Miyawaki forests are denser and more biodiverse than other kinds of woods and can be easily planted in all sorts of places, from residential neighbourhoods, to wastelands, or even school yards.

Fast-growing Miyawaki tiny-forests spring up across Europe to aid climate

Tiny, dense forests are appearing around Europe as part of a movement aimed at restoring biodiversity and fighting the climate situation. Often located in schoolyards or alongside roads, the forests can be as small as a tennis court. They are based on the work of Japanese botanist Akira Miyawaki, who has planted more than 1,000 of these mini-forests in Japan, Malaysia and elsewhere.

Usually, a planted forest takes about 100 years to develop into a “real” forest. A new forestation technique could kick start this process.

Natural forests can store 40x more carbon than single-species plantations

Advocates for the Miyawaki method say the miniature forests grow 10x faster and become 30x denser and 100x more biodiverse than those planted by conventional methods. This result is achieved by planting saplings close together, three per square metre, using native varieties adapted to local conditions. A wide variety of species – ideally 30 or more – are planted to recreate the layers of a natural forest.

Scientists say such ecosystems are key to meeting climate goals, estimating that natural forests can store 40x more carbon than single-species plantations. The Miyawaki forests are designed to regenerate land in far less time than the 70-plus years it takes a forest to recover on its own.

This technique works worldwide irrespective of soil and climatic conditions. Over 2000 forests were successfully created using this method. Doctor Akira Miyawaki, botanist and professor, is the inventor of the technique in 1980. He is a recipient of the 2006 Blue Planet Prize, which is the equivalent of a Nobel Prize in ecology.

Mini forests help with urban biodiversity

In 2017, researchers at Wageningen University in the Netherlands monitored newly planted mini-forests and concluded that they “increase the biodiversity compared to the nearby forest. Both the number of species groups and the number of individuals is generally higher than in the reference forests.”

The higher biodiversity is due partly to the forests’ young age and openness, explained Fabrice Ottburg, an animal ecologist who led the Wageningen study. This allows more sunlight to reach flowering plants that attract pollinators. Diversity is also boosted by planting multiple species, which “provide more variety in food and shelter for a higher diversity of animals like insects, snails, butterflies, amphibians, bugs, grasshoppers”, Ottburg said.

Due to the special Tiny Forest-technique, the forests grow up to ten times faster than normal, are thirty times more dense than other forests and they contain a biodiversity that is a hundred times more diverse. Due to its limited need for space and flexible usage, Tiny Forests can be easily planted in all sorts of places and surroundings, whether it is near residential neighbourhoods, on wastelands, or at school yards.

Groups in The Netherlands, France and Belgium have been creating new mini forests

In the Netherlands, the conservation group IVN Nature Education has helped cities and households to plant 100 Miyawaki-style forests since 2015. It is on track to more than double that number by 2022 and is working on similar efforts in a dozen other countries. Assorted groups in Belgium and France have recently created at least 40 mini-forests.

The first in France was planted in March 2018 beside a busy four-lane road on the edge of Paris. The dense thicket was intended to reduce noise and filter air for the adjacent neighbourhood. On the day of planting, 40 people gathered with 31 species of saplings to bring new life to ground that had been prepared with compost from local horse stables.

Two years earlier, Enrico Fusto and Damien Saraceni had applied for funding from Paris’s participatory budget, a scheme that asks residents for ideas about how to spend 5% of the city’s funds. The pair proposed mini-forests, saying they could help increase the level of tree cover in the city, which is currently less than 10%, much lower than many other major cities. “Each community can be the protagonist of its own restoration story,” Fusto told the Guardian.

In Toulouse, a mini-forest group planted 1,200 saplings on a 400 sq metre patch in March.

Nicolas de Brabandère, a Belgian naturalist and founder of Urban Forests, began planting Miyawaki-style forests in 2016, organising volunteers and local authorities to plant 300 saplings on a grassy strip of land near a road. Now his first forest is 3 metres tall, its floor a thick layer of humus.

De Brabandère believes the participatory nature and speed of a mini-forest is what appeals to people, and he predicts a bright future for the movement. “Every time I tell the story, everybody likes it,” he told The Guardian. “So I have a good feeling the trend will continue.”

Vegetation becomes much denser than conventional plantations, and it has the structure of a mature natural forest.

It is a multi-storey structure, where different levels of vegetation appear. The forest thus structured delivers many benefits in the form of ecosystem services.

A forest planted by humans, then left to nature’s own devices, typically takes at least 100 years to mature. But what if we could make the process happen ten times faster? In this short talk, eco-entrepreneur (and TED Fellow) Shubhendu Sharma explains how to create a mini-forest ecosystem anywhere.

How to Grow a Forest Using The Miyawaki Method In Minimal Space

Invented by and named after Japanese botanist Akira Miyawaki, the ‘Miyawaki Method’ is a unique technique to grow forests. Under the approach, dozens of native species are planted in the same area, close to each other, which ensures that the plants receive sunlight only from the top, and grow upwards than sideways. It requires very little space (a minimum of 20 square feet), plants grow ten times faster, and the forest becomes maintenance-free in three years! Check out here how to grow your forest.
