Location : Est and west of
Chushul village, near the Chinese border, 120 km ESE of Leh, Ladakh, Jammu
& Kashmir
Area: 11,000 ha
Altitude: 4385m
Biogeographical province: 2.38.12
Wetland type: 15,16
Description of site: A complex of shallow ponds,
marshes, and wet meadows in a broad, sandy valley to the east (10000 ha) and
west (1,000 ha) of Chushul, some 15 km south of Pangong Tso. The ponds and
marshes are created by springs and streams flowing down into the valley from
the Ladakh range to the southwest. Some streams terminate on the sandy plains
in stagnant pools, which become saline as they evaporate; others carry sufficient
water to flow into Pangong Tso and ultimately the Indus river. Small freshwater
marshes have formed where these streams coalesce or where they reach a body
of standing water. Most of the ponds and marshes are frozen from November
to March; they reach their maximum extent during June and July through increased
melt water run-off from the high peaks, and shrink again thereafter. The ponds
average only one or two metres in depth
Climatic conditions: Arid Tibetan climate, characterised
by marked differences between sun and shade, and night and day temperatures.
Summer temperatures range from 0° C to 30° C, winter temperatures from - 5°
C to - 30°C. Humidity is low, and there is very little precipitation in the
form of rain or snow (average annual precipitation about 75 mm)
Principal vegetation: Species of Hydrilla, Myriophyllum,
and Potamogeton in the ponds, and Carex sp., other sedges, and grasses in
the marshes. The surrounding and steppe is dominated by Caragana sp.
Land tenure: The wetlands are state-owned (Government of
Jammu & Kashmir); surrounding areas are under both government and private
ownership
Conservation measures taken: Shooting is strictly prohibited
throughout the area
Conservation measures proposed: It has been proposed that
the marshes be declared a wildlife sanctuary where grazing and fishing would
be allowed only in certain areas. These constraints would also help in conserving
water resources in the.area. The wetland lies, within the boundaries of the
proposed High Altitude Cold Desert National Park (400,000 ha) in eastern Ladakh
Land use: There is a certain amount of fishing. Yaks, sheep,
horses, and goats graze in the marshes and wet meadows
Disturbances and threats: Human activity in the area is increasing.
The associated increase in livestock grazing in and around the wetland areas
is posing a threat to the vegetation and causing soil erosion. Yaks regularly
wade out into the shallow waters and in so doing disturb the nesting birds.
Washing activities in streams near Chushul cause some contamination, and permanent
human settlement increases predation of the eggs and nestlings of waterfowl
by ravens (Corvus corax). Sporadic incidences of hunting by armed forces personnel
have been reported
Economic and social values: Freshwater marshes are rare in
Ladakh; they are thus a focal point for human beings as well as wildlife,
particularly during spring and summer
Fauna: An important breeding area for several species
of waterfowl, notably Podiceps cristatus, Tadorna ferruginea, Charadrius mongolus,
Tringa totanus, and Sterna hirundo. One pair of black-necked cranes (Grus
nigricollis) breeds, usually on a small freshwater lake in the west, and Anser
indicus may still breed. A number of Tibetan specialities occur on the surrounding
dry plains, including Tibetan partridge (Perdix hodgsoniae), Tibetan sandgrouse
(Syrrhaptes tibetanus), and wild ass (Equus hemionus)
Special floral values: No information
Research and facilities: Several studies have been carried
out on the ecology of Grus nigricollis, and P. Gole and the Bombay Natural
History Society have made collections of plants, aquatic animals, and some
bird species
