Two gibbon species declared extinct in the wild in China

An assessment report on the endangered status of primates in China was released on Tuesday, indicating that the white-handed gibbon and northern white-cheeked gibbon have not been seen in the wild in the past few decades, meeting the criteria for being declared extinct in the wild, according to ScienceNet.cn. In the past 45 years, the population of the white-handed gibbon has declined steadily due to habitat loss, hunting, and pet trading, according to the report.
