Tsaatan (reindeer people), Mongolia. - Stockfoto

Tsaatan (reindeer people) are the last reindeer herders who survived for thousands of years inhabiting the remotest subarctic taiga, moving between 5 and 10 times a year. Presently, only 44 families remain, their presence threatened by the dwindling number of their domesticated reindeer. The Tsaatan rely on the animal for most, if not all, of their basic needs: milk, which is also used to make cheese; antlers, which they use to make tools; and first and foremost, transport. They do not use the reindeer for meat. This makes the indigenous group unique among reindeer-herding communities.
