The Siberian tigers have expanded its range from the China-Russia border area to deeper into the northeast China, according to research on footprints and monitoring video jointly conducted by the World Wildlife Fund and Beijing Normal University. Long-term monitoring has shown Siberian tigers moving from Hunchun Nature Reserve on the Russian border to Wangqing and Huangnihe nature reserves in Jilin Province, some distance from the frontier. Six have been spotted in Huangnihe in recent years and three are known to be resident there, according to the reserve. Researchers of Huangnihe nature reserves found some paw prints on trees in Malugou forest zone when they were patrolling along the mountains in March, which were confirmed left by the Siberian tigers. Not far from the trees, the researchers also found the remains of a wild boar who had been eaten by a Siberian tiger. “This is the remains of the wild boar left by the Siberian tiger. Only the head and four hooves of the boar were left. The boar was not big, about 160 or 170 jin (80 to 85 kilograms). So thick a bone has been crunched. You see the biting mark of the tiger,“ said Zhang Xiaodong, researcher of the Management Bureau of Huangnihe National Nature Reserve. The researchers have found hairs, footprints, feces of the Siberian tigers in areas of 19 square meters in the Huangnihe Nature Reserve. Meanwhile, they have recorded video of Siberian tigers having food and doing other activities with infrared cameras. On April 27, 2015, an adult male Siberian tiger was recorded walking within the range of an infrared camera and disappearing in the darkness. Video of the Siberian tigers eating other animals were also recorded many times from Sept. 29, 2014 to Nov. 18, 2014. At least two male Siberian tigers have appeared in the inland area of the Huangnihe region between 2014 to 2016, according to the monitoring data.
