“Camera trap footage taken between 2013 and 2018 identified 55 Amur tigers in four forested landscapes in northeastern China: Laoyeling, Zhang-Guangcailing, Wandashan, and the Lesser Khinghan Mountains. . . The reason for the tigers’ sudden appearance in northeast China is due, in a large part, to a Chinese national policy called the Natural Forest Protection Project (NFPP), Miquelle said. “By stopping [the] harvest[ing] of trees in many parts of China, they essentially made whole villages whose economy was based on timber harvest economic wastelands,” Miquelle said. “Many of these people have had to leave the region to find new work, thereby pulling more and more people out of the forests.” With the timber industry shutting down, the forests were able to recover, and that’s “a big reason why tigers are expanding.” "
