In the Siberian Tiger and Leopard National Park, there is a special profession - the "household registration officer" of Siberian tigers. The Siberian tiger's pattern is as unique as a human's fingerprint. The "household registration officer" needs to distinguish different individuals based on the position, length, width, color and shape of the Siberian tiger's body pattern, and provide an "ID card" for the Siberian tiger and an "ID card" for the Siberian tiger family. Drawing a family tree.” Duan Lianru, who works at the Scientific Research and Monitoring Center of the Hunchun Branch of the Northeast Tiger and Leopard National Park Administration, is responsible for this work.
The Siberian tiger is one of the flagship species for global biodiversity conservation. To protect the Siberian tiger and its habitat, China has established the Siberian Tiger and Leopard National Park, which covers an area of more than 14,000 square kilometers and spans Jilin and Heilongjiang provinces. There are more than 5,000 infrared cameras distributed in the jurisdiction where Duan Lianru works. Every day, she compares hundreds of Siberian tiger monitoring images.
"ID cards" and "genealogy" can provide a large amount of basic data for the scientific research and protection of Siberian tigers. "Registration officers" not only enjoy the fun of "raising tigers in the cloud", but also devote themselves to the protection of tigers and leopards in obscurity. In recent years, with the improvement of the ecological environment, more and more tigers and leopards have returned. Relevant data shows that before the establishment of the Siberian Tiger and Leopard National Park, 33% of Siberian tiger cubs survived to adulthood. Now more than 50% of Siberian tiger cubs survive to adulthood.
The Siberian tigers didn't know that there was a "household registration official" who cared about them on the other side of the infrared camera, but Duan Lianru still worked hard. "I hope that people and wild animals can live in harmony, and that nature will become more and more beautiful," Duan Lianru said.
