Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive handbook on the seeds of trees and shrubs produced by the USDA Forest Service was USDA Misc. Pub. 654, Woody-Plant Seed Manual. The manuscript was ready for publication in 1941, but World War II delayed publication until 1948. The boom in tree planting in the 1950s and 1960s created a large demand for seeds and exposed the gaps in our knowledge concerning production and quality of seeds of woody plants in general. The 1974 Handbook proved to be very popular both in this country and abroad, leading to five printings and translations in several other languages. More than a quarter-century after its publication, however, numerous advances in tree seed technology have dictated that a new revision is needed; the result is the current volume. Part I contains information on how to get seeds and raise seedlings. Get Your Copy Now.

Available in PDF, EPUB and Kindle. Book excerpt: During the 4th International Consultation on Forest Genetics and Tree Building, held in 1998 in Beijing, China, leading scientists were invited to review past achievements, to redefine the role of forest genetics and breeding in contemporary forestry, and to set priorities for future research and development. On the basis of the invited presentations, the volume summarizes the state of knowledge in various fields, such as the impact of forest management and of changing environmental conditions on genetic resources, and the value of genetic markers as indicators for adaptational potential, as well as the tasks of conservation. Detailed reports from the different continents provide a comprehensive diagnosis of the global situation of forest genetics and tree breeding research. The book offers not only an overview of contemporary trends and expected future developments, but also identifies current main problems in funding and cooperation. It may prove therefore useful not only for scientists, university lecturers and advanced students in the field of forestry, ecology and conservation biology, but also for decision makers and managers in companies and conservation organizations.

This book was released on 2020-06-05 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid deforestation and depletion of genetic resources have made it essential that avenues be found whereby short-duration trees can be propagated and massed produced. Clonal agroforestry plantations provide this alternative to the use of natural forests. Agroforestry with Commercial Clonal Plantations in India provides complete scientific information on clonal technology applications for selection and cloning of candidate plus trees, development, field testing, final selection and deployment of genetically superior, high yielding and fast-growing clones of important tree species grown under agroforestry system. Clonal agroforestry plantations need to be supported with strong R & D and sound, efficient and timely extension services for the farmers. The book discusses in detail the establishment of modern largescale clonal plant production nurseries and improved silvicultural management of clonal agroforestry plantations of Eucalypts, Poplars, Casuarinas, and other species. Specific recommendations for further advancements in all areas related to tree improvement, development of new superior clones, holistic development of agroforestry and required policy reforms have been also provided.

Download or read book Genetic Diversity and Erosion in Plants written by M.R. Ahuja and published by Springer. This book was released on 2015-12-16 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation, urbanization, and land clearing through deforestation and brush fires. In order to conserve biodiversity in plants, it is important to targets three independent levels that include ecosystems, species and genes. Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. Chapters in this book are written by leading geneticists, molecular biologists and other specialists on relevant topics on genetic erosion and conservation genetic diversity in plants. This divisible set of two volumes deals with a broad spectrum of topics on genetic erosion, and approaches to biodiversity conservation in crop plants and trees. Volume 1 deals with indicators and prevention of genetic erosion, while volume 2 covers genetic diversity and erosion in a number of plants species. These two volumes will also be useful to botanists, biotechnologists, environmentalists, policy makers, conservationists, and NGOs working to manage genetic erosion and biodiversity.

This book was released on 2010-07-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1 Plantation forests and biodiversity: Oxymoron or opportunity? Forests form the natural vegetation over much of the Earth’s land, and they are critical for the survival of innumerable organisms. The ongoing loss of natural forests, which in some regions may have taken many millennia to develop, is one of the main reasons for the decline of biodiversity. Preventing the further destruction of forests and protecting species and ecosystems within forests have become central issues for environmental agencies, forest managers, and gove- ments. In this di?cult task science has an important role in informing policy and management as to how to go about this. So how do industrial and other pl- tation forests ?t into this? Plantation forests, comprised of rows of planted trees that may be destined for pulp or sawmills after only a few years of growth, appear to have little to c- tribute to the conservation of biodiversity. Yet there is more to this than meets the eye (of the casual observer), and there are indeed numerous opportunities, and often untapped potential, for biodiversity conservation in plantation forestry. With plantation forests expanding at a rate of approximately three million hectares per year, it is crucial to understand how plantations can make a positive contribution to biodiversity conservation and how the potentially negative impacts of this land use can be minimised. That is the topic of this book.

Download or read book Dendroecology written by Mariano M. Amoroso and published by Springer. This book was released on 2017-12-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.

Download or read book New Forests written by Sadanandan Nambiar and published by CSIRO PUBLISHING. This book was released on 2005-11-10 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no question that the timber industry needs to adopt sustainable practices that ensure a future for the industry. This book goes well beyond simply growing commercial tree plantations for wood production. It explores new forests that can supply environmental services such as salinity mitigation and carbon sequestration together with commercial wood production in an environment beyond the boundaries of traditional forestry. New Forests targets agricultural landscapes affected by salinity and which generally have rainfall less than 650 mm per year. The book addresses vital issues such as where tree planting might best be pursued, what species and technologies should be used for establishment and later management, how productivity can be improved, what mix of environmental services and commercial goods is optimum, and whether the likely net benefits justify the change in land use and requisite investment. While the book is focussed on the low-rainfall, agricultural, inland zone of the Murray-Darling Basin wherever possible the scope of most chapters has been expanded to synthesise generic information applicable to other regions in Australia and elsewhere. The authors provide a comprehensive account of all the issues relevant to the development of these new forests, covering soils, the bio-physical environment, water use and irrigation strategies - including the use of wastewater, silviculture, pests and diseases, wood quality and products, and economics and policy implications.

Download or read book Forest Conservation Genetics written by Andrew Young and published by CSIRO PUBLISHING. This book was released on 2000-07-24 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest management must be sustainable not only in ecological, economic and social, but also genetic terms. Many forest managers are advocating and developing management strategies that give priority to conserving genetic diversity within production systems, or that recognise the importance of genetic considerations in achieving sustainable management. Forest Conservation Genetics draws together much previously uncollected information relevant to managing and conserving forests. The content emphasises the importance of conserving genetic diversity in achieving sustainable management. Each chapter is written by a leading expert and has been peer reviewed. Readers without a background in genetics will find the logical sequence of topics allows easy understanding of the principles involved and how those principles may impact on day-to-day forest planning and management decisions. The book is primarily aimed at undergraduate students of biology, ecology, forestry, and graduate students of forest genetics, resource management policy and/or conservation biology. It will prove useful for those teaching courses in these fields and as such help to increase the awareness of genetic factors in conservation and sustainable management, in both temperate and tropical regions.

Download or read book Commercial Forest Plantations on Saline Lands written by Marcia Lambert and published by CSIRO PUBLISHING. This book was released on 2000-04-01 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the information that will allow users to recover salt-degraded land with selected plantation timbers and ultimately to make a profit. The authors have drawn on their own experiences plus material from Australia, India, California and Israel where similar saline soil conditions occur. The authors also bring their extensive work in forest biotechnology to the book. The primary species of interest are in the genus Eucalyptus although other species, notably conifers, are referred to. Issues involved in defining the characteristics of sites where plantations may be established and their special management requirements are discussed. Options are presented for the selection and development of appropriate genotypes plus associated management practices. Monitoring of plantations is shown to be a vital management issue. The work includes a chapter on environmental benefits which will broaden the appeal beyond forest managers, extension officers and students of forestry to companies which produce CO2 but which have no prior knowledge of forestry.

Download or read book Tree Breeding Principles and Strategies written by G. Namkoong and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become apparent, during discussions with students and colleagues in forest genetics, that a universal concern is the achievement of diverse goals of forestry from fiber production in industrial as well as farm forests to conserving forest ecosystems. Although we generally have several breeding methods available and several species to breed, we seek to satisfy multiple-use goals on diverse sites by management techniques that at best can only partially control edaphic environmental variation. The dominant approach, which was agriculturally motivated, has involved inten sive effort with complicated breeding plans on single species for uniform adaptability and single-product plantations. However, this is obviously neither the only, nor necessarily the best, solution for the genetic management of tree species, and thus our intent in this volume is to develop ways to achieve multiple objectives in tree breeding. We include an array of breeding plans from simple iterated designs to sets of multiple populations capable of using gene actions for different traits in different environments for uncertain futures. The presentation is organized around the development of breeding from single-to multiple-option plans, from single to multiple traits, from single to mUltiple environ ments, and from single to multiple populations. However, it is not a complete "How To" book, and includes neither exercises nor instructions on data handling. It also does not include discussion of all modes of reproduction and inheritance encountered in plants.

Download or read book Clonal Forestry II written by Mulkh-Raj Ahuja and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provided here are both underlying theory and recent results concerning the propagation and use of clones in research and in production forestry. State-of-the-art science and case histories treating production, testing, multiplication and deployment of clones are presented. Agroforestry, urban forestry and christmas-tree farming are covered, along with more traditional multiple-use forestry and high-intensity forestry for biomass, wood and fiber production. Clonal forestry is contrasted to the more recent developments of "family forestry", and the classical tree-improvement approach relying on seed-orchards. The history of clonal forestry is covered with reviews of several centuries experience with Sugi in Japan and poplars in Europe. The impacts and use of clones in the contexts of genetic conservation and biodiversity are discussed, as are the laws and regulations affecting clonal production and deployment.

Download or read book Population Genetics of Forest Trees written by W.T. Adams and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.
