The grey snub-nosed monkey, an endangered species only found in the southwest China`s Guizhou Province, has quadrupled to around 800 over the past 20 years, said a local official in charge of protection for the animal.
The monkey, the rarest among the three species of golden monkeys in China`s Sichuan, Yunnan, Gansu and Hubei provinces, mainly lives in the Fanjingshan National Nature Reserve in northeast Guizhou.
"We have acquired through research detailed data concerning the number, clans, distribution and existence of the animal," said Yang Yeqin, director of the reserve, who participated in a decade-long field investigation on the species.
The findings of the systematic research provide us with valuable first-hand data for better preserving and protecting this animal, he said.
Groups of the snub-nosed animal were not found by Chinese scientists until early 1980s, when they estimated the number of the animal was around 200.
