Super Sitka for the 90s by Great Britain. Forestry Commission Pdf
Over 50 per cent of current planting of upland forest in the UK is Sitka spruce. Major areas of research on this species has sought to increase growth rates and timber yields, mainly through making genetically improved planting stock available to the forest grower. This publication is comprised of edited presentations made at a meeting in Elgin in 1990. Each paper addresses a separate issue relevant to the development of one of the most important species in upland forestry at the present time.
Ecology and Management of Sitka Spruce by N. Merle Peterson,Patrick Martin Pdf
Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

Geographic Variation in Forest Trees by Maria Morgenstern Pdf
Geographic Variation in Forest Trees is the first book to examine this subject from a world-wide perspective. The author discusses population genetic theory and genetic systems of native North American tree species as they interact with environments in the major climatic regions in the world. He then demonstrates how this knowledge is used to guide seed zoning and seed transfer in silviculture, basing much of his discussion on models developed in Scandinavia and North America. In the final chapter, the author addresses the issue of genetic conservation -- a subject of great concern in the face of accelerated forest destruction, industrial pollution, and climatic change. This comprehensive, well-researched book makes a significant contribution to the knowledge of one of our most important renewable natural resources.
Plantation Silviculture in Europe by Peter Savill,Julian Evans,Daniel Auclair,Jan Falck Pdf
Plantation Silviculture in Europe provides an up-to-date, succinct, and comprehensive overview of current European plantation forestry practices. Recognising that plantation silviculture today is no longer largely a question of how to grow large-scale industrial plantations, the authors have included chapters describing other, more diverse reasons for establishing trees. Forestry practices are set in the context of the science behind them and their environmental, social and policy frameworks. Concise and clear, this will be essential reading for forestry students and professionals alike. - ;As pressures to preserve natural forest resources have increased, plantation forestry and its study have gained in importance. Plantation Silviculture in Europe is an up-to-date, timely, and comprehensive exploration of the principles that underlie the planting and maintaining of forest resources. Based on the excellent reception of Savill and Evans' Plantation Silviculture in Temperate Regions (OUP, 1986), which was largely UK-based, the inclusion of two European authors ensures that the scope of this new book extends across the entire continent. Plantation Silviculture in Europe provides a thorough overview of the central aspects of conventional plantation forestry, covering site preparation, choice of species, establishment and maintenance, nutrition, spacing, thinning and pruning, and protection. In addition, it acknowledges the changing emphasis and increasing diversity of contemporary forestry, and includes chapters on community woodlands, urban forests, plantings for amenity and sport, and energy crops. Throughout, an attempt is made to set practices in the context of the ecological and biological forest processes which underpin them. Plantation Silviculture also incorporates discussion of the many environmental, social and policy issues that surround forestry today. Concise and clearly written, this will be essential reading for graduate and undergraduate forestry students and forestry professionals alike. Likely to become the standard text throughout Europe, it also contains much material of relevance to foresters in North America, East Asia, and Australasia. -
Biology of Adventitious Root Formation by Tim D. Davis,Bruce E. Haissig Pdf
Charles E. Hess Department of Environmental Horticulture University of California Davis, CA 95616 Research in the biology of adventitious root formation has a special place in science. It provides an excellent forum in which to pursue fundamental research on the regulation of plant growth and development. At the same time the results of the research have been quickly applied by commercial plant propagators, agronomists, foresters and horticulturists (see the chapter by Kovar and Kuchenbuch, by Ritchie, and by Davies and coworkers in this volume). In an era when there is great interest in speeding technology transfer, the experiences gained in research in adventitious root formation may provide useful examples for other areas of science. Interaction between the fundamental and the applied have been and continue to be facilitated by the establishment, in 1951, of the Plant Propagators' Society, which has evolved into the International Plant Propagators' Society, with active programs in six regions around the world. It is a unique organization which brings together researchers in universities, botanical gardens and arboreta, and commercial plant propagators. In this synergistic environment new knowledge is rapidly transferred and new ideas for fundamental research evolve from the presentations and discussions by experienced plant propagators. In the past 50 years, based on research related to the biology of adventitious root formation, advances in plant propagation have been made on two major fronts.

Cultural Turns/Geographical Turns by Simon Naylor,James Ryan,Ian Cook,David Crouch Pdf
Introduces undergraduates to the key debates regarding space and culture and the key theoretical arguments which guide cultural geographical work. This book addresses the impact, significance, and characteristics of the 'cultural turn' in contemporary geography. It focuses on the development of the cultural geography subdiscipline and on what has made it a peculiar and unique realm of study. It demonstrates the importance of culture in the development of debates in other subdisciplines within geography and beyond. In line with these previous themes, the significance of space in the production of cultural values and expressions is also developed. Along with its timely examination of the health of the cultural geographical subdiscipline, this book is to be valued for its analysis of the impact of cultural theory on studies elsewhere in geography and of ideas of space and spatiality elsewhere in the social sciences.
Cultural Procedures for Propagation of Rooted Cuttings of Sitka Spruce, Western Hemlock, and Douglas-fir in British Columbia by Bevin G. Wigmore Pdf
The use of rooted cuttings is explored as a means of bulking-up genetically improved families of Sitka spruce, western hemlock, and Douglas-fir for reforestation. The number of propagules produced from a small quantity of seed can be multiplied by taking cuttings from seedling stock plants. All methods are developed for 1-year-old cutting production in containers for consistency with most operational seedling production in British Columbia. This report describes cultural techniques for growing stock plants and rooted cuttings of Sitka spruce, western hemlock, and Douglas-fir, based on 3 years of nursery research and observations. It is concluded that 1-year container cut-ting production is technically feasible for Sitka spruce and western hemlock, but plagiotropism problems could not be overcome for the production of 1-year-old cuttings of Douglas-fir. A discussion of plagiotropism is included.
