Planting urban forests can boost biodiversity, help mitigate climate change, contribute to a cleaner air, and cool cities during heath waves. Above all, it looks like a lot of fun to plant and take care of these mini-forests with citizens or schools to green neighbourhoods. A good idea for BiodiverCities?
More on minitature urban forests here. A nice video by WEF is on their twitter page.
