Site description Tso Lhamo Plateau, Lashar, Sebu La and Yumesamdong complex is typical cold desert on Tibetan Plateau and trans-Himalyan facies, with high snow mountains and glaciers, lakes and geothermal springs and vast valleys with grasses, sedges, cushionoid vegetation, lichens and associated fauna. In this Reserve Forest on the international border with Tibet (China), heavy military deployment has caused a network of roads on the plateau with military establishment mostly near glacial lakes of Gyam Tsona and Tso Lhamo. The area has a short growing season from May to October with peak in July-August when most of the birds breed. This eco-region has not yet been included in the protected area network of the State and is perhaps the most threatened as it contains many endangered species (protected under Schedules I and II of the Indian Wildlife (Protection) Act 1972, such as the Tibetan Wild Ass or Kiang Equus kiang, Nayan Ovis ammon and Black-necked Crane Grus nigricollis. This IBA seeks to link the Tso Lhamo Plateau with the Lashar, Sebu La Yumesamdong section, reaching southwards to touch the Sino-Himalayan Temperate Forests below Yumesamdong and around Thangu in North Sikkim.
