Quick answer
Reindeers (Rangifer tarandus) typically live around 12–15 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway
Reindeers (Rangifer tarandus) typically live around 12–15 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Reindeer lifespan in the wild
Field and museum records place most reindeers near 12–15 years in the wild. That figure blends ages at death across regions, so treat it as a planning range. Body size (60–180 kg (130–400 lb); bulls larger) and risk lifestyle both shape the average.
What shortens reindeer lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever reindeers share landscapes with people.
What helps reindeers live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Reindeer life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing reindeers in the field.
Indigenous herding
Sámi, Nenets, and other Arctic peoples have herded domestic reindeer for centuries, following migrations and relying on meat, hides, and transport. Wild caribou remain vital subsistence resources for Alaska Native communities.
Climate vulnerability
Listed Vulnerable, reindeer and caribou face rain-on-snow events that ice over food, increased parasitic flies in warmer summers, and industrial disturbance of migration routes from mining and roads in the Arctic.

Reindeers eat lichens, grasses, leaves, and mushrooms, with seasonal and regional variation in Arctic tundra, boreal forest, and mountain plateaus.
Where do reindeers live?
They are associated with Arctic tundra, boreal forest, and mountain plateaus. Local presence depends on food, cover, and human land use.
