Journalist Marguerite Holloway arrives at the Women's Tree Climbing Workshop as a climbing novice, but with a passion for trees and a deep concern about their future. Run by twin sister tree doctors Bear LeVangie and Melissa LeVangie Ingersoll, the workshop helps people develop impressive technical skills and ascend into the canopy. As Holloway tackles unfamiliar equipment and dizzying heights, she learns about the science of trees and tells the stories of charismatic species, including hemlock, aspen, Atlantic white cedar, oak, and beech. She spotlights experts who are chronicling the great dying that is underway in forests around the world as trees face simultaneous and accelerating threats from drought, heat, floods, disease, and other disruptions.

As she climbs, Holloway also comes to understand the profound significance of trees in her relationship with her late mother and brother. The book's rousing final chapter offers something new: a grander environmental and arboreal optimism, in which the story of trees and their resilience meshes with that of people working to steward the forests of the future, and of community found among fellow tree climbers. A lyrical work of memoir and reportage, Take to the Trees sounds the alarm about rapid arboreal decline while also offering hope about how we might care for our forests and ourselves.
