Book excerpt: This paper first describes the nature & importance of wetlands in the forested regions of Canada and the forestry uses of wetlands. It then reviews the potential impacts of forestry operations on wetland ecosystems, including operations on wetland sites, upland operations near wetlands, draining treed wetlands for forestry, and the installation of forest roads that cross wetlands. Finally, measures to prevent or reduce those impacts are presented, with reference to experience in Canada and the United States.
Download or read book Northern Forested Wetlands Ecology and Management written by Carl C. Trettin and published by Routledge. This book was released on 2018-12-19 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Canada Alberta Wetlands Drainage and Improvement for Forestry Program written by Graham Robin Hillman and published by . This book was released on 1990 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1985, a wetland drainage and improvement for forestry program was instituted under the Canada-Alberta Forest Resource Development Agreement to determine the effects of drainage on tree growth, ground vegetation, soils, peat, and local hydrology. Three experimental areas were chosen and portions of each drained in 1986 and 1987. Data were collected from drained and undrained portions. Additional data were collected from a treed swamp near Fort McMurray that was subjected to different drainage treatments between 1975 and 1980. The intent, in this case, was to obtain an interim estimate of tree growth rates until sufficient time has elapsed to obtain estimates from permanent sample plots on the experimental areas. Results showed that the average depth to groundwater table after drainage was between 37 and 90 cm and varied with ditch spacing. The corresponding drops in water table levels were between 17 and 78 cm. The test areas with 30-m ditch spacings appeared to be overdrained. Stream water quality data from one site only have been interpreted so far. They show that drainage had little effect on measured physical and chemical stream water quality during low flows. Further analyses are required to determine the effects of drainage on peak flows. Initial results from the three experimental areas indicate that drainage has resulted in reduced ground vegetation cover (mosses, sedges and other herbs) and vigor. Lowering the water table on the swamp near Fort McMurray resulted in sigificant increases in height, diameter and volume of 30-year-old black spruce (Picea mariana). The increase in growth of black spruce was accompanied by an equally impressive growth of alder (Alnus crispa), willow (Salix spp.), birch (Betula pumila), aspen (Populus tremuloides) and balsam poplar (E. balsamifera)."--Page iii.

Download or read book Wetlands of the World I Inventory Ecology and Management written by Dennis F. Whigham and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.
Download or read book Conservation Biology Principles for Forested Landscapes written by Joan Voller and published by UBC Press. This book was released on 2011-11-01 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to provide information to those who wish to interact with the landbase in an ecologically sustainable manner. Practitioners charged with the administration of land-based programs in industry and government will find the information presented useful. It should also be a resource for many community groups involved in land-use decision-making. Humans continue to use forests and make decisions about land use without perfect information. Conservation Biology Principles for Forested Landscapes is intended to enable the improvement of planning and decison-making processes by providing ecological information on issues of forest use. Current approaches are not working. Where information exists on new, ecologically sustainable approaches, practitioners should switch. Where the information on a better approach is not yet available, practitioners should replace the current, inappropriate approach with a variety of flexible ones that offer the opportunity to change with new knowledge.

Download or read book Peatland Forestry written by Eero Paavilainen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a review and synthesis of boreal mire ecosystems including peat soil properties, mire hydrology, carbon and nutrient cycling, and classification of mire sites. The emphasis, however, is on peatland forests as a renewable natural resource. The approach originated in northern Europe, because there, especially in Finland, operational scale forest drainage has a long tradition based on research aiming to maintain and increase wood production on peatlands. Whenever relevant, a closer look is also given to other countries in Europe, Canada, and the USA. The results of recent studies on different environmental effects of peatland forestry are also discussed in detail.
Download or read book Causal Factors for Wetland Management and Restoration A Concise Guide written by Paul A. Keddy and published by Springer Nature. This book was released on 2023-03-11 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents 12 effective methods to manage wetlands for conservation. It offers a tool box of causal factors that can be used to protect and restore wetlands to enhance biological diversity and other functions. Each causal factor is introduced, briefly explained, and then illuminated with selected examples from around the world. The book provides a prioritized shopping list of methods for protecting and restoring wetlands. The three first and most important causal factors are flooding, fertility, and natural disturbance. Then nine other causal factors are introduced, including herbivory, sedimentation, roads, invasive species, and coarse woody debris. Each causal factor is carefully linked to the scientific literature and explained using the author’s own experience. The same list of 12 causal factors applies around the world—whether you are managing a temperate zone floodplain, a tropical peatland, a freshwater marsh, or a coastal mangrove swamp. Instead of hiring an expensive team of consultants, or pouring through hundreds of scientific papers, here is one concise guide to methods that can be immediately applied to benefit any wetland. Professor Paul Keddy has spent more than 50 years studying wetlands, and writing and lecturing about the environmental factors that control them. He has published more than 150 scholarly papers, and won multiple scientific prizes. His book Wetland Ecology is widely used to teach the principles of wetland science. Causal Factors for Wetland Management: A Concise Guide has a much simpler message: how to protect and enhance wetlands. In this concise guide, he has condensed a lifetime of experience into just 12 principles. The book is aimed at all people who protect or restore wetlands: park managers, wildlife biologists, landscape architects, engineers, environmental consultants, environmental agencies, conservation authorities, and NGOs—as well as landowners and concerned citizens. Causal Factors for Wetland Management: A Concise Guide is essential reading for anyone who cares for wetlands and wild places.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.
