

Environmental Dangers Affecting Caribou

Located at 68 ° latitude, -141° longitude.

There has been a catastrophic decline in caribou on the Arctic islands of North America and they are now considered endangered.

  • The formation of ice layers that prevent the caribou from accessing food has been identified as the chief cause of the decline.
  • In northwestern North America, recent warming has led to a dramatic increase in the number of days of above freezing temperatures during the migration period for caribou.
  • Thawing and subsequent re-freezing of snow results in ice layers in the snowpack, which hinders the caribou's travel and makes it harder to forage for food.
