Data for Mount Tai's ancient trees stored on digital ID cards

Nearly 20,000 ancient trees on the renowned Mount Tai in Shandong province now have "digital ID cards", the Mount Tai scenic area management committee said on Sunday.

The digital ID cards hold basic information on the trees collected by a new monitoring and management system.

Providing basic information about the trees, the system helps rangers examine growing environment and conditions, and monitor physiology, climate, diseases and pests.
