Both quantities and species of wild animals in Nagqu prefecture of northern Tibet Autonomous Region(TAR) have gained a remarkable increase year by year thanks to the effective preservation efforts.

"With several years' protection of rare wild species, the quantity of Tibetan antelopes now increase to 120,000, twice as many as the reported 60,000 in 2002, and the figure of wild Tibetan donkey rises from 50,000 to 80,000," said Tan Yongshou, a administrative official of Nagqu prefecture.

Tibetan antelope, under China's first grade protection, was recognized as endangered species by the World Conservation Union and the United States Fish and Wildlife Service.

Sitting in the hinterland of the Qinghai-Tibet Plateau, Nagqu boasts more than 600 million mu (about 40 million hektares) of natural grassland and four million hektares natural wetlands, with the largest protected area on the earth - Changtang State Nature Reserve. Among the 486 kinds of wild animals inhabited in this region, 40 are now under the state or regional level of preservation and protection.

The delightful achievements also attribute to the establishment of the nature reserves. To date, 17 nature reserves have been built, with two under national preservation level, covering a total area of 236,000 square meters which takes up 56.2 percent of the territory of TAR.
