The other day, I participated in the "technical training to protect the forest road surface with little tricks" in the Kyoto-city forest in Keihoku, which was organized by the forest management group and Kyoto City.
In recent years, torrential rains have caused mountain slopes landslides all over Japan.
This time, before such a large-scale disaster occurs, we are trying to protect the mountain by using little tricks such as planting trees and using civil engineering techniques on the slightly collapsed slope to prevent disaster.
The lecturer was Mr. Takada, a forest advisor for Kyoto City, and civil engineering companies stuff and a local lumberjack.
・Little trick 1
Appropriate planting species
Each tree species have a suitable place, so we planted trees in suitable areas for each species.
Documents I got on the event.
It shows where to plant which species.
/Key points for planting trees
・Plant three trees in one place
This allows the tree to compete with other trees and grow faster than planting a single tree.
In addition, two out of three trees can die, so it's a risk hedge as well.
Planting three plants should be done with a good balance of lighting and other factors.
Plant two trees on the south side, plant one in between, etc.
・Observe the seedlings carefully before planting
In some cases, the stem of the seedling is bent, so it is easier for them to grow if they get planted in a similar environment in which they were originally grown.
Also, larger seedlings roots may be curled up in seedling pots, so you should untie them.
・Harden the soil
After planting, harden the soil well to prevent it from falling out. You can check by pulling them out if you can it's not hard enough.
・Protect the seedlings from funges
When planting, make sure that the bacteria in the soil don't get to the roots of the seedlings.
If the seedlings' roots are damaged, the seedlings will get sick.
・Protect trees from the deer
In areas where there are deer, the tree sprouts are eaten by the deer and die, so I put a net over them. When you put up the net, you should fix the net underneath so then deer cannot get in under the net.
・Trees like slopes
Garden trees, for example, are planted on a flat surface, but I've heard that trees basically grow stronger when planted on a slope. Because of drainage, and it's natural, etc.
Little trick 2
Use of expired fire hoses
Expired fire hoses are usually just disposed of, but they are still strong enough. It's a great way to reuse them.
Little trick 3
uses mesh and stakes to prevent further erosion where water flows on the slope.
little trick 4
Use eco planter.
It's made of woodchips that will get decomposed after a while. It looks nice as well.
The tree planting is very deep and interesting.
I hope that these little tricks will be used in the forests in your area to protect the mountains.
Satoyama Design(our company) and Perspective(company) and local forester are making "Forest of Crafts" project in Kyoto city forest.
(Perspective is co-chaired by Ms. Matsuyama, who teaches Japanese traditional crafts(Kogei) to people in Japan and abroad through educational programs, and Mr. Tsutsumi of Tsutsumi Asakichi Lacquer studio, who tries new ways to use lacquer while preserving tradition.)
Japanese traditional craftsmanship symbolizes the sustainable relationship between people and nature and between people and their lives. In order to reconnect these relationships, the Forest of Craft proposes a harmonious and sustainable society by creating a platform that connects people with nature and people with people through forest creation and making new items.
The first step in the forest is to plant lacquer trees and paulownia trees. (In Perspective, we held a workshop on making lacquered paulownia surfboards in Keihoku last year.)
In addition, we are preparing for workshops and other events so that many people can feel closer to the forest.
We are planning to hold workshops such as tree planting, charcoal making, wild grass enzyme juice making, woodfired bath, bushcraft, camping, off-grid related thing, eco-DIY, etc. on a regular basis after April, so we would like you to join us.

Sounds like fun, doesn't it?
The ladder will be a bridge between you and the forest. LOL.
We are looking for individuals who are interested in planting trees and companies who are willing to sponsor the project.
