Miyawaki Method

Climate change and rapid urbanization are two main anthropogenic activities that causes destruction of plants and trees. In just few hours, the century old trees cut down for human development. The loss is irreversible. There is a strong need of conservation activities and plants restoration strategies for the preservation of the natural environment. The studies revealed that most of the forest recovery methods are time requiring and bring unfavorable results

The Miyawaki method is an effective method of afforestation. The Japanese botanist and plant ecologist known as Akira Miyawaki introduced this method. It is a random and dense plantation of native species. The purpose of the method is restoration of natural vegetation on degraded land. This method consists of plantation of various kinds of trees in a small pit. In this way, the plants grow in a closed environment enriches the green cover and grow together to become strong and healthy trees. The plants undergo co-existence and provide essential nutrients to one another. The study reveals that with the help of Miyawaki method the forests can grow up to 10 times faster, 30 times denser and 100 times more bio-diverse. The methodology is very effective as it helps 17 million trees to grow efficiently in 1700 different locations. The method involve:

  • Soil texture and biomass:

It is important to check the soil texture and biomass such as water holding capacity of the soil, nutrient retention, water infiltration, erodibility and root perforation capacity.

  • Selection of trees species:

This step of selection of species includes: database of all native species of the area, availability of native species saplings, and selection of five various forest species, 25-40% of supporting species and then minor species make up the rest.

  • Forest design:

In forest design the identification of the area is done. The project area comprised of 3 meters in width. The forest should be watered regularly for 2-3 years.

  • Preparation of area:

The area should be inspected properly. The process consists of removal of debris and weeds, installation of water facility, availability of fencing, physical demarcation, and mound identification (serial number in order for every 100 sp metres mounds)

  • Plant the Trees:

The forest is created on 100 square metre mound. There is first digging of earth to a depth of 1 metre on the 100 square metre land. Make the soil loose and shape the soil into a mound. In a Miyawaki method, all the saplings planted together. The plants placed to create a multi-layered natural forest. The formation of group of plants into different groups is essential such as shrub, sub tree, tree and canopy. These are planted in very square metre. There should be a difference of 60 cm between saplings, two trees of same kind should not place next to each other.

  • Monitoring of forest for three years:

There is a need for monitoring of forest for the duration of 8-12 months to check that if any changes require for improvement of results. The watering for forest is require once a day.
