Download or read book National Forest Inventories Contributions to Forest Biodiversity Assessments written by Gherardo Chirici and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest biodiversity is crucial to the ecological, economic, and social well-being of earth’s civilisations. Unfortunately, however, forest biodiversity is threatened to a serious degree in nearly all countries. Therefore, many countries have agreed to be parties to international agreements focused on maintaining, restoring, and monitoring biodiversity; further, these countries have agreed to report to international bodies on forest biodiversity status and trends. NFIs are the primary source of large-scale information available for this purpose, but the large variety of definitions, protocols, sampling designs, and plot configurations used by NFIs makes comparable international reporting extremely difficult. This book presents the results of Working Group 3 of COST Action E43 in the development of harmonization techniques for common reporting of estimates of forest biodiversity indicators using NFI data. Harmonization tests were carried out on a large common data base containing raw NFI data from 13 European countries and the USA. With its collection of practical examples for the estimation of forest biodiversity indicators, it's a practical tool for anyone involved in forest inventories and in forest resource monitoring and management as well as for those involved in biodiversity assessment and reporting.

Book excerpt: Physical Limnology provides the physical, chemical, and biological information practitioners need to effectively manage inland waters. Physical processes in lakes are known to have significant influence on driving the biology, chemistry, and geology in aquatic environments. In addition to covering the current knowledge in the area of lake physics, this helpful guide also provides coverage of some of the latest challenges in physical limnology. Physical Limnology also covers the mathematical modeling necessary to make basic calculations related to what is happening in lakes. Authored by one of the recognized world leaders in the field Covers the latest physical, chemical, and biological process information, making the work accessible to the general limnologist , lake practitioner, or biologist Provides examples from the author's experience working with lakes around the world Features coverage of the latest challenges in physical limnology
Download or read book Insect Conservation Past Present and Prospects written by Tim R. New and published by Springer Science & Business Media. This book was released on 2012-03-14 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of interest and practice in insect conservation is summarised and traced through contributions from many of the leaders in the discipline, to provide the first broad global account of how insects have become incorporated into considerations of conservation. The essays collectively cover the genesis and development of insect conservation, emphasising its strong foundation within the northern temperate regions and the contrasts with much of the rest of the world. Major present-day scenarios are discussed, together with possible developments and priorities in insect conservation for the future.

Download or read book Hydrological and Biological Responses to Forest Practices written by John D. Stednick and published by Springer. This book was released on 2010-11-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

Download or read book Hydrologic Effects of a Changing Forest Landscape written by National Research Council and published by National Academies Press. This book was released on 2008-12-19 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the outputs of forests, water may be the most important. Streamflow from forests provides two-thirds of the nation's clean water supply. Removing forest cover accelerates the rate that precipitation becomes streamflow; therefore, in some areas, cutting trees causes a temporary increase in the volume of water flowing downstream. This effect has spurred political pressure to cut trees to increase water supply, especially in western states where population is rising. However, cutting trees for water gains is not sustainable: increases in flow rate and volume are typically short-lived, and the practice can ultimately degrade water quality and increase vulnerability to flooding. Forest hydrology, the study of how water flows through forests, can help illuminate the connections between forests and water, but it must advance if it is to deal with today's complexities, including climate change, wildfires, and changing patterns of development and ownership. This book identifies actions that scientists, forest and water managers, and citizens can take to help sustain water resources from forests.
Download or read book Effects of Forest Practices on Peak Flows and Consequent Channel Response written by Gordon Grant and published by . This book was released on 2008 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a state-of-the-science synthesis of the effects of forest harvest activities on peak flows and channel morphology in the Pacific Northwest, with a specific focus on western Oregon and Washington. We develop a database of relevant studies reporting peak flow data across rain-, transient-, and snow-dominated hydrologic zones, and provide a quantitative comparison of changes in peak flow across both a range of flows and forest practices. Increases in peak flows generally diminish with decreasing intensity of percentage of watershed harvested and lengthening recurrence intervals of flow. Watersheds located in the rain-dominated zone appear to be less sensitive to peak flow changes than those in the transient snow zone; insufficient data limit interpretations for the snow zone. Where present, peak flow effects on channel morphology should be confined to stream reaches where channel gradients are less than approximately 0.02 and streambeds are composed of gravel and finer material. We provide guidance as to how managers might evaluate the potential risk of peak flow increases based on factors such as presence of roads, watershed drainage efficiency, and specific management treatments employed. The magnitude of effects of forest harvest on peak flows in the Pacific Northwest, as represented by the data reported here, are relatively minor in comparison to other anthropogenic changes to streams and watersheds.
