Ladakh. A detailed survey of the<br />

status of this species was initiated.<br />

As a pilot study, data was collected<br />

on the status and breeding pattern<br />

of the species at selected wetlands.<br />

The study was enlarged into a more<br />

organized scientifi c one because of<br />

the importance of the species as<br />

an indicator of the health of wetland<br />

ecosystems. <strong>WWF</strong>-<strong>India</strong> and<br />

Department of Wildlife Protection,<br />

Jammu and Kashmir conducted an<br />

intensive study of the population<br />

of <strong>Black</strong>-<strong>necked</strong> <strong>Crane</strong> at all the<br />

potential wetland sites in Ladakh<br />

following standard methodology.<br />

Study Area<br />

The study area is situated in<br />

Changthang region of Ladakh<br />

in <strong>India</strong>.<br />

The Himalayas extend for over<br />

2500 km along the northern<br />

frontier of <strong>India</strong> in one giant sweep<br />

from the Nanga Parbat massif in<br />

the west to the Namche Barwa<br />

in the east. North of this high<br />

Tent of a nomadic family in the study area<br />

range lies the Tibetan plateau that<br />

was mostly formed as a result of<br />

tectonic upliftment of the Tethys<br />

Sea in the Miocene and Pliocene<br />

period (Wadia, 1966). The region is<br />

generally referred to as the Trans-<br />

Himalaya and is a cold desert. The<br />

vegetation in the region is sparse<br />

and productivity peaks only in the<br />

short summer season. This harsh<br />

environment is thus home to only<br />

highly adaptable fl ora and fauna.<br />

The Tibetan plateau region is very<br />

vast and within <strong>India</strong> extends for<br />

1,84,823 sq km in the states of<br />

Jammu and Kashmir, Himachal<br />

Pradesh with small portions<br />

extending into Sikkim and<br />

Uttaranchal mountains.<br />

Ladakh is part of the Trans-<br />

Himalayas of the Tibetan Plateau.<br />

This area, a cold desert, is<br />

interspersed with high altitude<br />

plains, green patches of marshy<br />

meadows (with Carex and Caragana<br />

often interspersing these), willow<br />

plantations near habitations and<br />

sparse vegetation. The terrain is<br />

extremely rugged with high cliffs and<br />

exposed rocks.<br />

The present study was conducted<br />

in eastern Ladakh commonly<br />

known as Changthang and is<br />

characterized by arctic conditions,<br />

wind-swept desert and barren hills.<br />

The Changthang region lies at 4000<br />

m and above. The soil is sandy or<br />

sandy loam. Borax deposits in the<br />

dried marshy areas and around<br />

wetlands is a common feature.<br />

Strong and unpredictable winds<br />

make the area highly inhospitable.<br />

The single most characteristic<br />

feature of the region is the dryness<br />

(Sapru and Kachrroo 1976). In<br />

summer the temperature ranges<br />

from 0º C to 30º C and the winter<br />

temperature is between –10º C<br />

to – 40º C (Mishra and Humbert-<br />

Droz 1998).<br />

This region has numerous wetlands<br />

- brackish as well as freshwater.<br />

Apart from their hydrological<br />

importance, the wetlands are<br />
