Book Description
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.

Book Description
Explores in detail the technology of harvesting and processing the grain, the important place of wild rice in Ojibway ceremony and legend, including the rich social life of the traditional rice camps, and the volatile issues of treaty rights. Wild rice has always been essential to life in the Upper Midwest and neighboring Canada. In this far-reaching book, Thomas Vennum Jr. uses travelers' narratives, historical and ethnological accounts, scientific data, historical and contemporary photographs and sketches, his own field work, and the words of Native people to examine the importance of this wild food to the Ojibway people. He details the technology of harvesting and processing, from seventeenth-century reports though modern mechanization. He explains the important place of wild rice in Ojibway ceremony and legend and depicts the rich social life of the traditional rice camps. And he reviews the volatile issues of treaty rights and litigations involving Indian problems in maintaining this traditional resource. A staple of the Ojibway diet and economy for centuries, wild rice has now become a gourmet food. With twentieth-century agricultural technology and paddy cultivation, white growers have virtually removed this important source of income from Indigenous hands. Nevertheless, the Ojibway continue to harvest and process rice each year. It remains a vital part of their social, cultural, and religious life.

Book Description
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.
