Location: 33’50’N, 78’35’E;
on the Chinese border, 100 km ESE of Leh, Ladakh, Jammu & Kashmir
Area: 65,000 ha (about one-third in India, the remainder
in the People’s Republic of China)
Altitude: 4218 m
Biogeographical province: 2.38.12
Wetland type: 12,16
Description of site: Pangong Tso is a long, narrow,
brackishwater lake spanning the Indian/Chinese border, in a high mountain
valley in the upper drainage basin of the Indus river, at the east end of
the Karakoram Range. Only the westernmost third of the lake lies in Indian
territory. The lake is actually a chain of four interconnecting water bodies
and is probably of very recent origin, having been formed by natural damming
of the valley. Five rivers, fed by perennial springs and snow-melt, flow into
the Indian portion of the lake; the outlet at the west end 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
Climatic conditions: Arid, high plateau (Tibetan)
climate, characterised by marked differences between sun and shade, and night
and day temperatures. The average annual rainfall is 76 mm, and the temperature
range, -40°C to 20°C
Principal vegetation: Brackish to saline marshes
and alpine meadows at the west end of the lake. The lake itself is reported
to be devoid of macro-vegetation. Surrounding hillsides support low, thorn
scrub and perennial herbs
Land tenure: The lake and most of the surrounding areas are
state-owned (Jammu & Kashmir)
Conservation measures taken: The entire lake is protected
in a reserve, and all shooting of wildlife is strictly prohibited
Conservation measures proposed: The State Government intends
to declare an area of 400,000 ha in eastern Ladakh as a High Altitude Cold
Desert National Park. The existing Pangong Reserve would be incorporated within
this National Park
Land use: Local people graze their yaks and horses
on the marshes and meadows, and harvest the grasses for fodder
Disturbances and threats: The current level of grazing already exceeds the carrying capacity of the land, and is resulting in soil erosion. Domestic livestock cause some disturbance to nesting birds
Economic and social values: The marshes provide important
grazing land for the local people. The region has considerable potential for
scientific research and tourism although, at present, access to the area is
restricted. The lake itself has a considerable modifying effect on the local
micro-climate
Fauna: An important breeding area for a variety
of waterfowl, including Tadorna ferruginea. Anser indicus occurs in significant
numbers on migration and may breed. The surrounding hills support a rich assemblage
of Himalayan and Tibetan wildlife, including the wild ass (Equus hemionus)
Special floral values: None known
Research and facilities: Some research has been carried out
on the breeding ecology of Grus nigricollis
