Download or read book Breeding Bird Communities in Aspen Forests of the Sub boreal Spruce dk Subzone in the Prince Rupert Forest Region written by Rosamund A. Pojar and published by Research Branch, Ministry of Forests. This book was released on 1995 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports a two-year study initiated to examine the diversity of bird communities in different seral stages of the aspen ecosystem at the western end of the dry cool subzone of the sub-boreal spruce zone of the Prince Rupert Forest Region, British Columbia. Breeding birds were chosen for the study since they tend to stay within a relatively confined area once in their territories and are hence easier to count. The study also had the objective of identifying management indicator species that could represent the diversity of most birds likely to be affected by aspen management. Birds were counted by a modified point count method for clearcuts, sapling aspen stands, mature aspen stands, old aspen stands with century-old trees, and mixed aspen-conifer stands. Data were analyzed using a detrended correspondence analysis ordination procedure, and habitat relationships of the 16 most abundant species were analyzed by multiple regression.

Download or read book Ecological Dynamics on Yellowstone s Northern Range written by National Research Council and published by National Academies Press. This book was released on 2002-02-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.

Download or read book Creating a Forestry for the 21st Century written by Kathryn A. Kohm and published by Island Press. This book was released on 1997 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, a sea change has occurred in the field of forestry. A vastly increased understanding of how ecological systems function has transformed the science from one focused on simplifying systems, producing wood, and managing at the stand-level to one concerned with understanding and managing complexity, providing a wide range of ecological goods and services, and managing across broad landscapes.Creating a Forestry for the 21st Century is an authoritative and multidisciplinary examination of the current state of forestry and its relation to the emergent field of ecosystem management. Drawing upon the expertise of top professionals in the field, it provides an up-to-date synthesis of principles of ecosystem management and their implications for forest policy. Leading scientists, including Malcolm Hunter, Jr., Bruce G. Marcot, James K. Agee, Thomas R. Crow, Robert J. Naiman, John C. Gordon, R.W. Behan, Steven L. Yaffee, and many others examine topics that are central to the future of forestry: new understandings of ecological processes and principles, from stand structure and function to disturbance processes and the movement of organisms across landscapes challenges to long-held assumptions: the rationale for clearcutting, the wisdom of short rotations, the exclusion of fire traditional tools in light of expanded goals for forest landscapes managing at larger spatial scales, including practical information and ideas for managing large landscapes over long time periods the economic, organizational, and political issues that are critical to implementing successful ecosystem management and developing institutions to transform knowledge into action Featuring a 16-page center section with color photographs that illustrate some of the best on-the-ground examples of ecosystem management from around the world, Creating a Forestry for the 21st Century is the definitive text on managing ecosystems. It provides a compelling case for thinking creatively beyond the bounds of traditional forest resource management, and will be essential reading for students; scientists working in state, federal, and private research institutions; public and private forest managers; staff members of environmental/conservation organizations; and policymakers.

Download or read book The Date Creek Silvicultural Systems Study in the Interior Cedar hemlock Forests of Northwestern British Columbia written by K. Dave Coates and published by British Columbia, Ministry of Forests, Research Program. This book was released on 1997 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Date Creek silvicultural systems study was one of several projects established in British Columbia in the early 1990s to examine alternatives to traditional clear-cut harvesting. The study comprises a multidisciplinary set of experiments that examines ecosystem processes and timber production in undisturbed, partially cut, and clear-cut stands within the transitional coastal-interior forests of north-western British Columbia. This report provides background information on the Date Creek study in three major sections. The first is an overview of the study area, its climate, soils, vegetation, and the experimental design and silvicultural treatments used in the research. The second section supplies detailed information on the research area (ecosystem mapping and soils) and the individual treatment units (ecosystems, soils, pre- and post-treatment stand structure). The final section outlines the objectives of individual experiments under way.
