Don’t plant trees to combat climate change plant mini-forests

Planting trees is one way of mitigating the impact of climate change, but planting mini-forests is a more effective alternative, says American nature and conservation writer Hannah Lewis.
Mini-forests are more likely to nurture ecosystems, rather than single trees planted here and there, and, as a result, live longer. And better still, mini-forests can be established anywhere, even in densely populated urban areas, where there’s even a few spare square metres of land available.
A mini-forest is a small ecologically robust forest that can be planted by communities in parks and cities, in schoolyards and churchyards, and beside busy roads. It’s flipped traditional landscaping on its head. You get more biodiversity and a different appearance. It’s a dense band of multi-layer trees as opposed to the elegant but less ecologically useful line of single species down the side of the street.
Lewis’ call is based on the work of late Japanese botanist Akira Miyawaki, who advocated the planting of small forests with native species, as a way of fostering the emergence of ecosystems.
