Available in PDF, EPUB and Kindle. Book excerpt: USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Download or read book Soil and Plant Analysis for Forest Ecosystem Characterization written by Daniel John Vogt and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-03-30 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an overview of physical, chemical and biological methods used to analyze soils and plant tissue using an ecosystem perspective. The current emphasis on climate change has recognized the importance of including soil carbon as part of our carbon budgets. Methods to assess soils must be ecosystem based if they are to have utility for policy makers and managers wanting to change soil carbon and nutrient pools. Most of the texts on soil analyis treat agriculture and not forest soils and these methods do not transfer readily to forests because of their different chemistry and physical properties. This manual presents methods for soil and plant analysis with the ecosystem level approach that will reduce the risk that poor management decisions will be made in forests. This manual was intended for the instructors that teach students soil and plant analyses; however it can also be used by the research laboratories and by environmental scientists. The laboratory procedures in this manual are outlined in easy-to-follow steps and frequently accompanied with examples of calculations, questions to answer, and also a blank data sheet to use. These methods used in this manual can be used on soil and plant tissues found in agricultural, horticulture, forestry, urban, and natural lands.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical analyses are an essential part of forest ecosystem monitoring activities. Harmonized, well-defined, and documented analytical methods are an important part of a laboratory Quality Control program and are essential to maximize spatial and temporal comparability of monitoring data. Different quality and data consistency checks, plausible ranges for analytical results, use of reference materials, and control charts are described for internal laboratory Quality Control. On the other side, coordinated ring tests among participating laboratories are an integral part of external Quality Control. Organization of ring tests, evaluation, and the benchmark with tolerable limits are described and specified. Results for water, foliage, and soil ring tests and the evaluation of quality indicators within the European forest ecosystem monitoring program are reported.
Download or read book Forest Monitoring written by Nathalie Cools and published by Elsevier Inc. Chapters. This book was released on 2013-03-16 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter describes methods for long-term forest soil monitoring from the field design, to the laboratory analytical methods, and through to the data compilation and validation. Soil monitoring comprises two main pillars: the soil characterization, including a detailed soil profile description and classification; and the assessment of the physical and chemical status of the soil layers. Composite samples are taken at fixed-depth intervals, mainly for chemical analyses. Soil bulk density and soil water retention characteristics are measured using undisturbed core samples, in contrast to the other variables. Specific sampling techniques are employed for forest floors, peat soils, and fine-textured mineral and stony soils. The recommended laboratory methods are predominantly based on International Organization for Standardization methods. Results from the second European forest soil survey are presented to demonstrate the usefulness and implementation of the described methods.

This book was released on 2016-04-19 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest management has evolved from a mercantilist view to a multi-functional one that integrates economic, social, and ecological aspects. However, the issue of sustainability is not yet resolved. Quantitative Techniques in Participatory Forest Management brings together global research in three areas of application: inventory of the forest variables that determine the main environmental indices, description and design of new environmental indices, and the application of sustainability indices for regional implementations. All these quantitative techniques create the basis for the development of scientific methodologies of participatory sustainable forest management.

This book was released on 2020-09-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.
Download or read book Soil Change Guide Procedures for Soil Survey and Resource Inventory written by U.S. Department of Agriculture and published by Lulu.com. This book was released on 2019-04-06 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many soil properties have changed and can change as a result of management, historical land use, or even natural factors, such as drought, interacting with land use. National soil survey databases currently include soil property information for the relatively static soil properties, such as texture, and also for properties affected by management, such as soil organic matter. The databases do not, however, distinguish the values of dynamic soil properties (e.g., organic matter, bulk density, infiltration rate) according to their land use, management system, ecological state, or plant community. ?Dynamic soil properties? as defined in this Guide are soil properties that change within the human time scale. Differences that may exist in these properties can affect the performance of the soil. Furthermore, some dynamic soil properties change very little in response to management and disturbances.

Available in PDF, EPUB and Kindle. Book excerpt: Soils and other resource programs in both public land management agencies and private industry are continually being adapted to the challenges of evolving knowledge and experience in the field of forestry. This dissertation explores new ways of thinking about and using soils information in forest planning and management, with a focus on Pacific Northwest lands. At the core of this work are the concepts of soil quality, in particular, the applications of inherent and dynamic soil quality. These soil quality concepts can be used as both a planning tool to improve our understanding and assessment of land-use decisions and as an assessment tool to evaluate the sustainability of different management practices. The result is two very different types of soil interpretations based on inherent and dynamic soil quality concepts which are applied at different times and for different purposes during forest planning and management. Forest planning soil interpretations that are based upon inherent soil quality are used primarily to make land use allocations and related decisions. These interpretations are applied up-front in the forest planning process and are based on the fact that different soils vary widely in their inherent capacity to perform various ecological and utilitarian functions. By both recognizing different soil types in the local landscape and understanding how those various soils naturally function, managers can use inherent soil interpretations to better match land management objectives to soil types that have a high capacity to meet those objectives. Matching soil potentials to the appropriate land management actions in this manner helps to assure management actions will be both attainable and sustainable over the long term. Soil interpretations that are based upon dynamic soil quality differ from those based upon inherent soil quality in that dynamic soil interpretations are primarily used to assess the sustainability of management practices. These interpretations identify different soils' resistance and resilience to disturbances and use soil-based indicators of key soil functions to make assessments of the effects of different disturbances. A conceptual "forest planning and management model" is presented that illustrates applications of these soil quality concepts in the forest planning process. Concepts and practical applications of the conceptual model are illustrated in current forest level planning projects within the US Forest Service (FS) Region 6. Soil disturbance monitoring was also conducted in recently managed areas and used to both provide a practical procedure for monitoring soil porosity changes and to present a case for updating current directives and guidelines for FS Region 6 Soil Quality Standards. It is my hope that this work will be of value to both soil scientists and other forest resource specialists and managers. Perhaps one of the more significant contributions that may come of this work is that it may help soil scientists and others to be inspired through a better understanding of the "value added" when soils information is considered in new and effective ways. It is also my hope that this work provides some of the practical ideas and tools necessary to take advantage of opportunities to apply knowledge of the soil resource in future forest planning and management.
