Guiyang City and Gui'an New Area in Southwest China's Guizhou province have made significant strides in protecting ancient and notable trees, reinforcing efforts to preserve biodiversity and enhance ecological development. To date, 4,032 such trees have been registered across the region.

Through surveys and verification, a comprehensive spatial database has been established, enabling digital management of each tree with a unique ID and QR code – a "one tree, one file, one code" system. Of the 4,032 trees on record (including two notable trees), 322 are classified as first-class, 765 as second-class, and 2,944 as third-class. Common species include Chinese cypress, Chinese hackberry, ginkgo, and Chinese honey locust.

To restore aging trees, Guiyang and Gui'an follow industry standards and consult experts for on-site assessments. Restoration efforts include pruning, cleaning decayed wood, filling cavities, pest control, and underground work such as digging revitalization trenches, installing ventilation pipes, and applying root fertilizers.

Through events and field research, Guiyang and Gui'an are uncovering the stories behind these living relics, blending conservation with heritage to promote awareness and appreciation.
