Available in PDF, EPUB and Kindle. Book excerpt: After nearly 60 years, with descriptions of more than 270 species and almost 200 illustrations, Textbook of Dendrology continues to remain a top resource for taxonomic and silvicultural information on North American trees. In this new edition, material throughout the text has been updated and expanded to provide current information on tree sizes, damaging diseases and insect pest, economic uses, and silvics. Because of growing concern for the environment, it is even more necessary for students to know and understand the importance of conservation. Many of these issues are incorporated throughout the book.

Book excerpt: Preface: With the large number of books now available featureing North American trees, the launching of another on this subject merits perhaps some explanation. Most present tree manuals fall into one of two classes: (1) encyclopedic, such as Sargent's monumental "Silva of North America," later condensed into one volume, which has been adapted by nearly every writer of tree books since it first appeared; and (2) local, as exemplified by the many excellent state and regional manuals. Nearly all these publications have been written from the botanical or taxonomic standpoint and in general treat each species in the same detail. It is obviously impossible for a beginning student in forestry to gain an adequate knowledge of more than a few of the thousand tree species native to this continent. Rather, it is desirable only to cover as many groups (genera) as possible, and to illustrate these with the species of greatest importance to forestry. Such a treatment, accompanied by adequate photographic halftones, has not been available to date, and the authors hope that the present book will fill this need. The native coniferous genera have all been included because of their relative importance, and fewer numbers; but several families, and many genera species of the broadleaved trees have been omitted. It is felt that students of forestry should first know well the commercial species of North America, and then become familiar with the lesser important trees and shrubs of the locality where they may find themselves practicing forestry. The latter must usually be done by the student himself with the aid of a local tree manual. If he has fully appreciated generic characteristics during his training in dendrology, this should not be a difficult procedure. Because this book is not comprhensive for any one portion of the country, it seems best to omit detailed keys and to use instead tables covering family and generic characters. Our experience shows that basic information is more readily assimilated in this form. The does not mean that keys are not of primary importance, and considerable time should be spent with them in identifying local material. The authors will greatly appreciate having any errors called to their attention and will also welcome comments or criticism from those using the book in teaching or otherwise. Most of the photographs were taken with one of the modern miniature cameras whose remarkable depth of focus has made possible many otherwise unattainable pictures. William M. Harlow, Ellwood S.

Download or read book Contested Nature written by Steven R. Brechin and published by State University of New York Press. This book was released on 2012-02-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the international conservation movement protect biological diversity, while at the same time safeguarding the rights and fulfilling the needs of people, particularly the poor? Contested Nature argues that to be successful in the long-term, social justice and biological conservation must go hand in hand. The protection of nature is a complex social enterprise, and much more a process of politics, and of human organization, than ecology. Although this political complexity is recognized by practitioners, it rarely enters into the problem analyses that inform conservation policy. Structured around conceptual chapters and supporting case studies that examine the politics of conservation in specific contexts, the book shows that pursuing social justice enhances biodiversity conservation rather than diminishing it, and that the fate of local peoples and that of conservation are completely intertwined.
Download or read book Communities and Forests written by Robert G. Lee and published by . This book was released on 2005 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communities and Forests offers a timely view of the changing face of forests and forestry in North America today. In examining interactions between people and forests, the book shows that forests are as much a social institution as they are a biological resource. The book begins with an investigation of the historical and sociological foundations of community-based forest management. Chapters in the second section highlight the diverse issues surrounding community forestry, specifically the conflicts between the management of public forestlands and the interests of various stakeholders in using forests as a public good. The final section examines urban forestry, focusing on both the importance of forestry in urban settings and the demographic shifts that have brought people with urban values and lifestyles to rural, forested settings.

Available in PDF, EPUB and Kindle. Book excerpt: “A mesmerizing read.... A literary work of high distinction.” —William Grimes, New York Times This “gripping and poignant memoir” (New York Times Book Review) draws us into the intersections of everyday life and Communist power from the first days of “Liberation” in 1949 through the post-Mao era. The son of a professional family, Kang Zhengguo is a free spirit, drawn to literature. In Mao’s China, these innocuous circumstances expose him at age twenty to a fierce struggle session, expulsion from university, and a four-year term of hard labor. So begins his long stay in the prison-camp system. He finally escapes the Chinese gulag by forfeiting his identity: at age twenty-eight he is adopted by an aging bachelor in a peasant village, which enables him to start a new life.

This book was released on 2002 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate broadleaved trees grow in very different ecosystems in the northern and southern hemispheres, but are also found extensively in many tropical and subtropical mountain areas. A wide range of non-wood products are derived from temperate broadleaved trees, and their description is organized in this volume according to the part of the tree from which they are obtained (whole tree, foliage, flowers, etc.). This information is presented in order to raise awareness on, and assist in identifying, opportunities for the management and production of non-wood products from temperate broadleaved trees. The intended audience of this publication ranges from interest groups in the forest, agriculture and rural development sectors to conservation agencies in developed and developing countries.

Download or read book Data Analysis in Community and Landscape Ecology written by R. H. Jongman and published by Cambridge University Press. This book was released on 1995-03-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological data has several special properties: the presence or absence of species on a semi-quantitative abundance scale; non-linear relationships between species and environmental factors; and high inter-correlations among species and among environmental variables. The analysis of such data is important to the interpretation of relationships within plant and animal communities and with their environments. In this corrected version of Data Analysis in Community and Landscape Ecology, without using complex mathematics, the contributors demonstrate the methods that have proven most useful, with examples, exercises and case-studies. Chapters explain in an elementary way powerful data analysis techniques such as logic regression, canonical correspondence analysis, and kriging.
