What scientific information people increase the tree supply during the tokugawa shogunate?

During this period, about 300 years ago, Japan was facing ecological disaster because of deforestation due to unsustainable forest harvesting practices. It is not entirely clear how it was achieved, but people in Japan, through co-operation, started practicing sustainable forest management. They also started tree plantations to re-forest deforested areas. The tree plantations led to advances in silvicultural technology, including seed production, tree cuttings, pruning and thinning. Therefore, developed scientific information in silviculture and forest management allowed Japan to increase the number of trees during this period.
