Giant panda Xian Xian has food at the second-phase giant panda wild training fields of Tiantai Mountain in Wolong National Nature Reserve in southwest China's Sichuan Province, June 24, 2024. In recent years, China has made significant progress in panda conservation through a series of measures, including forest and wildlife protection as well as the construction of giant panda national parks. The wild giant panda population in China has grown from about 1,100 in the 1980s to nearly 1,900.

Giant panda reintroduction refers to releasing captive-bred giant pandas to their historical distribution areas to live and reproduce after acclimatization training so as to rebuild the wild population of the species.

China Conservation and Research Center for the Giant Panda (CCRCGP) started a reintroduction program in 2003. It has reintroduced eleven pandas into the wild, nine of which survived.

In the future, the center will continue to train more individual panda cubs using the mother-cub process before releasing them into the wild, while establishing small wild populations at the same time. (Xinhua/Shen Bohan)
