Clearcutting the Pacific Rain Forest

Book Description
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.
Forests and Human Health

Book Description
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.

Clearcutting Affects Stream Chemistry in the White Mountains of New Hampshire

Category : Clearcutting

Pages : 16
Book Description
S2Clearcutting of northern hardwood forests in New Hampshire resulted in accelerated loss of dissolved nutrients to streams similar to that shown in experimental studies at Hubbard Brook. Stream water samples were collected during 4 years from nine watersheds that had been completely clearcut and from five nearby reference watersheds that were uncut. Differences in stream chemistry between clearcut and reference watersheds were greatest during the second year after cutting. During the 4 years of the study, specific conductance of the reference streams ranged from 20 to 30 [mu] S/cm; average pH ranged from 5.0 to 5.7; nitrate ranged from less than 0.1 to about 4.0 mg/l; calcium from 1.0 to 3.0 mg/l; ammonium from less than 0.01 to 0.05 mg/l; magnesium from 0.2 to 0.8 mg/l; sodium from 0.6 to 1.6 mg/l; potassium from 0.1 to 0.7 mg/l; sulfate from 3.0 to 8.0 mg/l; and chloride from 0.3 to 0.6 mg/l. During the second year after clearcutting, specific conductance of streams draining the cuts ranged from 22 to 68 [mu] S/cm; average pH ranged from 5.1 to 6.0; nitrate ranged from 1.4 to 27.3 mg/l; calcium from 1.4 to 6.7 (ng/l; ammonium from less than 0.01 to 0.05 mg/l; magnesium from 0.3 to 1.4 mg/l; sodium from 0.8 to 3.0 mg/l; potassium from 0.1 to 1.5 mg/l; sulfate from 2.1 to 6.3 mg/l; and chloride from 0.4 to 0.9 mg/l. During the first year after cutting, streams from the cuts were more acidic than those from the reference streams; however, they were less acidic by the end of the second year. Concentrations of most ions in streams from clearcuts approached reference levels by the end of the fourth year after clearcutting, though streams from clearcuts remained less acidic by nearly a whole pH unit, sulfate remained depressed, and potassium remained elevated. During the 4 years following cutting, stream exports from cut sites exceeded those from reference sites by 57 kg/ha for inorganic nitrogen, 61 kg/ha for calcium, and 15 kg/ha for potassium.S3.
