Available in PDF, EPUB and Kindle. Book excerpt: This book integrates class, environmental, and political analysis touncover the history of clearcutting in the Douglas fir forests of B.C.,Washington, and Oregon between 1880 and 1965. Part I focuses on the mode of production, analyzing thetechnological and managerial structures of worker and resourceexploitation from the perspective of current trends in labour processresearch. Rajala argues that operators sought to neutralize thevariable forest environment by emulating the factory model of workorganization. The introduction of steam-powered overhead loggingmethods provided industry with a rudimentary factory regime by 1930,accompanied by productivity gains and diminished workplace autonomy forloggers. After a Depression-inspired turn to selective logging withcaterpillar tractors timber capital continued its refinement ofclearcutting technologies in the post-war period, achieving completemechanization of yarding with the automatic grapple. Driviing thisprocess of innovation was a concept of industrial efficiency thatresponded to changing environmental conditions, product and labourmarkets, but sought to advance operators' class interests byroutinizing production. The managerial component of the factory regimetook shape in accordance with the principles of the early 20th centuryscientific management movement. Requiring expertise in the organizationof an expanded, technologically sophisticated exploitation process,operators presided over the establishment of logging engineeringprograms in the region's universities. Graduates introducedrational planning procedures to coastal logging, contributing to a rateof deforestation that generated a corporate call for technical forestryexpertise after 1930. Industrial foresters then emerged from theuniversities to provide firms with data needed for long-rangeinvestment decisions in land acquisition and management. Part II constitutes an environmental and political history ofclearcutting. This reconstructs the process of scientific researchconcenring the factory regime's impact on the ecology of theDouglas fir forest, assessing how knowledge was utitized in theregulation of cutting practices. Analysis of business-governmentrelations in British Columbia, Washington and Oregon suggests that thereliance of those client states on revenues generated by timber capitalenouraged a pattern of regulation that served corporate rather thansocial and ecological ends.

Available in PDF, EPUB and Kindle. Book excerpt: This study has two central concerns: the state of human health in forests, and the causal links between forests and human health. Within this framework, we consider four issues related to tropical forests and human health. First, we discuss forest foods, emphasizing the forest as a food-producing habitat, human dependence on forest foods, the nutritional contributions of such foods, and nutrition-related problems that affect forest peoples. Our second topic is disease and other health problems. In addition to the major problems—HIV/AIDS, malaria, Ebola and mercury poisoning—we address some 20 other tropical diseases and health problems related to forests. The third topic is medicinal products. We review the biophysical properties of medicinal species and consider related indigenous knowledge, human uses of medicinal forest products, the serious threats to forest sustainability, and the roles of traditional healers, with a discussion of the benefits of forest medicines and conflicts over their distribution. Our fourth and final topic is the cultural interpretations of human health found among forest peoples, including holistic world views that impinge on health and indigenous knowledge. The Occasional Paper concludes with some observations about the current state of our knowledge, its utility and shortcomings, and our suggestions for future research.

Available in PDF, EPUB and Kindle. Book excerpt: S2Two even-age management systems, progressive strip cutting and block clearcutting, have been studied since 1970 on small watersheds at the Hubbard Brook Experimental Forest, New Hampshire. In the strip cutting, all merchantable trees were harvested in a series of three strips over 4 years (1970-74). In the block clearcutting, all trees were harvested in a single operation in 1970. This paper contrasts progressive strip cutting and block clearcutting for the 10-year period after initiation of harvest in terms of hydrologic response, erosion losses, stream water ions, nutrient leaching, nutrient removals in harvested products, and natural regeneration of vegetation.S3.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts Includes management policies and their influence at the local, national and international levels
