Image data captured in a recent survey show that all 10 counties and one district in Nagchu, Tibet autonomous region, are home to rare species, including snow leopards and other animals, China News Service reported.

Since December, the city's forestry and grassland bureau and the Shanshui Conservation Center placed more than 140 infrared cameras. More than 100 images showing active snow leopards were captured.

Located in the vast northern prairie of Tibet, Nagchu lies between the Nyanchen Thanglha and Gangdise mountain ranges. The city is dominated by an alpine meadow and grassland ecosystem. Its eastern counties have some forest.

"Other species discovered in this survey include large carnivores, such as the wolf, jackal, brown bear, black bear and lynx," Mao Shiping, an official from the city's forestry and grassland bureau, was quoted as saying.

"Large carnivores rely strongly on adequate herbivores for their survival and reproduction," Mao added.
