Download or read book A Goal Oriented Approach to Forest Landscape Restoration written by John Stanturf and published by Springer Science & Business Media. This book was released on 2012-12-05 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: While restoration ecology has traditionally aimed to re-create some putative more ‘natural’ ecological state, forest landscape restoration (FLR) has emerged over the last decade as an approach aimed more at restoring natural functions, while focusing on meeting human needs. With a view to exploring the practical potential of this approach, this book draws together a team of experts from the natural and social sciences to discuss its success so far in addressing critical issues such as biodiversity, ecological function, and human livelihoods. Applying principles of landscape ecology, restoration ecology, planning theory and conflict management, the book presents a series of case studies which document the approach, and discusses how the approach can help with priority setting for the future. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

Download or read book Acid Waters in Wales written by R.W. Edwards and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.

It combines theory with a series of regional case studies to show how different aspects of forestry play out according to the landscape and historical context of the local area.

Download or read book British Rust Fungi written by Malcolm Wilson and published by Cambridge University Press. This book was released on 2011-06-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: W. B. Grove's British Rust Funghi, first published by Cambridge University Press in 1913, had long been the standard work on the subject. But it had grown increasingly obsolete in the light of the intensive research devoted to the group. As early as 1938, Dr Wilson, who was reader in Mycology at Edinburg University, was encouraged to prepare a new edition. Since then it became clear that what was needed was not a revision but an entirely new book. This was three-quarters complete in 1960, when Dr Wilson's illness and death again brought it to a halt. His colleague Dr Douglas Henderson then undertook full responsibility, completing the text and redrawing all the figures. This book was published in 1966 and is now being reissued. It covers all the species of Uredinales or Rust Fungi known in Britain at the time of publication and takes into account extensive research.

Download or read book Landscape Economics written by Colin Price and published by Springer. This book was released on 2017-10-12 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This revised and expanded edition of Colin Price's seminal publication provides a richly comprehensive and up-to-date coverage of landscape economics, a subject which has until now been addressed only in limited aspects. Although much of the book's discussion is based upon natural resources and environmental economics, the author presents a wide and integrative view, drawing from aesthetic, psychological, social and political perspectives and applying a critical use of economic concepts and challenges to different schools of thought on the landscape. This new edition includes new ideas and critiques on environmental valuation; more focused critiques of stated preference methods, political alternatives to economic valuation, and of the rationale of discounting future values; and, new evaluative techniques, particularly price premia for products with a landscape provenance. For those interested in the theoretical aspects of aesthetic valuation, and for those who seek solutions to practical problems of aesthetic conservation, amelioration and enhancement, this new edition gives an overview of evaluative techniques, of their potential problems and of possible solutions. The updates are a major contribution to the growing literature in the field.

Download or read book Environmental Ethics and Policy Making written by Mikael Stenmark and published by Routledge. This book was released on 2017-03-02 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental issues raise crucial questions. What should we value? What is our place in nature? What kind of life should we live? How should we interact with other living things? Environmental management and policy-making is ultimately based on answers to these and similar questions, but do we need a new ethics to be able overcome the environmental crisis we face? This book addresses these important questions and explores the values that decision-makers often presuppose in their environmental policy-making. Examining the content of the ethics of sustainable development that the UN and the world’s governments want us to embrace, this book examines alternatives to this kind of ethics, and the differences in basic values that these make in practice. Offering a detailed analysis of the ethics that lie behind current policy-making as it is expressed in documents such as Agenda 21 and the Rio Declaration, this unique contribution to the field of environmental studies shows how different environmental ethical theories support different goals of environmental management and generate different policies when it comes to population growth, agriculture, and preservation and management of wilderness areas and endangered species. Mikael Stenmark concludes that policy-makers must take more seriously the value assumptions and conflicts connected to environmental issues, and state explicitly on what values their own proposals and decisions are based and why these should be accepted. Those studying environmental issues or environmental philosophy will find this accessible text invaluable in presenting a clear understanding of environmental ethics and contemporary applications and policies.
