Discusses various parts of trees and their functions, including the bark, sapwood tubes, roots, and leaves.

Why should you be a friend to trees? Trees are a valuable natural resource. People depend on trees for food, and animals depend on trees for food and shelter. But most important, we depend on trees because they add oxygen, a gas we all need, to the air. While trees give us many wonderful products, we must also protect them because we can't live without them.

Robert Penn cut down an ash tree to see how many things could be made from it. After all, ash is the tree we have made the greatest and most varied use of over the course of human history. Journeying from Wales across Europe and Ireland to the USA, Robert finds that the ancient skills and knowledge of the properties of ash, developed over millennia making wheels and arrows, furniture and baseball bats, are far from dead. The book chronicles how the urge to understand and appreciate trees still runs through us all like grain through wood.

One hundred stunning black-and-white photographs capture the simple pleasures of walking in the woods, the restorative rhythms of nature, the spiritual qualities of deep forests, and our own connection with the natural world as they reveal the beauty of a variety of trees in different regions of the world.

WINNER OF THE 2018 JOHN BURROUGHS MEDAL FOR OUTSTANDING NATURAL HISTORY WRITING “Both a love song to trees, an exploration of their biology, and a wonderfully philosophical analysis of their role they play in human history and in modern culture.” —Science Friday The author of Sounds Wild and Broken and the Pulitzer Prize finalist The Forest Unseen visits with nature’s most magnificent networkers — trees David Haskell has won acclaim for eloquent writing and deep engagement with the natural world. Now, he brings his powers of observation to the biological networks that surround all species, including humans. Haskell repeatedly visits a dozen trees, exploring connections with people, microbes, fungi, and other plants and animals. He takes us to trees in cities (from Manhattan to Jerusalem), forests (Amazonian, North American, and boreal) and areas on the front lines of environmental change (eroding coastlines, burned mountainsides, and war zones.) In each place he shows how human history, ecology, and well-being are intimately intertwined with the lives of trees. Scientific, lyrical, and contemplative, Haskell reveals the biological connections that underpin all life. In a world beset by barriers, he reminds us that life’s substance and beauty emerge from relationship and interdependence.

Winner of the Pulitzer Prize in Fiction Winner of the William Dean Howells Medal Shortlisted for the Man Booker Prize Over One Year on the New York Times Bestseller List A New York Times Notable Book and a Washington Post, Time, Oprah Magazine, Newsweek, Chicago Tribune, and Kirkus Reviews Best Book of the Year "The best novel ever written about trees, and really just one of the best novels, period." —Ann Patchett The Overstory, winner of the 2019 Pulitzer Prize in Fiction, is a sweeping, impassioned work of activism and resistance that is also a stunning evocation of—and paean to—the natural world. From the roots to the crown and back to the seeds, Richard Powers’s twelfth novel unfolds in concentric rings of interlocking fables that range from antebellum New York to the late twentieth-century Timber Wars of the Pacific Northwest and beyond. There is a world alongside ours—vast, slow, interconnected, resourceful, magnificently inventive, and almost invisible to us. This is the story of a handful of people who learn how to see that world and who are drawn up into its unfolding catastrophe.
