Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

The flood that affected a third of the United States during the summer of 1993 was the nation's worst, ranking as a once-in-300-years event. It severely tested national, state, and local systems for managing natural resources and for handling emergencies, illuminating both the strengths and weaknesses in existing methods of preparing for and dealing with massive prolonged flooding. Through detailed case studies, this volume diagnoses the social and economic impacts of the disaster, assessing how resource managers, flood forecasters, public institutions, the private sector, and millions of volunteers responded to it. The first comprehensive evaluation of the 1993 flood, this book examines the way in which floods are forecast and monitored, the effectiveness of existing recovery processes, and how the nation manages its floodplains. The volume concludes with recommendations for the future, in hope of better preparing the country for the next flood or other comparable disaster.

North America's Great Lakes country has experienced centuries of upheaval. Its landscapes are utterly changed from what they were five hundred years ago. The region's superabundant fish and wildlife and its magnificent forests and prairies astonished European newcomers who called it an earthly paradise but then ushered in an era of disease, warfare, resource depletion, and land development that transformed it forever. The Once and Future Great Lakes Country is a history of environmental change in the Great Lakes region, looking as far back as the last ice age, and also reflecting on modern trajectories of change, many of them positive. John Riley chronicles how the region serves as a continental crossroads, one that experienced massive declines in its wildlife and native plants in the centuries after European contact, and has begun to see increased nature protection and re-wilding in recent decades. Yet climate change, globalization, invasive species, and urban sprawl are today exerting new pressures on the region’s ecology. Covering a vast geography encompassing two Canadian provinces and nine American states, The Once and Future Great Lakes Country provides both a detailed ecological history and a broad panorama of this vast region. It blends the voices of early visitors with the hopes of citizens now.
