This book was released on 2012-07-09 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.

Available in PDF, EPUB and Kindle. Book excerpt: This report examines public perspectives on disturbance-based management conducted in the central Cascade Range in Oregon as part of the Blue River Landscape Strategy. A mail survey to local residents was used to describe the publics understanding of this form of management, identify perceived associated risks and potential barriers to implementation, and the overall level of support for disturbance-based practices. Findings suggest the public generally supports the disturbance-based concept, particularly ecological benefits, but many individuals are still uncertain about details and are withholding judgment until they see the outcomes of implementation. Support is highly correlated with citizens past interaction with local managers. Major concerns involve the amount of timber harvesting necessary to achieve objectives and the possibility that changing national politics may influence the consistency of agency policies toward disturbance-based management.

Available in PDF, EPUB and Kindle. Book excerpt: The Changing Mile, originally published in 1965, was a benchmark in ecological studies, demonstrating the prevalence of change in a seemingly changeless place. Photographs made throughout the Sonoran Desert region in the late 1800s and early 1900s were juxtaposed with photographs of the same locations taken many decades later. The nearly one hundred pairs of images revealed that climate has played a strong role in initiating many changes in the region. This new book updates the classic by adding recent photographs to the original pairs, providing another three decades of data and showing even more clearly the extent of change across the landscape. During these same three decades, abundant information about climatic variability, land use, and plant ecology has accumulated, making it possible to determine causes of change with more confidence. Using nearly two hundred additional triplicate sets of unpublished photographs, The Changing Mile Revisited utilizes repeat photographs selected from almost three hundred stations located in southern Arizona, in the Pinacate region of Mexico, and along the coast of the Gulf of California. Coarse photogrammetric analysis of this enlarged photographic set shows the varied response of the region's major plant species to the forces of change. The images show vegetation across the entire region at sites ranging in elevation from sea level to a mile above sea level. Some sites are truly arid, while others are located above the desert in grassland and woodland. Common names are used for most plants and animals (with Latin equivalents in endnotes) to make the book more accessible to non-technical readers. The original Changing Mile was based upon a unique set of data that allowed the authors to evaluate the extent and magnitude of vegetation change in a large geographic region. By extending the original landmark study, The Changing Mile Revisited will remain an indispensable reference for all concerned with the fragile desert environment.

Download or read book Accelerating Development of Late-successional Conditions in Young Managed Douglas-fir Stands written by Steven Lee Garman and published by . This book was released on 2003 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this simulation study was to provide information for defining thinning regimes for young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the Central Cascades Adaptive Management Area, located in west-central Oregon. Specifically, this study used the ZELIG. PNW (3.0) gap model to evaluate effects of experimental thinning treatments on the development of late-successional attributes and on extracted merchantable volume. Sixty-four thinning treatments were simulated for four rotation intervals (260, 180, 100, and 80 years) starting with a 40-year-old managed Douglas-fir stand. The amount of time for five late successional attributes to reach defined threshold levels, long-term developmental trends of these attributes, and amount of extracted merchantable volume were recorded for each treatment. Stand conditions of selected treatments were used in a subsequent harvest rotation in which 64 additional experimental thinning treatments were applied and evaluated. A total of 1,744 thinning treatments was evaluated in this study. Results of this study confirm previous recommendations for accelerating development of late-successional attributes in young managed stands. Additionally, results show the potential for a range of thinning treatments to attain late-successional conditions in about the same amount of time, but with different tradeoffs in terms of merchantable volume and long-term stand conditions. In general, heavy thinning of existing stands at ages 40 and 60 years promoted rapid development of large boles, vertical diversity, and tree-species diversity, but provided the least amount of extracted volume and required artificial creation of dead wood. Treatments that retained more than 40 percent of the original overstory and thinned to 99 trees per hectare at age 60 delayed attainment of late-successional conditions by 10 to 30 years but provided 12 to 20 percent more extracted volume, resulted in higher levels of most late-successional attributes at the end of a rotation, and required less artificial creation of dead wood. Treatments providing the fastest development of late-successional conditions in subsequent rotations varied with the amount of canopy cover retained at the end of the first rotation. For stands starting with ÃÃY30 percent canopy cover, delaying the first commercial thin for 40 years promoted the most rapid development of vertical structure and shadetolerant stems. Lower canopy-retention levels required heavy or light thins in subsequent entries, depending on the rotation interval, for rapid development of late-successional attributes.

Download or read book Livestock in a Changing Landscape, Volume 1 written by Henning Steinfeld and published by Island Press. This book was released on 2013-03-06 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. Over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. Livestock in a Changing Landscape offers a comprehensive examination of these important and far-reaching trends. The books are an outgrowth of a collaborative effort involving international nongovernmental organizations including the United Nations Food and Agriculture Organization (UN FAO), the International Livestock Research Institute (ILRI), the Swiss College of Agriculture (SHL), the French Agricultural Research Centre for International Development (CIRAD), and the Scientific Committee for Problems of the Environment (SCOPE). Volume 1 examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses. Volume 2 explores needs and draws experience from region-specific contexts and detailed case studies. The case studies describe how drivers and consequences of change play out in specific geographical areas, and how public and private responses are shaped and implemented. Together, the volumes present new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production, and represent an essential resource for policy makers, industry managers, and academics involved with this issue.
