The reintroduction of rare and endangered species to their natural habitat is one of emerging tools of ecosystem management. Yet despite hundreds of ongoing projects, the biological underpinnings of such activity are poorly understood, and important questions remain. Restoring Diversity provides biological, policy, and regulatory foundations for successful restoration of rare plants. Topics considered include the strategic and legal context for rare plant restoration, the biology of restoration, use (and misuse) of mitigation in rare plant conservation, and case studies from across the United States. Restoring Diversity presents model guidelines for the reintroduction of endangered plants - guidelines that incorporate ideas contained in the book's chapters with the wide-ranging experience of experts in the field. It is a pathbreaking work that not only unifies concepts in the field of restoration, but also fills significant technical and policy gaps and provides operational tools for successful restorations.
