The study found that the Northeast can support the survival of more than 300 Siberian tigers in the future

The reporter learned from Northeast Forestry University on the 27th that the research team of the Feline Research Center of the National Forestry and Grassland Administration led by Jiang Guangshun of Northeast Forestry University and the research team from the World Wildlife Society, the World Wildlife Fund, the University of California, the Heilongjiang Institute of Wildlife and other domestic Experts from foreign institutions collaborated on the latest research results on the population dynamics and conservation potential of China's wild Siberian tigers entitled "Integrated Assessment Calls for the Establishment of a Sustainable Siberian Tiger Metapopulation in Northeast Asia" in the journal Biological Conservation on the 23rd
.
The results show that Northeast China is already home to at least 55 wild Siberian tigers and will be able to support the survival of more than 300 Siberian tigers in the future

The research lasted for 6 years, covering all the habitat landscape patches of the Siberian tigers in China, with a total of about 2,400 automatic cameras deployed, and a total monitoring time of about 2.

The study shows that the population of the wild Siberian tiger in China has shown a dynamic growth, and prompted the characteristics of the spatial distribution pattern of the Siberian tiger habitat.
The study evaluated the current landscape of the Siberian tiger habitat in China based on the home space area of ​​the wild Siberian tiger and prey biomass demand.
The protection potential of China, pointed out that "the next hot spot for tiger protection in the world will be in China
.
" The study identified 55 wild Siberian tigers (including 20 juveniles) through the image data recorded by automatic cameras, and the number of adult individuals increased from 7 in 2013 to 33 in 2018.

The study also found that there is a forest area of ​​47813 square kilometers with a stable distribution of Siberian tigers in China, of which the Laoyeling area is 18,029 square kilometers; the Zhangguangcailing area is 10941 square kilometers; the Wandashan area is 5580 square kilometers and the Xiaoxing'anling area is 13,263 square kilometers

Studies have shown that the ungulate prey in all landscape patches are mainly small roe deer, while the large ungulates that Siberian tigers prefer to prey, such as wild boar and red deer, are relatively lacking
.
The number of tiger populations supported by the current total biomass of prey in each habitat patch are 110 (Laoyeling), 56 (Zhangguangcailing), 14 (Wandashan) and 31 (Xiaoxinganling)

Therefore, in addition to the restoration of large-scale prey, the study also suggests that the protection of Siberian tigers in China should promote top-level national land and space utilization planning, effective man-made disturbance management, improved connectivity between landscape patches, and extensive international cooperation
