Wild Caribou Welfare in a Changing Climate

Climate change is disrupting caribou migration timing, food availability, and predator interactions, creating new welfare challenges for these iconic Arctic species.

Key Facts

North American caribou populations have declined by over 50% since the 1990s
Rain-on-snow events lock lichen under ice, causing widespread starvation
Warming temperatures are shifting insect harassment seasons, disrupting migration
Wolf predation pressure increases when caribou are weakened by food shortage
Some herds travel over 5,000 kilometers annually - among the longest migrations of any land mammal

Welfare Considerations

Caribou welfare is deeply tied to ecological integrity. When climate disruption causes ice encasement of lichens, caribou face starvation - a prolonged and painful death, particularly severe for pregnant cows and calves. Biting insects drive caribou into exhausting flight behaviors to escape harassment. These stressors are compounding, with weakened animals more susceptible to predation and disease. Protecting large intact habitats and addressing climate change are the most impactful actions for caribou welfare.
