Location: 100 km SSE of Leh,
Ladakh, Jammu & Kashmir
Area: c.20,000 ha
Altitude: 4,530 m
Biogeographical province: 2.38.12
Wetland type: 12,16
Description of site: In a very remote and sparsely
populated area, the Tso Kar Basin, a land locked basin of a former large freshwater
lake (now in a state of dessication) has contracted into two principal water
bodies: Startsapuk Tso, a brackish lake of about 300 ha in the south, and
Tso Kar itself, a hypersaline lake of 2200 ha. Startsapuk Tso, frozen over
from October to March, is fed by perennial springs and snow-melt and becomes
almost fresh during the mid-summer period of maximum run-off; it reaches its
maximum depth of 2-3 m in July and August and overflows northwards into Tso
Kar. The marshes around the larger lake contain areas with extensive deposits
of natron, borax, and other salts, and there are sulphurous hot-water geysers
nearby. The basin is surrounded on all sides by peaks rising to over 7000
m
Climatic conditions: Arid Tibetan climate, characterised
by marked differences between sun and shade, and night and day temperatures.
There is very little precipitation in the form of min or snow within the basin.
Summer temperatures range from 0°C to 32°C, winter temperatures from -5°C
to as low as -40°C
Principal vegetation: In the fresher parts of the
basin, the pools have an aquatic vegetation composed of Potamogeton sp., and
Hydrilla sp. These plants die back in winter to form floating mats of weed
in spring. The adjacent freshwater marshes and damp meadows support a mixture
of Carex sp. and Ranunculus sp. The arid steppe vegetation of surrounding
areas is dominated by species of Astragalus and Caragana
Land tenure: The wetlands and surrounding areas are state-owned,
under the control of the Revenue Department (Jammu & Kashmir)
Conservation measures taken: The wetlands have been afforded
some protection as a wildlife reserve, and the shooting of wildlife is strictly
prohibited
Conservation measures proposed: It has been proposed that
the status of the reserve be upgraded to that of Sanctuary with a proper management
plan incorporating habitat improvement measures for breeding waterfowl. The
basin lies within the boundaries of the proposed High Altitude National Park
(400,000 ha) in eastern Ladakh
Land use: Seasonal grazing by domestic livestock, mainly
yaks and horses, and cutting of aquatic vegetation. The commercial exploitation
of salt deposits was found to be unfeasible, though Rupshu-Kharnak nomads
still use them at a subsistence level Possible changes in land use and proposed
development projects: The construction of a road through the two Tso Kar wetlands
has been proposed
Disturbances and threats: Intensification of grazing, particularly
by yaks, is a direct threat. The construction of a road through the two wetlands
may increase human activity, disturbing the fauna
Economic and social values: A small Buddhist monastery near
the lake attracts pilgrims. The basin’s potential for tourism would be realised
if it were opened up, and this is a distinct possibility
Fauna: The basin is a major breeding
area for Podiceps cristatus (over 30 pairs on the southern lake), barheaded
goose, brahminy duck, brown-headed gull (a large breeding colony), and common
tern. One pair of black-necked cranes (Grus nigricollis) breeds in the area.
As many as 100 Tibetan Sandgrouse (Syrrhaptes tibetanus) come to drink each
morning at the shallow pool in the meadows to the west of Tso Kar. Wild ass
(Equus hemionus) and Tibetan gazelles (Gazella sp) forage in the marshes and
meadows, and Canis lupus and Vulpes sp occur in the surrounding - hills. Marmot
(Marmots bobak) are commonly found around the lakes
Special floral values: None known
Research and facilities: Some studies have been made on the
breeding birds, particularly barheaded goose and black-necked crane
