The inspiration for “Ethnobotany and Traditional Knowledge Preservation” arose from a deep recognition of the wisdom embedded in traditional cultures and their enduring relationship with the natural world particularly with plants. Across generations and geographies, communities have cultivated a profound understanding of the flora around them, not merely as resources, but as integral elements of their identity, spirituality, and survival. This knowledge carefully passed down through oral traditions, rituals, and lived experiences is now under threat. As modern development, climate change, and cultural homogenization accelerate, the urgency to document, protect, and revitalize traditional ecological knowledge has never been greater. Ethnobotany and Traditional Knowledge Preservation is both a scholarly exploration and a heartfelt tribute to those who continue to live in harmony with their environments, guided by inherited wisdom. Bringing together interdisciplinary perspectives from ethnobotany, anthropology, conservation, and indigenous studies, this volume aims to bridge the gap between scientific inquiry and community experience. We delve into diverse examples of plant use from healing and food sovereignty to spiritual and ceremonial practices and spotlight the stewards of this knowledge: the elders, healers, farmers, and forest dwellers whose voices are too often marginalized. The chapters that follow offer more than academic insight they offer stories of resilience, innovation, and respect. Our hope is that Ethnobotany and Traditional Knowledge Preservation not only informs but inspires a greater appreciation for the value of traditional knowledge in addressing today’s ecological and cultural challenges. In honoring these ancient practices, we also pave the way for a more inclusive and sustainable future. We extend our deepest gratitude to the knowledge holders, researchers, and communities who shared their time, trust, and teachings. May their wisdom continue to flourish and guide generations to come.
