A Pocket Forest is a densely-planted, multilayered, multi-species forest community small enough to fit in the space of a couple of parking spots.

Pocket Forests grow rapidly and reconnect fragmented habitats, accumulate carbon, reduce water runoff, create healthy soil, and foster biodiversity. They provide the foundation for an abundance of life. They are a fantastic tool for managing un- or under-used land spaces, turning them into low-maintenace, mini wildlife zones. 

This is such an amazingly simple idea!
