The main topic is that they tried to plant a forest in the backyard of people’s house. 

He is an industrial engineer who worked at Toyota previous. He learned how to convert natural resources into products. But most of the products can never become a natural resource again. They separate the elements from nature and convert them into an irreversible state.  

The natural system produces by bringing elements together, atom by atom. All the natural products become a natural resource again. They made 75 forests in 25 cities across the world. They tried to bring every single elements together to make a forest and then let nature take over. 

   They touch, feel and even taste it to identify what properties it lacks. It has to make sure that water can seep in. By mixing some local biomass available around, it can help soil become more porous in order to seeping in waters to stay moist. 

Plant need water, sunlight and nutrition. They don’t just add nutrition directly to the soil, because it will against nature. They add microorganisms to the soil. They produce the nutrients in the soil naturally. They feed on the biomass they have mixed in the soil which will eat and multiply. 

They survey the native tree species of the place. The rule is that whatever existed before human intervention is native. They survey a national park to find the last remains of a natural forest. They survey the sacred groves, or sacred forests around old temples. If they don’t find anything, they will go to museums to see the seeds or wood of trees existing there a long time ago. Moreover, they research old paintings, poems and literature from the place, to identify the tree species belonging there. 

Next Steps:

canopy layer

They collect the seeds and germinate saplings to make sure that trees belonging to the same layer are not planted next to each other. They plant the saplings close to each other. On the surface, they spread a thick layer of mulch to keep the soil stay moist. 

In the first 3 months, roots reach a depth of one meter, tightly holding the soil. Microbes and fungi live throughout this network of roots. Those microbes are going to get the nutrition to the tree. 

Once the roots are established, forest starts growing on the surface. As the forest grows they keep watering it - for the next 2 or 3 years. During those beginning years, people remove the weeds growing on the ground to stop blocking the sunlight. Until the stage, every single drop of water that falls into the forest doesn’t evaporate back into the atmosphere. They gradually reduce and eventually stop watering the forest. The forest floor still can stays moist. Now, the forest probably grow forever.
