Site description Diyatra Closed Area in Bikaner is one of the most important sites for the Great Indian Bustard Ardeotis nigriceps in the Thar Desert (Rahmani 1986, 1997). In the early 1980s, there were 30-50 bustards in this area, but due to intensification of agriculture, overgrazing and poaching, the number has perhaps halved. The site used to be the hunting reserve of the Maharaja of Bikaner for Great Indian Bustard. The site is situated approximately 65 km southwest of Bikaner along the National Highway to Jaisalmer. Various departments of the Rajasthan Government have established pasture enclosures at various periods of time but most of them are neglected and over-run by livestock. If properly protected, these grassland enclosures would have provided undisturbed breeding areas to the Great Indian Bustard. However, now these enclosures are mainly used by Chinkara Gazella bennettii, and Nilgai Boselaphus tragocamelus, and rarely by the Great Indian Bustard. Important flora of Diyatra consists of Zizyphus rotundifolia, Capparis decidua, Calotropis procera, Prosopis cineraria, Calligonum sp., Leptadenia pyrotechnica and the grass Cenchrus biflorus (Satish K. Sharma pers. comm. 2003). The sandy zone, having low grasslands and scrub vegetation is dominated by Zizyphus rotundifolia and Capparis decidua.
