Planting trees in Tiny Forests

Tiny Forests

Since 2020, Earthwatch has worked with partners and different communities across the UK to plant over 250 Tiny Forests – bringing the benefits of a forest right into the heart of our cities and urban spaces. Creating these dense, thriving forests uses the Miyawaki method of planting based on ‘potential natural vegetation’ (PNV), forest structure and an understanding of how things could grow naturally if humans didn’t interfere. A huge diversity of native species and different plant structures are planted very closely together, mimicking what would happen in nature if a forest was regenerating.

A solution for urban tree planting

A Tiny Forest typically consists of 600 trees planted densely in a tennis-court size plot. Because they are so small, they are often planted in urban locations where space is tight and nature is most needed. Research studies indicate that it can be cheaper to grow a Tiny Forest than more conventional spread-out urban tree planting; more collective effort is needed upfront in planting the forest but tree survival rates are also higher and the self-sustaining forest requires very little maintenance. Tiny Forests become less tiny as more communities are replicating them across Britain and Earthwatch’s goal is to have 500 forests planted before 2030.

A tiny forest with big biodiversity

Tiny Forests grow up to 10 times faster, are 30 times denser and support up to 100 times more biodiversity than conventional ways of planting trees. Involving the local community is integral to this different approach – not because more help is needed at the start to prepare the soil and plant so many trees, but because more people can have an experience and powerful connection with nature; and that link is a key measure of its success. Links with Tiny Forests can work in other powerful ways too: the Tiny Forest in the town of Barry has become part of the Welsh national forest and an ambitious scheme to create a network of woodland that runs the entire length and breadth of the Wales.
