The Hainan Eld's deer, a rare and endangered species native to China's tropical island, Hainan, has become a symbol of ecological conservation. Once a species with only 26 individuals in the 1950s, the population has rebounded to over 1,000 today, thanks to local governments, organizations, experts and neighboring villagers.

The local authorities have implemented a comprehensive conservation strategy, including habitat restoration, dynamic monitoring, quantitative analysis and genetic diversity.
