Tech-Driven Restoration: Saving the World’s Critically Endangered White-headed Langur

CHONGZUO, CHINA – 27 March 2026 – In the rugged karst mountains of Guangxi in Southern China, a primate species once on the brink of extinction – the white-headed langur – is steadily recovering in population thanks to a range of measures that bring together technology, law enforcement, and ecological restoration.

Found exclusively in Chongzuo, Guangxi, the white-headed langur is listed as Critically Endangered by the IUCN Red List of Threatened Species and the Red List of China’s Vertebrates. New monitoring data reveals that the “stone mountain elf”, which is even rarer than the giant panda, is no longer on the brink of extinction. Through the combined efforts of the local government, the nature reserve, academia, and the tech sector, the survival crisis triggered by habitat fragmentation has been significantly reversed for this species.
