Tree Day

An hourly guide that spotlights twenty-four trees as they flower, root, and host diverse forest life.

In this short book, tree-top explorer Meg Lowman guides us through a global forest. Each chapter of Tree Day introduces a single tree during a single hour, highlighting twenty-four sylvian species from around the world.

In the dark of Yemen's night, it is too early to see the red sap from which the dragon's blood tree gets its name. But if we watch closely, we will see nocturnal geckos carry the trees' pollen in their snouts.

Later, in the Pacific Northwest, we climb the world's tallest species, the coastal redwood. The morning fog is a reminder that redwoods absorb water through their roots and canopies, helping them survive such heights.

The sun is already low in the sky on an autumn afternoon. Given the darkness of this New England forest, the sugar maple's leaves have stopped producing chlorophyll that converts light into energy—and green gives way to vivid crimson foliage. After many hours of boiling, the maple sap makes delicious maple syrup.

As the sun sets in Mexico, we observe the origin of another treat, chocolate. The cocoa tree's flowers sprout along its trunk and branches, allowing easy access for tiny insects like midges that pollinate the tree and make a start to delicious food for humans, monkeys, bats, and squirrels.

By the end of our tree day, we will understand that trees are the silent caretakers of our planet, providing us with medicines, foods, machinery for making fresh water and oxygen, and more.

For each hour, celebrated artist Thibaud Hérem has depicted these trees with gorgeous pen and ink illustrations. Working together to narrate and illustrate these unique moments in time, Lowman and Hérem have created an engaging read that is a perfect way to spend an hour or two—and a true gift for anyone who has ever looked up at a tree in wonder.
