Book excerpt: “Only God can make a tree,” wrote Joyce Kilmer in one of the most celebrated of poems. In Tree: A Life Story, authors David Suzuki and Wayne Grady extend that celebration in a “biography” of this extraordinary — and extraordinarily important — organism. A story that spans a millennium and includes a cast of millions but focuses on a single tree, a Douglas fir, Tree describes in poetic detail the organism’s modest origins that begin with a dramatic burst of millions of microscopic grains of pollen. The authors recount the amazing characteristics of the species, how they reproduce and how they receive from and offer nourishment to generations of other plants and animals. The tree’s pivotal role in making life possible for the creatures around it — including human beings — is lovingly explored. The richly detailed text and Robert Bateman’s original art pay tribute to this ubiquitous organism that is too often taken for granted.

Available in PDF, EPUB and Kindle. Book excerpt: Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

This book was released on 2017-11-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first truly modern book solely devoted to seed reproduction of forest trees-from flowering to establishment, with emphasis on the interaction of environment with physiological processes. Focus is on seed function in natural settings and the application of information to natural regeneration of forests. This easy-to-read text addresses important principles and provides in-depth coverage of existing literature. Presentation of the information is organized to allow for a natural development of the main theme with full explanations of such important components as seed production, dispersal and germination, as well as the integral parts played by water, temperature, light, chemicals, animals, pathogens and aging. A highly useful book for investigators, practitioners or students.

Available in PDF, EPUB and Kindle. Book excerpt: This book integrates class, environmental, and political analysis to uncover 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 the technological and managerial structures of worker and resource exploitation from the perspective of current trends in labour process research. Rajala argues that operators sought to neutralize the variable forest environment by emulating the factory model of work organization. The introduction of steam-powered overhead logging methods provided industry with a rudimentary factory regime by 1930, accompanied by productivity gains and diminished workplace autonomy for loggers. After a Depression-inspired turn to selective logging with caterpillar tractors timber capital continued its refinement of clearcutting technologies in the post-war period, achieving complete mechanization of yarding with the automatic grapple. Driviing this process of innovation was a concept of industrial efficiency that responded to changing environmental conditions, product and labour markets, but sought to advance operators' class interests by routinizing production. The managerial component of the factory regime took shape in accordance with the principles of the early 20th century scientific management movement. Requiring expertise in the organization of an expanded, technologically sophisticated exploitation process, operators presided over the establishment of logging engineering programs in the region's universities. Graduates introduced rational planning procedures to coastal logging, contributing to a rate of deforestation that generated a corporate call for technical forestry expertise after 1930. Industrial foresters then emerged from the universities to provide firms with data needed for long-range investment decisions in land acquisition and management. Part II constitutes an environmental and political history of clearcutting. This reconstructs the process of scientific research concenring the factory regime's impact on the ecology of the Douglas fir forest, assessing how knowledge was utitized in the regulation of cutting practices. Analysis of business-government relations in British Columbia, Washington and Oregon suggests that the reliance of those client states on revenues generated by timber capital enouraged a pattern of regulation that served corporate rather than social and ecological ends.
