Abstract: The Chinese pangolin (Manis pentadactyla), a Class I protected species in China, faces critical endangerment due to anthropogenic pressures, habitat degradation, and climate change. Except for Taiwan, the distribution range of Chinese pangolins in China has significantly decreased. The Chinese pangolin’s suitable habitats are shaped by an intricate interplay of factors including vegetation, human activity, climate, and topography. Chinese pangolins are an enigmatic, nocturnal species and possess modest home ranges and subsist primarily on a diet of termites and ants. Their burrowing behavior alters soil structure, enhances forest habitat heterogeneity, and provides additional resources for sympatric species, making them important ecosystem engineers in forest ecosystems. While ex-situ conservation through artificial breeding serves as a crucial complement to in-situ efforts, it presents critical challenges, including low survival rates of rescued individuals, enhanced disease susceptibility, difficulties in formulating appropriate artificial diets, poor sperm quality, and low offspring viability. The primary threats to Chinese pangolins encompass poaching, habitat fragmentation and loss, limited genetic dispersal, and the risk of extinction due to critically small populations. To address these multifaceted challenges, comprehensive conservation strategies need to be developed meticulously, such as bolstering law enforcement, advancing scientific research, safeguarding habitats, refining artificial breeding techniques, enhancing public awareness and education, and fostering international collaboration. Through the concerted implementation of these conservation measures, it is anticipated that the conservation scenario for Chinese pangolins will improve significantly, potentially leading to a gradual recovery of its population size.
