Local forestry administration said Wednesday that more wild Siberian tigers and leopards were spotted this year in northeast China's Jilin Province since an annual survey began in 2012.
Jilin Forestry Administration said it found 27 Siberian tigers and 42 Amur leopards.
Of the tigers and leopards spotted, young cubs made up about half of the population, according to the survey.
Experts from the forestry administration said four female tigers would reach their breeding age in a year or two.
Jiang Jinsong, chief tiger and leopard researcher at Jilin Forestry Administration, said more protection was required as the tigers and leopards breed faster.
