Site description Sonkhaliya is one of the few sites which provides shelter to the Great Indian Bustard (Rahmani & Manakadan 1983; Rahmani 1987). During the few surveys done in the latter half of 1980s, the population of this bird was estimated to be c. 1,500-2,000 for the whole country, with Rajasthan holding more than half (Rahmani 1986, 1987). Sonkhaliya held a population of more than 80 bustards (Rahmani and Manakadan 1988). It is one of the preferred Bustard areas as it is more or less plain with crop fields and highly degraded scrub forest. The main natural flora of the site consists of species of Prosopis, Acacia, Capparis. Cultivated crops are also present.
