Tiny urban forests are having a hugely positive impact

With one in three people in England lacking access to nature-rich spaces, this micro-foresting method is being deployed to change that.  

Have you heard of the Miyawaki foresting method?

It’s a Japanese-style tree-planting technique that involves placing a strategically diverse group of native woodland trees within a small area of land. The goal is to choose species that will work together in harmony, growing over time into a bustling micro-forest.

Growing at faster rates than conventionally planted trees and covering the surface area of a tennis court, these types of tiny forests are perfect for bringing nature back to heavily urbanised areas.

The method was first invented by Japanese ecologist Akira Miyawaki in the 1970s, but is now being deployed all over the world.

In most cases, these microforests can be found planted within housing estates, on school properties, and along the edges of urban areas.

Miyawaki forests have been successful in creating a new habitat and safe haven for wildlife, all while potentially improving carbon storage capabilities of surrounding lands.

These plots also boast higher survival rates when compared to those that use conventional tree planting methods because each species has been chosen to support the one beside it, without competing for resources or hogging essential space.

When planted strategically, these forests generate a complete plant community, with distinct layers from the ground all the way up to tree canopies. The best part? They are totally self-sustaining within 2-4 years of growth.

Earthwatch is an environmental charity deploying the Miyawaki method in urban areas across the European continent.

So far, it has planted more than 280 forests across the UK alone.

Of course, no nature restoration project is completely fool-proof.

While some areas in England are showing immense success – two tiny forests near Oxford have been flourishing for the last couple of years – there are obstacles to creating Miyawaki plots.

Requiring a diverse range of sapling species, these plots can be expensive to launch. Additional costs also rack up with the need to prepare the soil and maintain the trees’ health in their initial years.

The UK’s unique climate also makes tree mortality a common concern. Still, many would argue that the short-term cost of creating tiny forests outweighs the long term gains reaped from them.

By improving accessibility to green areas, councils can reduce loneliness in their community and help connect individuals through nature – all while improving local air quality, cooling surrounding air, and bolstering biodiversity.

Seems like a no-brainer, right?
