Book Description
"Concern over the ongoing conversion of wetlands is growing. Information on the location, extent, and quality of remaining wetlands is needed to assist in developing future policy and management actions aimed at retaining wetland values. In addition, knowledge of wetland conversion rates and trends is important in assessing the current status of wetlands"--Abstract.

Book Description
An understanding of environmental gradients (physical, chemical, hydrological, and biological) is a prerequisite to the accurate delineation of wetland boundaries. Presenting the wide-ranging views of academicians, environmentalists, policy makers, consultants, planners, engineers, hydrologists, biologists, geochemists, ecologists, and conservationists, Wetlands: Environmental Gradients, Boundaries, and Buffers focuses on current topics and research related to wetland delineation; summarizes the main issues of concern; and provides recommendations on research needs. In addition to integrating the most important research and theoretical aspects, this book includes a strong prescriptive component, providing practicing professionals with specific guidance on defining the true dimensions of a wetland area.

Book Description
The colony that became Ontario arose almost spontaneously out of the confusion and uncertainty following the American Revolution, as a quickly chosen refuge for some 10,000 Loyalists who had to leave their former homes. After the War of 1812 settlers began to spread throughout the inter-lake peninsula that was to become southern Ontario and by the middle of the nineteenth century expansion had led to a diversifying agriculture and an increasingly open farming landscape that replaced a mature forest ecosystem. The scale of the change from forest to cropland profoundly affected what had been for many decades a rich environment for life forms, from large herbivores down to microscopic creatures. In Making Ontario David Wood shows that the most effective agent of change in the first century of Ontario's development was not the locomotive but settlers' attempts to change the forest into agricultural land. Wood traces the various threads that went into creating a successful farming colony while documenting the sacrifice of the forest ecosystem to the demands of progress, progress that prepared the ground for the railway. Making Ontario provides a detailed focus on environmental modification at a time of great changes. It is liberally illustrated with analytical maps based on archival research.

Book Description
Forested wetlands are a major component of northern landscapes, important both for their ecological functions and their socioeconomic values. Historically, these lands have been used for timber and fiber products, hunting, fishing, trapping, food gathering, and recreation. There are many questions about the use and management of these lands in the future, particularly with respect to forest products, hydrology and water quality, plant and wildlife ecology, landscape dynamics, and wetland restoration. Northern Forested Wetlands: Ecology and Management provides a synthesis of current research and literature. It examines the status, distribution, and use of these wetland resources. The book focuses on understanding the role of wetlands in the landscape and on how to manage these wetlands and sustain their important functions. This is a primary reference text for the study and management of northern forested wetlands, providing a forum for information discovered by researchers and managers from many nations.
