Site description Pangong Tso is a long, narrow, brackish lake spanning the Indian/ Chinese border, in a valley in the upper drainage basin of the Indus river, at the east end of the Karakoram Range. Only the westernmost one-third of the lake lies in Indian territory. It is a chain of four interconnecting lakes, formed by natural damming of the valley. Five rivers fed by perennial springs and snowmelt flow into the Indian portion of the lake. The runoff from the west end of the lake flows northwest into the Shyok river, a tributary of the Indus. There are some brackish to saline marshes near the western end, with adjacent wet meadows. The lake has been suggested as a Ramsar site due to its biological, cultural and geological values (Chatterjee et al. 2002). It is the largest and most brackish wetland in the cold desert ecosystem of the Trans-Himalaya. A fossil freshwater mollusc Lymnea auricularia was discovered in ancient lacustrine clay deposits above the present level of lake, providing evidence that earlier it was a freshwater lake (Sharma 2000). Due to its extreme salinity, Pangong Tso does not have any vegetation in the deeper parts, but at the margins and marshy areas, typical, steppe vegetation is seen. Sedges and grasses are found towards the northern and eastern sides. The surrounding plateau and hills support low thorn scrub and perennial herbs.
