"The monitoring data of wildlife migrating along Qinghai-Tibet Railway shows that the using rate of wildlife passageway has raised from 56.6% in 2004 to 100% now." said Yang Haijiang, director of the Planning and Statistics Department of Qinghai-Tibet Railway Company. Since the Qinghai-Tibet Railway is open to traffic, the migration pattern of rare wild animals including Tibetan antelope is almost not affected.

Qinghai-Tibet Railway spans across many national nature reserves such as Hoh Xil, Sanjiangyuan and Qiangtang. With an average altitude of 4000 meters above sea level, it is the main habitat of Tibetan antelopes that are world's rare species. In addition, there are many other rare wildlife including wild yak and Kiang.  

To minimize the ecological effect on wildlife habitat made by the Qinghai-Tibet Railway, depending on migration patterns, 33 wildlife passageways with a total length of 58 kilometers are built along the Golmud-Lhasa section.

At the same time, continuous monitoring is made on rare wildlife along the Qinghai-Tibet Railway. Related data shows the using rate of wildlife passageway is improving year on year. The increasing number of Tibetan antelopes shows that the wildlife's foraging, migration and multiply are not affected by the Qinghai-Tibet Railway.

In 2004, 1660 Tibetan antelopes were recorded migrating across the wildlife passageway, while in 2011, the number exceeded 5000. Distributed in alpine and desert areas in Tibet, Qinghai and Xinjiang, Tibetan antelopes are first class national protected animals. Statistics show the number of Tibetan antelopes has recovered to nearly 20, 0000 at present.
