Through numerous experiments, the Forest Restoration Research Unit at Chiang Mai University, Thailand, have found ways to optimise seedling vigour and health. As a result, they have developed an efficient way to restore tropical forest ecosystems, with advantages for biodiversity conservation, environmental protection and carbon storage.
Steve Elliott, the unit’s cofounder and research director, explains why forests do not restore themselves any more, and argues that reforestation must enter the drone age.
