Sacred trees are a cornerstone of our national identity. They transcend simple economics and sit at the centre of the sacred — sentinels in ceremony, birthing and burials.
Despite their good intentions, cities rarely have the full set of skills and capabilities to turn their plans into a reality. Our research looks at what needs to change.

Advanced techniques allowed our research team to build an open database of billions of individual trees and challenge some common perceptions about vegetation in arid and semi-arid zones.
