Duan Lianru doesn't remember how many times she has met the "Miss Photogenic". The thee-year-old wild Siberian tiger seems to be a little heavier recently. Duan can always recognize (认 出) her easily. She has watched the tiger grow up--from when she was still a baby to the time she became old enough to leave her mother.
Duan works at a WildAid center. She has a very special job--making "ID cards" for Siberian tigers. With the help of 5, 000 cameras put in the wild, she watches hundreds of pictures on the computer every day. Then she records (录制) and compares them carefully. By doing so, she has collected a lot of information about the "King of the Forest". And the information is included (包含) in the "ID cards", including each tiger's patterns (花纹) , areas of activities, eating habits, and so on.
What Duan is doing is to protect (保护) Siberian tigers. The big cats mainly live in Russia's Far East and Northeast China. They're one of the world's most endangered (濒危) animals. Only about 500 Siberian tigers are living in the wild.
To save them, China set up the Northeast China Tiger National Park which has an area of over 14, 00 square kilometers and spans (横跨) Jilin and Heilongjiang province. Thanks to people like Duan, the number of wild Siberian tigers in the park is now more than 50. And they also live longer.
"What I am doing is meaningful. I hope that people and wild animals can live together peacefully and that nature will become more beautiful," Duan said.
