Cao Cao

Cao Cao, a female giant panda with the studbook number 342, was born on January 1, 1989, in the wild Minshan/Qionglai habitat regions of Sichuan, China. Her parents, Xing Xing and Mei Mei, were both wild-born giant pandas, and no further extended lineage details are documented in official studbook records for her wild-caught maternal and paternal lines. She was rescued and transferred to the China Conservation and Research Center for the Giant Panda on January 1, 1990, and has resided at the facility continuously in the decades since. As of 2024, she is one of the oldest recorded living giant pandas participating in formal captive breeding programs, a milestone that positions her as a high-priority subject for species-specific research.

Under the care of the China Conservation and Research Center, Cao Cao is part of the institution’s long-term captive breeding and endangered ursid research initiatives. Her daily health metrics, activity patterns, and dietary needs are closely tracked as a core component of the center’s longitudinal study of aged giant pandas, as wild-born individuals with multi-decade captive residence are extremely rare in the global panda conservation network. She has not been part of public display programs in recent years, as her care team prioritizes low-stress environments to support her advanced age and ongoing research contributions.

Cao Cao’s unique life history, spanning both wild early life and long-term captive residence, makes her an invaluable asset to global giant panda conservation efforts. Her extended lifespan provides rare empirical data on the physiological and behavioral adjustments giant pandas undergo when transitioning from wild to managed care, as well as baseline data on species longevity thresholds under human care. Her participation in gerontological research supports the development of improved care protocols for elderly giant pandas in both captive facilities and semi-wild release programs, directly contributing to evidence-based strategies for the long-term survival of the vulnerable species.
