Bhotiyas are people of presumed Tibetan heritage that live along the Indo-Tibetan border in the upper reaches of the Great Himalayas, at elevations ranging from 6,500 feet (2,000 m) to 13,000 feet (4,000 m). In Uttarakhand, they inhabit seven river valleys, three in the Garhwal division (Jadh, Mana and Niti) and four in the Kumaon division (Johar, Darma, Byans and Chaudans). Their main traditional occupation used to be Indo-Tibetan trade, with limited amounts of agriculture and pastoralism. The customary Indo-Tibetan trade drastically stopped following the 1962 Sino-Indian war, and was resumed in the early 1990s under state-regulated mechanisms. These days, medicinal and aromatic plant collection is a major livelihood among this group, alongside by out-migration for education and jobs. Tra
