sea level is situated on the northwest bank of this lake and is claimed to be the world's highest year-round inhabited village. The Tsokar Lake lies in the Rupshu valley and it is the famous Salt Lake of Ladakh. The Changtang Wildlife Sanctuary has natural grasslands and a wide variety of more than 200 species of wild plants grow in the higher pastures of this area, most of which is edible for animals. Hamlets Changtang hamlets were established when many Tibetan nomads, mostly from western Tibet, fled and settled down in the adjoining places of Ladakh. There are more than 3,500 Tibetan refugees residing in the Changtang region who depend primarily on livestock, with agriculture being their secondary occupation. These nomads were organized into the Tibetan refugee settlements in 1977 by the Central Tibetan Administration, Dharamsala, with help from Government of India and the state government at nine different places: Nyoma, Kagshung, Goyul, Hanley, Sumdho, Samedh, Karnag, Chushul and Churmur. These settlements are scattered across the high-altitude plateau with an average elevation of . The temperature in the region varies from in winter and up to a maximum of in summer. Large areas of Changtang are semi-arid, with very little vegetation growth in the whole region. Agricultural lands and pastures are confined to limited areas along the riverbanks (Yatoo et al., 2014). The average snowfall is less than occurring usually during the months of December, January and February. Unusual and excess snowfall as happened in March 2012, can be fatal to the livestock of the nomads. Sometimes, goats and sheep cannot get access to the grass for grazing for period up to 15 days. This constitutes the most critical part of the year for the nomads (Yatoo et al., 2014). Education in Ladakh is looked after entirely by the SOS Tibetan Children Village, one of the non-profit institutions providing education to the Tibetan children. There is a facility for crèche to tenth standard. Most of students attend day school, but there are also boarding facilities for very poor students and those from nomadic camps. Almost all children get a chance to go to school, and the general education level of the children is fairly good. The settlements have one modern allopathic hospital and one Tibetan medical and Astro clinic. There is also a bird sanctuary.
