There are two subspcies of Great Bustards in China. Otis tarda tarda. a rare resident of inKashi region. Tianshan Mountains and Turpan region in Xinjiang Uygur Autonomous Region innorth-- western China.The other is O. t. dybowskii found in north--eastern China.In summer of 199: our team has surveyed Temeeji at Zhalait Qi and nearby the Horqin YouyiQianqi and Beidagang at Zhenlai County. In an area of about 840sq km were found 150 GreatBustards. The average density was 0. 18 birds/sq. km.Reasons for the decline of Great Bustard: l)Increase in human population and land reclamation. 2)Excess animal husbandry in the grassland. The breeding habitats of Great Bustards in transformingto unfavorable habitats. 3)Eggs and nests of Great Bustards may be trampled by sheep and cattle4）4)Collection of eggs by’ local people and foaching. 5)Medical herb collection and grass cutting. Suchactivities exposed the breeding sites of the Great Bustards.Conservation measures recommended: l)Establish nature in their main breeding and winteringareas. 2)Promotion of’ conservation education. Conservation should also be taught at schools. 3)Regulaie the increase of immigration in habitats impeortant to great Bustards. 4)Strengthening of lawenforcement to stop poaching and control of firearms. 5)Stop land reclamation at the Great Bustardssites and try to recover some degraded grasslands. 6)International cooperation on the conservationand research.
