China's tree-planting drive is entering a new phase. As the country marked its 48th National Tree Planting Day on March 12, the focus has been shifting from planting more trees to building healthier, higher-quality forests, with digital technology and artificial intelligence playing a growing role.

Using satellite monitoring, drones and digital twin systems, researchers can now track forests with far greater accuracy. These tools help scientists assess forest quality, guide planting in real time and ensure each new forest brings stronger ecological benefits.
