China’s remarkable efforts to revive the milu deer population have been celebrated at the 2025 International Symposium on Milu and Ecological Conservation in Beijing. The event, held from October 24 to 25 as part of the Zhongguancun Forum series, brought together over 100 experts from nine countries, including zoologists, ecologists, and conservationists. Since the reintroduction program began in 1985 in collaboration with the United Kingdom, the milu deer population has surged from a mere 77 to approximately 15,000—a staggering 200-fold increase. Initially confined to two reserves in Beijing and Jiangsu province, the deer now inhabit over 100 breeding populations across 27 provinces. Moreover, wild populations have flourished, with six groups totaling more than 6,000 animals thriving in various regions. This extensive network is hailed as the world’s largest and most comprehensive system for milu conservation, setting a global benchmark for wildlife reintroduction efforts.
