Miniature urban forests planted using a method invented by a
Japanese botanist in the 1970s are growing in popularity.
Dense copses bursting with biodiversity can thrive in areas
the size of a tennis court. Known as 'Miyawaki' forests, the trees grow more
quickly and absorb more CO2 than plantations grown for timber.
How much space do you think you need to grow a forest? Bigger
than a couple of tennis courts? Well, miniature forests are springing up on
patches of land in urban areas around the world, often planted by local
community groups using a method inspired by Japanese temples.
