Forty Ways to Know a Tree: Exploring Trees to Understand Nature

Discover the incredible life of trees through forty eye-opening short essays that explore trees as miraculous, living, breathing protectors of our Earth. Environmental activist and author Joan Maloof’s elegant writing turns science into storytelling. There are an estimated three trillion trees in the world, half as many as there once were. To honor and protect these vital organisms, a shift in perspective can help expand our understanding beyond simply appreciating trees' remarkable beauty to discovering the ways they are inextricably connected to our planet, our fellow species, and our spirits. Within these pages, biologist Joan Maloof offers forty distinct ways of encountering, exploring, and learning about a tree. Through engaging, impassioned essays, paired with beautiful watercolor illustrations, she invites us to get to know a tree: • By its leaves, whether it is needle-leaved or broad-leaved. Leaves can also be different on an individual tree; for example, those on the lower part, called shade leaves, tend to be larger to catch what sunlight they can. • Through its rings, the only sure way of telling its age. The oldest documented tree ever counted was a bristlecone with 4,500 rings. • From its birds. For example, avian migration is driven by how weather affects trees, like the honey mesquite trees’ yellow blooms that cue migratory birds to stop and feed on the spiders found in their blossoms. • By its song, either through the many organisms living there or the wind moving through its branches and leaves. Trees sound different in winter and summer, and healthy trees sound different than sick ones. • And so much more. Each profile is illustrated with a particular species, representing dozens from all around the world, which combine to create a broader canvas of tree knowledge. This book celebrates the tree itself, with its many roles and parts, as well as its invaluable services to humans and wildlife—providing food, shelter, clean air, water, and, to many, simple joy. - Joan Maloof & Sara Nunan - 192 pages - 6.1 inches W x 8.8 inches L - Hardcover - Princeton Architectural Press - 2026 - Nature - Item #: 9781797238036
