Welcome to the world of Leaflings, the secret guardians of the trees.

Among the branches and roots of some of our planet's most important inhabitants live the leaflings. These tiny creatures protect trees and help manage their interactions, their cycles and tell their stories. In A Field Guide to Leaflings, meet leaflings from all over the world and the trees they live with.

Travel from an ancient holly tree in Ireland, to a cherry blossom in Japan, and climb to the highest branches of a giant redwood in California. The leaflings will show you how trees breathe, make food, support many forms of life and what they mean to people all around the world.
