Problem illustration

What if you could fit a whole forest in your backyard, or even in a tiny space the size of a few parking spots? Using the "Miyawaki method," people are planting "pocket forests" all over the world! Because the trees are planted so close together, they start a "magic race" to the sun, growing super fast to reach the light. Some have grown over 9 metres tall in just six years! These mini-forests act like giant sponges for water and provide a perfect home for birds and bugs right in the middle of busy cities. Learn more!

Wee Ones

If you plant a tiny tree seed in your pocket forest today, is it likely or unlikely that it will grow as tall as your house by tomorrow morning?

Little Kids

You are exploring a pocket forest with 15 tiny saplings. If you count 5 oak trees and the rest are maple trees, how many maple trees did you find?

Big Kids

In a dense pocket forest, scientists plant 3 trees in every square metre. If you have a small patch of land that is 9 square metres, how many trees can you plant in total?

The Sky's the Limit

A healthy pocket forest has a mix of different plants. If a forest has 40 tall trees and 10 short shrubs, what is the ratio of trees to shrubs?
