Mini forest in Josephine Koch Park

Since the end of October 2023, a mini forest has been growing in Josephine Koch Park, modelled on a primeval forest as it would look without human activity. Normally, it would take around 200 years for such a forest to develop on its own. Using botanist Akira Miyawaki’s method, a similar result can be achieved in 20 years.
This method is based on the mechanisms and diversity of nature: 15 to 30 native tree and shrub species are planted in a single forest. These species work very well together and are perfectly adapted to the climatic conditions of the planting site.
This habitat becomes increasingly complex and, in balance with the current soil and climate conditions, forms a beautiful ecosystem that promotes increased biodiversity.

Urban and peri-urban areas

• Respect and/or improve the specific ecological characteristics of the area (e.g. the topography, the type of landscape, the local plant and animal life);
• Set up a biodiversity-friendly management system (e.g. rewilding, reduced mowing of parks, gardens, talus, ponds, no chemicals);
• As much naturalness as possible/as little alteration as possible of the initial landscape (landscape, quality of water, of soil, …);
• Incorporate the developments into the surrounding area and environment;
• Use native species/subspecies that are more resilient and resistant to climate change, if appropriate.

Maintenance was only carried out in the first two years after planting. During this time, the undergrowth was removed by hand so that the small trees and shrubs would not be overgrown by the faster-growing herbaceous undergrowth. After two years, the trees and shrubs are already so well developed that no further maintenance is required.
