Site description Tso Morari in eastern Ladakh is the largest of the high altitude Trans-Himalayan lakes situated entirely within Indian territory. The lake formerly had an outlet to the south, but has now become landlocked, because of which the water is now brackish to saline. The lake is fed by streams and snowmelt from two major stream systems, which create extensive marshes when they enter the lake. The lake is frozen from November to April. Small islands near the north and south ends are important for breeding waterfowl. The lake is bounded by mountain ranges with peaks exceeding 6,500 m. On the north and east sides, the lake is bounded by the hills of the Tibetan cold desert. The western side is bordered by steeper peaks exceeding 5,500 m. The Pare Chu river, which originates about 40 km upstream of the lake, flows along the southern side. Between Tso Morari in the north, and the Pare Chu in the south, lies the Nuro Sumdo wetland, covering an area of about 2,000 ha (Mishra and Humbert-Droz 1998). There does not appear to be any vegetation in the deeper parts of the lake, but shallow areas have some Potamogeton. Various species of sedge and rushes grow in the marsh, notably Carex. Caragana and Astragalus spp. characterize the steppe vegetation. Juncus thomsonii and Leontopodium sp. are also found.
