For anyone who cherishes the wild, grapples with environmental grief, or seeks inspiration to keep moving forward, this memoir is both a solace and a call to action.

Drawing on a lifetime spent in the wilds of western Canada’s national parks and years of conservation work, Van Tighem reflects on a career spent protecting the natural world and the emotional toll of witnessing its decline. Freed from bureaucratic constraints after retirement, he turned to writing, activism, and politics, driven by a sense of duty to the landscapes and species he loves. But alongside his commitment to action came profound grief and the pressing question: how do we find hope amid environmental loss?

Van Tighem’s reflections are anchored in the “understory” of his life—the hidden, tangled layers beneath the surface of his experiences. Like the shadowed depths of a forest, these memories and insights are both beautiful and unsettling, revealing the challenges and rewards of engaging fully with the world around us. With unflinching honesty, he examines the joys of connection, the pain of loss, and the enduring value of caring deeply, even when the odds feel insurmountable.

Written with the lyricism of a naturalist and the candour of a seasoned storyteller, Understory invites readers to confront their own relationships with nature and consider how they, too, can find purpose and hope in uncertain times.
