Résumé partiel
The Thar Desert of Rajasthan is situated in north-western part of India. It lies between 25°30’ N and 28°15’ N latitudes and 69°00’ E to 72°30’ E longitudes. Thar desert has unique biodiversity and with the aim to conserve desert biodiversity, one wildlife sanctuary namely “Desert National Park” (DNP) was established vide notification dated 4/8/80 having an area of 3162 sq. km across Jaisalmer and Barmer districts of Rajasthan. DNP was once home to 50% of Great Indian Bustard (GIB) population of whole country, which has now come down to just about 45 individuals. The Great Indian Bustard (Ardeotis nigriceps), endemic to the Indian subcontinent, was once widespread in the semi-arid open scrubland and grassland plains. It is the state bird of Rajasthan and is locally known as Godawan belonging to the family Otididae of order Gruiformes. The big variation in the estimate of GIB was mainly because in the past extensive study of this bird has not been carried out in Rajasthan. Since there is no detailed study in understanding GIB, habitat utilization so far been undertaken, therefore, the proposed study has provided valuable information on GIB’s requirement and developed appropriate conservation strategies to assess the GIB population and its distribution in and around DNP. The study was design to bring out a comprehensive status report of the occurrence of Great Indian Bustard (GIB) and its distribution, movement, patterns and threats on its population in Thar desert landscape of Rajasthan so as to suggest long-term managerial practices, in order to safeguard the surviving populations and to help increase the numbers wherever feasible.
