Voices for the Watershed is a unique look at the singular and ecologically inter-connected region of the Great Lakes-St Lawrence watershed, including the headwater and upland regions. With contributions from experts from the United States, Quebec, and Ontario, this book offers an accessible introduction to the issues affecting the quality of our most essential and precious of natural resources - clean, fresh water - from headwater regions downstream to the Great lakes, the St Lawrence river, and ultimately the watershed's outflow to the sea. With thoughtful words and evocative photography, Voices for the Watershed promotes understanding and examines ecological problems, describing positive environmental actions and projects as well as ongoing concerns over the effects of pollution on wildlife and human health. The underlying themes throughout are that the drainage basins and ecosystems are under siege - from reckless land use decisions, soil erosion, acid rain, and massive habitat destruction - but that the situation is not hopeless. The authors feel strongly that education about the environmental threats - in the classroom and public forums - is essential to effecting positive change, and that conservation actions by citizen groups and individuals can be a driving force in effecting substantial reforms regarding environmental legislation and practices. Voices for the Watershed is an eye-opening look at not only the problems but possible solutions to help protect and preserve this resilient natural resource on which so many depend.

Drained by a half-dozen major watersheds, cut by a network of deep ravines and fronting on a Great Lake, Toronto is dominated by water. Like most cities, though, Toronto has mismanaged its water, from the decades-long transformation of the city's creeks into sewersheds to the alteration of Toronto's waterfront. Recently, the trend of fettering Toronto's water and putting it underground has been countered by persistent citizen-led efforts to recall and restore the city's surface water. In HTO: Toronto's Water from Lake Iroquois to Lost Rivers to Low-flow Toilets, 30 contributors examine the ever-changing interplay between nature and culture, and call into question the city's past, present and future engagement with water.

Historically, the flow of sediment in the Missouri River has been as important as the flow of water for a variety of river functions. The sediment has helped form a dynamic network of islands, sandbars, and floodplains, and provided habitats for native species. Further downstream, sediment transported by the Missouri and Mississippi Rivers has helped build and sustain the coastal wetlands of the Mississippi River delta. The construction of dams and river bank control structures on the Missouri River and its tributaries, however, has markedly reduced the volume of sediment transported by the river. These projects have had several ecological impacts, most notably on some native fish and bird species that depended on habitats and landforms created by sediment flow. Missouri River Planning describes the historic role of sediment in the Missouri River, evaluates current habitat restoration strategies, and discusses possible sediment management alternatives. The book finds that a better understanding of the processes of sediment transport, erosion, and deposition in the Missouri River will be useful in furthering river management objectives, such as protection of endangered species and development of water quality standards.

In metropolitan areas across the country, you can hear the laments over the loss of green space to new subdivisions and strip malls. But some city residents have taken unprecedented measures to protect their open land, and a growing movement seeks not only to preserve these lands but to link them in green corridors. Many land-use and urban planning professionals, along with landscape architects and environmental advocates, have joined in efforts to preserve natural areas. MetroGreen answers their call for a deeper exploration of the latest thinking and newest practices in this growing conservation field. In ten case studies of U.S. and Canadian cities paired for comparative analysis-Toronto and Chicago, Calgary and Denver, and Vancouver and Portland among them-Erickson looks closely at the motivations and objectives for connecting open spaces across metropolitan areas. She documents how open-space networks have been successfully created and protected, while also highlighting the critical human and ecological benefits of connectivity. MetroGreen's unique focus on several cities rather than a single urban area offers a perspective on the political, economic, cultural, and environmental conditions that affect open-space planning and the outcomes of its implementation.
