Bhotiyas of Uttarakhand in the context of Zhang-Zhung language

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). They follow Hinduism with Buddhism and traditionally speak West Himalayish languages related to the old Zhangzhung language. Their main traditional occupation used to be Indo-Tibetan trade, with limited amounts of agriculture and pastoralism. The Indo-Tibetan trade came to a halt following the 1962 Sino-Indian war, and resumed only in the early 1990s under state-regulated mechanisms. Their major livelihood at present is the collection of medicinal and aromatic plants in the Himalayas. Many have also migrated out of their traditional habitats to towns at lower elevations. The traditional transhumance and pastoralism have also drastically reduced.
