XINING, February 1 (Xinhuanet) -- The number of birds on the Qinghai-Tibet Plateau, known as the roof of the world, decreases at a startling speed, threatening ecological balance in the region.
There are 370 kinds of birds on the Qinghai-Tibet Plateau, of which, 30 are under top government protection.
A recent research by Li Laixing, a research fellow with the Northwest Institute of Plateau Biology under the Chinese Academy of Sciences, showed the types of birds in the region are roughly same as before. But the amount of birds, especially rare species, has decreased sharply.
The number of bird of prey such as eagle reduced rapidly. The black-neck crane, a worldwide endangered wildlife species, is a rare bird that can only be seen in the remote areas of Qinghai, Yunnan, Sichuan, Guizhou provinces and the Tibet Autonomous Region. Due to the shrinkage of wetland as a result of expanded areas by human beings, the flock of the black-neck crane witnessed a considerable drop.
Owing to decrease of birds, rat run rampant in some pastoral areas. The biological chain on the Qinghai-Tibet Plateau will be damaged, Li said. Enditem
