CHANGCHUN, June 14 (Xinhua) -- Two photos of endangered wild Siberian tigers were recently taken in a forest in northeast China's Jilin Province, researchers announced on Thursday.
The photos were taken on April 4 on Changbai Mountain in Wangqing county in the Yanbian Korean autonomous prefecture, which borders Russia and the Democratic People's Republic of Korea.
Funded by the World Wildlife Fund (WWF), the Wangqing County Forestry Bureau has set up more than 100 automatic infrared cameras in the forest to capture images of rarely viewed animals.
According to the WWF, the cameras have captured many photos of Siberian tigers and Amur leopards in recent years.
Siberian tigers are one of the rarest species in the world. The total number of the population is about 500, concentrated in Russia, China's northeast and northern parts of the Korean Peninsula.
China has only about 20 wild Siberian tigers. They live in the regions of the Changbai mountains in Jilin Province and the Wanda mountains of Heilongjiang Province near China-Russia border.
The country launched a natural forest resource conservation program in 1998, specifying 17 regions, including the Changbai Mountain Natural Reserve, as targets for ecosystem protection.
