Images show health of river valley in Tibet

"Since 2018, Tibetan herders have been trained as ecological monitors, and nearly 55 infrared cameras have been placed at strategic points covering more than 1,000 square kilometers in the Nujiang River Valley," said Zhao Xiang, director of the center, adding the ecosystem in these areas is healthy.

"The captured images show that rare species — including the snow leopard, common leopard, Tibetan brown bear, Eurasian lynx, wolf and dhole have been stable inhabitants," Zhao said.
