AI's Role in Saving the Endangered White-Headed Langur
In the depths of the limestone karst mountains of Guangxi, Southern China, technology is playing a crucial role in bringing a critically-endangered primate species back from the edge of extinction.
The white-headed langur, found exclusively in Chongzuo, is experiencing a population recovery driven by an intelligent monitoring platform that demonstrates how AI can solve complex conservation challenges.
Listed as Critically Endangered by the IUCN Red List of Threatened Species and the Red List of China's Vertebrates due to habitat fragmentation, the "stone mountain elf" is rarer than the giant panda, according to recent data, but is making a significant recovery in its fight for survival.
The turnaround is all thanks to collaborative efforts between the Guangxi Chongzuo White-headed Langur National Nature Reserve, local government, academia and the technology sector.
Bidding to overcome significant challenges presented by the area's rugged terrain, which hindered traditional patrol and monitoring methods, the nature reserve partnered with Huawei and the China-ASEAN Artificial Intelligence Application Cooperation Center to develop an intelligent monitoring platform powered by AI computing. Video-based animal monitoring devices were deployed along the cliffs, enabling the system to collect real-time data on the langurs' distribution, surroundings and patterns of activity.
AI-driven data analytics transform monitoring
The monitoring platform uses AI-driven automated labelling and data analytics to process information gathered by the devices.
This has enabled the development of a complete dashboard for visualised management, significantly enhancing the efficiency of data retrieval and analysis. To date, the system has recorded over 37,200 instances of langur activity, providing researchers with unprecedented insights into the species' behaviour and habitat use.
The AI system's ability to process complex geographical data and massive volumes of species data has proven particularly valuable in the challenging karst landscape. This terrain, characterised by steep limestone formations and fragmented habitats, would be extremely difficult to monitor using conventional methods alone.
While technology forms a critical component of the conservation effort, it operates within a comprehensive framework that includes legal protection and ecological restoration. The Chongzuo White-Headed Langur Habitat Protection Regulations – the first regulation of its kind in China – provides the legal foundation for protection efforts.
Under this framework, 77.6 hectares of habitat have been restored, two drinking water sources and 18 water drinking points for the langurs have been built, and two ecological corridors have been constructed. The combined approach appears to be working, with the white-headed langur population increasing to more than 1,400 across 130 groups.
"The growth of the white-headed langur population can be attributed to a combination of technology, legislation and ecological restoration efforts," says Nong Dengpan, Director of the Guangxi Chongzuo White-headed Langur National Nature Reserve Management Centre.
"Digital technology enables more precise observation of these limestone langurs and more informed management of their living environment. This integrated conservation model can serve as a reference for the protection and population recovery of other endangered primate species, such as the eastern black crested gibbon in Southeast Asia."
Technology supports broader conservation framework
As the langur is an umbrella species of the local karst ecosystem, the growth of its population could indicate broader improvements to the region's biodiversity.
Wild duck lettuce, a level-II protected species in China, was found in the reserve in 2024 for the first time, potentially signalling recovery in the fragile local ecosystem.
Tian Yongsheng, Deputy General Manager of Huawei Guangxi, adds: "Huawei is committed to conserving nature with technology. We work with global partners to support ecosystem conservation using digital technologies like 5G, cloud and AI.
"The success of the white-headed langur project demonstrates AI's immense value in processing complex geographical data and massive volumes of species data. We will continue using innovative technologies to protect biodiversity and enable the harmonious coexistence of humanity and nature."
By the end of last year, Huawei's digital inclusion projects for environmental protection had been implemented in 65 protected areas around the world.
Already, these projects are improving the efficiency of biodiversity conservation and the sustainable use and management of natural resources, demonstrating the scalability of AI-powered conservation solutions across diverse ecosystems and species.
