Lhalu Wetland, known as the "lungs of Lhasa" and the largest urban natural wetland on the Qinghai-Tibet Plateau, has achieved significant ecological recovery over the past 20 years, according to the latest monitoring data.

Since 2005, the wetland's water coverage has increased by 232 percent, while sandy and bare land areas have shrunk by 70 percent. Vegetation coverage rose by 44 percent. The number of nationally protected wild species recorded in the wetland has grown from nine to 25, with sightings of rare species such as black-necked cranes, white-lipped deer, and otters becoming more frequent, according to a report released by the Lhalu Wetland National Nature Reserve.

At the end of 2025, the wetland was recognized by the World Record Certification Agency as the world's highest urban natural wetland.

A key ecological barrier for water conservation and climate regulation in Lhasa, Lhalu Wetland has undergone systematic protection and restoration since becoming a national nature reserve. Local authorities have prioritized conservation, scientific management, and ecological rehabilitation to strengthen the wetland's ecosystem.

The reserve now hosts 438 species of vascular plants and 174 bird species, including 28 under national protection. The number of breeding waterbird species has increased from one to 12. Researchers have also identified three second-class nationally protected fish species through environmental DNA monitoring.

Technology has played an increasing role in conservation efforts. Lhasa has established an ecological monitoring platform featuring AI-powered bird identification and underwater fish monitoring systems, enabling more precise management. The wetland also serves as a center for ecological education and public outreach.

Lhamo Tsering, director of the reserve administration bureau, said the latest monitoring report will support future conservation, scientific research, and environmental education efforts on the Qinghai-Tibet Plateau.
