Dr Susan Graham has helped build a drone system that can scan the land, identify ideal places to grow trees, and then fire germinated seeds into the soil.
Drones can plant in areas previously impossible to reach, like steep hills.


Key points:

• The drone system fires germinated seeds into soil
• Drones can plant in areas previously impossible to reach, like steep hills
• The technology could also help rehabilitate land once used by mines

 Not bad. Hope it works.
