This introductory chapter lays the foundations for a thorough investigation of Lantana camara, an invasive species that is recognized as a worldwide paradox. It results in multiple contradictions, as an invasive species of ecological concern, yet a potentially useful source for bioprospecting. It proposes how the book is designed and leads into the following chapters that discuss Lantana camara’s morphology and taxonomy, its rapid invasion ecology and significant environmental and social impacts, and complex agricultural affects while simultaneously introducing the history and ongoing ethnobotanical relevance of the plant, including its phytochemistry, traditional medicinal use, and potential value-added products. The chapter emphasizes perhaps the most important aspect of exploring Lantana camara for useful products, which is equally relevant for the health of the environment and society, toxicology, and safety. Ultimately, it establishes the book’s overarching goal: that of fostering balanced understanding to convert Lantana camara challenges into sustainable resource use challenges and subsequent management opportunities.
