Fast-growing mini-forests spring up in Europe to aid climate

Miyawaki forests are denser and said to be more biodiverse than other kinds of woods

Tiny, dense forests are springing up around Europe as part of a movement aimed at restoring biodiversity and fighting the climate crisis.

Often sited in schoolyards or alongside roads, the forests can be as small as a tennis court. They are based on the work of the Japanese botanist Akira Miyawaki, who has planted more than 1,000 such forests in Japan, Malaysia and elsewhere.
