There is a traditional Japanese technique called "Daisugi" or "Yosegi" that has been practiced for centuries to produce wood without cutting down trees. Here's how it works:
1. Selective Logging: Instead of clear-cutting forests, which is detrimental to the ecosystem and disrupts natural growth patterns, the Japanese practice selective logging. They carefully choose specific trees to cut down while leaving others untouched.
2. Regeneration and Tending: After the selected trees are logged, the remaining stumps are left in the ground. This allows the trees to naturally regenerate and grow new shoots from the stumps.
3. Cuplike Branching: As the new shoots grow, they are carefully pruned and trained into a cuplike branching structure. The branches are bent horizontally and tied to external supports to create a vertically elongated tree shape.
4. Sustaining Multiple Growth Cycles: Once the shoot reaches a certain height, it can be cut off and utilized for woodworking purposes. However, instead of completely removing the tree, one or more new shoots are allowed to grow out from the top of the remaining stump. This process can be repeated over several growth cycles, often spanning several centuries.
5. Continuous Care and Maintenance: This unique method of tree training requires consistent care and maintenance. The branches need to be regularly pruned, tied, and shaped to maintain the desired cuplike form. Additionally, surrounding vegetation is carefully managed to ensure the trees receive adequate sunlight and nutrients.
By following the principles of Daisugi or Yosegi, the Japanese have been able to sustainably harvest wood without cutting down trees for centuries. This technique promotes forest regeneration, reduces the impact on the environment, and allows for a continuous supply of high-quality wood.
