What is a microforest?
A microforest is a tiny forested area often within a city that grows into a dense, highly diverse ecosystem within just a few years thanks to the use of a specific planting method.The concept of a microforest comes from the Japanese botanist Akira Miyawaki. The aim is to achieve a large amount of biodiversity in a very small space to improve air quality, regulate the microclimate and create habitat for many small animals.
What advantages do microforests offer?
Microforests have numerous positive effects on their surroundings:
- They promote biodiversity: Microforests grow up to ten times faster than forests that are planted the traditional way and become a functioning ecosystem in just two years. This means they are an efficient reforesting method because in a relatively short amount of time they create habitats for plants and animals to promote the biodiversity of cities.
- They improve air quality: Microforests sequester carbon and filter out harmful substances and fine dust particles from the air. And they are natural air conditioners. Water evaporates from trees when it’s hot, which cools the air.
- They also minimize the risk of flooding: Through their dense vegetation and deep roots, microforests help soak up and store rainwater, which improves the soil structure and minimizes the risks of floods.
- They also improve the well-being of humans – green spaces have a positive effect on people’s emotional state. They reduce stress, improve a person’s mood and promote a general sense of well-being.
Project locations and implementation in Winterthur
AXA employees volunteer to plant the microforests together with Stadtgrün Winterthur. A total of two microforests are slated to be planted in Winterthur: One Am Brisiweg in the Veltheim neighborhood and one in Allmend Grüzefeld. Starting in March 2025, both of these areas will be open to the public.
