About the Book

Emmy‑nominated filmmaker and University of Cambridge Environmental Psychologist Lindsay Branham invites readers into an embodied, reciprocal relationship with trees to heal our severed connections to ourselves and the earth, returning home to the living world.

Heartwood: The Wisdom and Healing Kinship of Trees

In the midst of the California wildfire season, Lindsay Branham was besieged by unexplainable health symptoms. Her descent into chronic illness challenged her notion of Western frameworks of “healing,” compounded alongside rapid ecological loss. Through a catalytic love affair with a family of trees in the Roaring Fork Valley of Colorado, an odyssey of healing unfolds—a poetic evocation to love the Earth, and to be loved back.

What if human and planetary health is connected? What if healing is an embodied ecological process, not an outcome? What if trees are our guides to connection?

Through the intertwining rings of science and spirit, this is the story of how Lindsay was summoned by trees, brought together to share their enduring wisdom—we each belong to this world, and it’s up to us to protect the whole of it. Heartwood conjures an invitation to go on a journey with trees; from strangers to kin because, as Lindsay lays out in detail, everything belongs, and trees in all their sentinel, entangled, alchemical generosity embody that kinship, defy domination and can help us both repair a lost relationship with the Earth and learn to embody mutuality, collectivity and care for the forest.

Combining scientific research from her PhD studies at Cambridge on interoceptive awareness, our body’s “eighth sense,” which she suggests is the sensuous language of the Earth, readers will be walked through a step‑by‑step wonder-filled process of creating an intimate and reciprocal relationship with the more than human world, while learning why remembering our birthright of belonging to nature is a central antidote to mitigating climate collapse.

This tender, lyrical work speaks directly to what is the missing piece at the heart of the unfolding environmental mega-crisis: the fact that our dissatisfaction, discontent and despair are core symptoms of being separated from nature—and shares exactly how to rediscover the medicine that is right under our feet.

Praise for Heartwood

What people are saying

As the world literally and figuratively burns, Branham isn't panicked or frozen. She is giving us a vibrant, vision-changing way to survive what's coming. She doesn't come with a sword, but a gentle invitation to learn to hear the wisdom of trees. If we follow her lead, we just might make it.

Jedidiah Jenkins

2x New York Times bestselling author of Like Streams to the Ocean, To Shake the Sleeping Self, Mother Nature

Heartwood is a radiant and deeply urgent book. Branham reminds us that healing—of our bodies, our spirits, and our planet—is not found in separation but in relationship. Through sharing her personal story and combining it with her intellectual rigor, she guides us to see how trees can not only be our kin but can also be our guides back to belonging.

Anna Malaika Tubbs

2x New York Times bestselling author of The Three Mothers and Erased

A wonderfully perceptive and generative book, filled with invitations to open our bodies and imaginations to the many gifts offered by trees. A powerful reminder, too, of the healing powers of trees for individuals and communities.

David George Haskell

Biologist and two-time Pulitzer finalist, author of Sounds Wild and Broken, The Songs of Trees, The Forest Unseen

With Heartwood, Lindsay Branham invites us to remember our deepest ties to the planet we call home, bringing us back to our bodies, asking us to recall our roots and the trees who long to guide us. Her instruction is both personal and researched, backed by scientific exploration and spiritual connection that is earthbound, practical and holistic.

Heartwood

I very much believe that how you do anything is how you do everything. Heartwood is a gift to us all to widen our hearts with more love for this suffering world.

Richard Rohr

2x New York Times bestselling author of The Universal Christ and The Tears of Things

With poetic tenderness, depthful knowledge, and embodied presence, Heartwood will guide readers to their inherent belonging, interconnectedness, and relationship with the living earth. In a landscape of forgetting, this book offers a remembrance and a homecoming toward our own nature and interwoven humanity.

Lisa Olivera

Author of Already Enough and When the Ache Remains

Lindsay's mesmerizing book is both a comfort and a call to action in a time of climate crisis. A map to guide us out of overwhelm and despair, and into a reciprocal relationship with the more-than-human world that is the missing piece in conversations about environmental activism.

Ruby Warrington

Author of Sober Curious and Women Without Kids

In this luminous love song to trees, Lindsay Branham transmutes science into poetry, converts the scholarly into the sacred, and engages language to point beyond itself to a place of profound silence our souls yearn for. Bold and dignified, intelligent and sensual, this book helped me fall in love with the world again.

Mirabai Starr

Author of Wild Mercy and Ordinary Mysticism

In Heartwood, Lindsay has crafted a narrative that paints nature as the center point of our healing. Woven together with a beautiful prosaic touch, she has magically connected the dots between our liberation and the centuries old knowledge rooted firmly in the mother of our existence: the trees.

Joél Leon

Author of the 2025 Gotham Book Prize nominated Everything and Nothing At Once

In mellifluous prose, embedded with sparkling glimpses of poetry, we encounter an interwoven discourse and guided meditation on trauma, chronic illness and autoimmunity, healing and recovery, and the rediscovery—the re-enchantment—of our relationship with nature. This beautifully written book is not to be missed!

Sylvestre Quevedo, MD, MPH

Research Physician, Berkeley Center for the Science of Psychedelics and Helen Wills Neuroscience Institute, UC Berkeley

In this luminous book, Lindsay Branham offers what so many are now yearning for—a way to come back into felt connection with the living world. Effortlessly combining scientific research, Buddhist practice, and indigenous wisdom, she unveils the remarkable discovery that enhancing our interoceptive sensitivity restores our ability to hear and understand the language of the land. It offers a realistic path, weaving us back into wholeness.

Brother Spirit

Plum Village

I received the invite to read and consider endorsing this book the day after my return from an Indigenous ceremony centering on sacred tree. I felt Spirit must be involved somehow, so I read the book and quickly realized Spirit indeed had connected us. With reverence and courage, Dr. Branham draws us back into the circle of life, where trees stand not as resources but as relations. Interweaving the rigor of doctoral research with the depth of personal healing, Dr. Branham calls us home with her passionate stories. Moreover, offering proven practices, she shows how the wisdom needed to restore balance in our lives and on Earth is already alive in the voices of the natural world.
