“This book represents decades of detailed research by one of North America’s top ethnobiologists. Minnis draws on multiple sources to create this unique compendium of plants that humans have turned to during times of food scarcity. Critically important to peoples of the past, this knowledge may be just as important to future populations.”—Nancy J. Turner, author of Ancient Pathways, Ancestral Knowledge: Ethnobotany and Ecological Wisdom of Indigenous Peoples of Northwestern North America
