| 英文摘要 | Père David's deer ( Elaphurus davidianus ) became extinct in the wild in China in the late 19th century ([ 1 ][1]), but after reintroduction three decades ago, the population has grown to more than 8000 individuals, with at least 2420 living in the wild in China ([ 2 ][2], [ 3 ][3]). This species reintroduction is considered one of the most successful stories in the world ([ 4 ][4]); it provides a watershed example of biodiversity conservation best practices for the upcoming UN Decade on Ecosystem Restoration. However, the species needs continued support to thrive.
Heavily endangered as a result of overhunting and habitat loss ([ 1 ][1]), the last of China's Père David's deer had been pillaged by Europeans and sent to zoos across Europe before the Qing Dynasty fell in 1912 ([ 1 ][1]). In 1985, nearly a century later, 38 deer were donated back to China for re-wilding ([ 5 ][5]). After the reintroduction of an additional 39 deer from zoos in England in 1986 ([ 6 ][6]), the population in Dafeng Milu National Nature Reserve grew to 5681 individuals ([ 2 ][2]). Père David's deer populations now cover all habitats in which they lived before the species' extinction in the wild.
The conservation of Père David's deer, however, faces ongoing challenges. The populations within China lack genetic diversity and are therefore susceptible to multiple risks, such as high miscarriage rates, reduced life span, and diseases ([ 4 ][4]). Wild populations are also limited by environmental constraints, keeping population numbers low and hindering stability. Moreover, there is no master plan for Père David's deer conservation at the national level and thus no coordinated monitoring platform or guidelines for overcoming inbreeding and environmental obstacles. Finally, there is a lack of international cooperation between researchers in China and abroad. National and international cooperation to strengthen monitoring of Père David's deer populations and to develop a shared database and germplasm databank between all countries with wild populations would be a major step forward for securing the long-term conservation of this species.
