Bai Yun

Bai Yun (studbook number 371) is a female giant panda born on September 7, 1991, at the China Conservation and Research Center for the Giant Panda. Her birth was a notable early success for the center’s captive breeding program, and she is formally registered in global giant panda population databases maintained through international conservation collaboration. Her mother is Shi Shi, and her father is Pan Pan, the panda with studbook number 354; both parents were long-term residents of the China Conservation and Research Center for the Giant Panda and key contributors to the center’s early captive breeding efforts. Bai Yun’s lineage carries well-documented genetic heritage from wild giant panda founder populations, making her a genetically valuable individual for the managed global captive panda population.

Bai Yun currently resides at the China Conservation and Research Center for the Giant Panda in Sichuan, China, where she participates in the center’s official captive breeding and conservation research programs. These programs prioritize maintaining high levels of genetic diversity within the captive giant panda population, a core requirement for the long-term viability of the species and the success of potential future reintroduction efforts targeted at protected wild habitats in the Qinling and Minshan Mountains. As one of the longest-lived captive giant pandas on record, she has been the subject of long-term monitoring covering multiple facets of giant panda biology and care.

Over the course of her life, Bai Yun has produced multiple offspring that have been integrated into captive populations both in China and at international partner institutions, expanding the genetic diversity of the global captive giant panda pool significantly. The decades of data collected on her behavior, health trajectory, and aging process have provided researchers with critical baseline information to improve care protocols for captive pandas of all age groups. Her role as a prolific, genetically valuable contributor to captive breeding efforts is recognized as one of the many collective conservation achievements that supported the 2016 downlisting of giant pandas from Endangered to Vulnerable on the IUCN Red List of Threatened Species.
