The Great Lakes ecosystem is recognised by many as an international natural resource that has been altered by human activities and climate variability. These alterations have led to degraded water quality, diminished habitat, lower native fish and wildlife populations, and an altered ecosystem. In response, the federal governments of the United States and Canada and the state and provincial governments in the Great Lakes basin are implementing several restoration activities. These activities range from mitigating the harmful effects of toxic substances in lake waters to restoring fish habitat. This books provides the reader with a background on and issues of the Great Lakes restoration initiative, as well as the action plan for the years 2010-2014.
"Langston focuses on three ghost species in the Great Lakes watershed-woodland caribou, common loons, and lake sturgeon. Their traces are still present in DNA, small fragmented populations, or in lone individuals. We can still restore them, if we make the hard choices necessary for them to survive"--
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.
2022 NAUTILUS SILVER WINNER FOR LYRIC PROSE—In The Accidental Reef and Other Ecological Odysseys in the Great Lakes, Lynne Heasley illuminates an underwater world that, despite a ferocious industrial history, remains wondrous and worthy of care. From its first scene in a benighted Great Lakes river, where lake sturgeon thrash and spawn, this powerful book takes readers on journeys through the Great Lakes, alongside fish and fishers, scuba divers and scientists, toxic pollutants and threatened communities, oil pipelines and invasive species, Indigenous peoples and federal agencies. With dazzling illustrations from Glenn Wolff, the book helps us know the Great Lakes in new ways and grapple with the legacies and alternative futures that come from their abundance of natural wealth. Suffused with curiosity, empathy, and wit, The Accidental Reef will not fail to astonish and inspire.
Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.
This volume, cataloging and analyzing the current science on the state of Lake Michigan, is an important part of Great Lakes recovering science. It carries forward the singular contribution that the binational Great Lakes scientific community has made not only to restoring the Great Lakes but also to the world's body of knowledge about large lake ecology, the long-range transport of pollutants, and the importance of habitat in ensuring ecosystem health.
To maintain thriving, sustainable fisheries in the Laurentian Great Lakes, an understanding of the numerous and complex ecological, societal, economic, management, and policy issues surrounding them is critical. This incisive study provides a collaborative, interjurisdictional, and multi-use perspective that is shaped by the United states and Canada together as part of their shared governance of these waters. This book offers an informed look at the Great Lakes fisheries and their ecosystems, as the contributors examine both the threats they have faced and the valuable opportunities they provide for basin citizens and industries. Divided into four sections--the Great Lakes region, Great Lakes Fisheries, Fisheries case studies, and outlook for the Future--this is a valuable and up-to-date tool for students, researchers, policymakers, and managers alike.
