The rare jungle plants that ‘bleed’ nickel

Rare and valuable plants that naturally “mine” large quantities of nickel are deemed  to be hiding in Indonesia’s forests – but it is a struggle to discover them before they are removed from our planet

Some Sixteen years ago, Aiyen Tjoa was in the process of exploring a small mining town of Sorowako , which is in the heart of the Indonesian island of Sulawesi. Sorowako once had been a home to immense diversity of many plants, and most of them were found nowhere else on this planet But then the small town became the hub of one of the largest nickel mining areas in the world, with one actual company alone extracting 5% of the global nickel supply.

When Tjoa, a soil biologist and lecturer in Tadulako University in Central Sulawesi, arrived in Sorowako in 2004, most of the lush vegetation had already been wiped out because of mining, leaving barren soil and dusty roads behind it

But some bushes and young trees somehow survived. Back then, Tjoa was eager to find those rare plants that were adapting well to their new, nickel-rich surroundings. These, she reasoned, could be “super plants” capable of taking up high levels of nickel from the soil and storing it in surprisingly high quantities. As well as cleaning the soil, these nickel-rich plants could be “mined” to provide an alternative source of the metal, allowing nickel to be harvested without destroying the ecosystem.
