XINING, Aug. 1 (Xinhua) -- An ecological monitoring system in northwest China's Qinghai Province has spotted more than 300 Tibetan antelopes returning to their natural habitats after giving birth in the heart of the Hoh Xil National Nature Reserve from July 25 to 31, according to the provincial ecology and environment department.

Every year, pregnant Tibetan antelopes migrate to the heart of Hoh Xil between the end of May and early June to give birth and leave with their offspring around August.
Launched in 2016, the remote video observation system has been built with cameras set at 38 monitoring points across the province, including some in the Sanjiangyuan region, Qinghai Lake and the Qilian Mountains.
The monitoring point in Hoh Xil is near the Qinghai-Tibet Railway, which is an important spot along the migration route of Tibetan antelopes.
"It's difficult to observe the migration of Tibetan antelopes through wardens alone. This system can record videos around the clock without disrupting the animals," said Chen Liangbo, from the provincial ecology and environment department.
The real-time videos are transmitted to the database of the department about 1,100 km away, Chen said. "With the help of this 'ecological window,' researchers can remotely observe the ecological environment and wildlife in key areas of the province, and conduct further research and evaluation."
According to statistics from the reserve's management bureau, the number of Tibetan antelopes that migrate back to the area has been rising. A total of 4,860 Tibetan antelopes were spotted migrating last year, 338 more than in 2018.
