Japanese technique of harvesting trees without cutting them

The Japanese use a forestry technique called daisugi to harvest wood from trees without cutting them down:

What it is
Daisugi is a Japanese technique that involves pruning the branches of a tree to create a platform for new shoots to grow from. The term translates to "platform cedar".

How it works
The technique involves cutting the trunk of a young tree to about 1 meter high. New shoots will grow from the stump, and the strongest shoots are left to grow. The remaining shoots are pruned back to about 50 centimeters. This process is repeated every 2–4 years to maintain the tree's straight grain.

Benefits
Daisugi is a sustainable method that allows loggers to harvest the upper portions of a tree while leaving the base and root structure intact. The wood produced is uniform, straight, and knot-free, making it ideal for construction.

Origin
Daisugi originated in Kyoto in the 14th or 15th century. It was developed to address a seedling shortage during a time of high demand for taruki, a type of lumber.

Uses
Today, daisugi is mostly used in gardens and bonsai, but it was originally developed as a forestry technique.
