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.
