This book was released on 1992-05-31 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional Ecology of Woodlands is firmly based on the factors which govern the composition of woodland communities, but goes on to explore the dynamics of interactions between various ecosystem components. This is an authoritative text on the functioning of forest ecosystems, which will also assist readers to reach informed decisions about issues such as the greenhouse effect, acid precipitation, the greening of cities and agroforestry.

Book excerpt: In this book, an ornithologist and a forester have combined their skills to try and tease out the real facts behind the various arguments on forestry. The conflict between forestry and nature conservation has become a major environmental issue in Britain in the 1980s. The planting of large tracts of land with exotic conifers and the resulting disturbance of existing plant and animal communities has polarized the debate, each camp believing that it has the most rational view. But the interactions involved are complex. Which bird species are really threatened? How can we judge the relative value of bird species ousted by plantations and the new species which colonize them? How can the need for forest products be reconciled with the demands of conservationists? This fascinating book tackles these issues in a forthright manner. It represents a significant step towards achieving the sort of prudent land planning that will really improve our beleaguered countryside. Jacket painting by Philip Snow. Foreword by David Bellamy.

Available in PDF, EPUB and Kindle. Book excerpt: As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

Download or read book Habitat Creation and Repair written by O. L. Gilbert and published by . This book was released on 1998 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Responding to concerns about the environment, landscape managers and developers are using extensive naturalistic plantings to restore habitats degraded by building, development, or overuse. This book is the definitive guide to habitat creation and repair; it includes discussions of ethics, theory, and general principles, along with the practical details of designing habitats for wildlife. The authors, who have been working and teaching in the field for many years, draw on a wealth of practical experience--as well as an in-depth knowledge of the widely scattered literature--to provide an authoritative and accessible account of this rapidly developing subject. From coastal and freshwater ecosystems to mountains, forest, and grasslands, the book contains specific chapters on most of the major habitat types. The authors give advice on deciding when habitat creation is the correct path to follow, and then cover all steps from site survey through to the final design and actual realization of the scheme. A useful resource for professionals, this volume is ideal as a textbook for advanced undergraduate and graduate courses in ecology, landscape architecture, resource management, and environmental science.

Download or read book Forest Decline and Ozone written by Heinrich Sandermann and published by Springer Science & Business Media. This book was released on 1996-12-03 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book arose in 1993, after the Free State of Bavaria through its Bayrisches Staatsministerium rur Landesentwicklung und Umweltfragen (Bavarian Ministry of Regional Development and the Environment) decided to discontinue both the Bavarian project management (PBWU) for forest decline research and the multidisciplinary field research on the Wank Mountain in the Alps near Garmisch. Forest decline through the action of ozone and other photooxidants was a main topic of the supported re search in the Alps and will be a topic of new investigations in the Bavarian Forest. Many interesting results were obtained, but the researchers involved have not had sufficient time to allow reliable conclusions to be drawn. It was therefore decided to ask inter national experts for contributions in order to summarize the best available evidence of a possible link between ozone and forest decline - a topic which has been studied in the USA since the late 1950s and in Europe since the early 1980s. The original idea of Waldsterben as an irreversible large-scale dieback of forests in Germany was soon recognized to be wrong (Forschungsbeirat 1989). However, the new criteria used for the official German and European damage inventories (loss or yel lowing of needles or leaves, tree morphology) indicate that per sistently high percentages of damaged spruce and pine remain, and there is an increasing percentage of damaged beech and oak, with a high proportion of biotic disease (Forschungsbeirat 1989; UN-ECE 1995).
