Arctic fox

Loss of its tundra habitat is the biggest threat to the Arctic fox. Climate change is allowing new plants to colonise the area - changing tundra into boreal forest.

The red fox, which preys on the Arctic fox and competes with it for food and shelter, is moving northwards as the tundra becomes more productive.

Climate change is also altering the habitat for prey species, such as lemmings and voles, causing their decline and significantly affecting Arctic fox populations.
