Wild reindeer and caribou populations face welfare challenges from climate change that creates dangerous ice layers over grazing habitat and disrupts traditional migration routes.
Wild reindeer welfare is intimately connected to Arctic climate stability. Rain-on-snow events create famine conditions where thousands of animals starve slowly over weeks when lichen becomes inaccessible. Pregnant females in nutritional deficit deliver calves with low survival rates. Industrial development fragments traditional migration routes, creating barriers that strand animals between wintering and calving grounds. Climate action is the most important intervention for wild reindeer welfare.
