The reintroduction of rare and endangered species to their natural habitat is one of the emerging tools of ecosystem management. Yet despite hundreds of ongoing projects, the biological underpinnings of such activity are poorly understood, and important questions remain. This book examines those questions, including: the strategic and legal context for rare plant restoration; the biology of restoration; and use and misuse of mitigation in rare plant conservation. Model guidelines are presented for the reintroduction of endangered plants and not only unifies concepts in the field of restoration, but also fills significant technical and policy gaps.
