From Earthwatch Europe and UKGBC:

Tiny Forest is an innovative tree planting initiative that establishes accessible, nature-rich green spaces in our towns and cities, where they are needed most by people and wildlife. The disproportionate power of a Tiny Forest is delivered through three positive impacts:

1. Physical: dense, fast-growing native woodlands, bringing a range of environmental benefits and consisting of around 600 trees planted in a tennis-court sized plot of 200m2, and using no chemicals.
2. Social: local communities, schools and businesses directly engaged in planting, maintaining and monitoring of the forests
3. Scientific: public and citizen science activities that support data collection on the environmental and social benefits of Tiny Forest, uploaded to Earthwatch’s open-access digital data platform.

Tiny Forest’s approach is about planting ‘the right trees in the right places’.
