The Sichuan Province recently launched its third census of ancient and famous trees, with the Implementation Plan jointly issued by the Sichuan Province Greenery Committee Office, Sichuan Province Forestry and Grassland Bureau, and Sichuan Province Housing and Urban Construction Bureau. The census aims to fully grasp the resources of ancient and famous trees, providing data support for their scientific protection and management.

Building on the scope of the second census, the new survey expands to national parks, nature reserves, and state-owned forest areas to achieve full coverage. The core tasks of the census include: re-evaluating registered ancient and famous trees, investigating new resources, and conducting special surveys of ancient tree clusters.

According to the plan, the census will follow relevant technical specifications, adopting differentiated methods based on the distribution characteristics of ancient trees and factors such as topography. The focus will be on updating information such as tree height, breast diameter, and growth momentum, and noting the causes of death and disposal measures for deceased ancient trees.

As a major province rich in forest resources, Sichuan possesses a large number of ancient and famous trees. By the end of 2024, the province had a total of 78,151 ancient and famous trees, including 97 famous trees, 11,356 first-class ancient trees, 7,212 second-class, and 59,497 third-class ancient trees.
