The most up-to-date, comprehensive resource on silviculture that covers the range of topics and issues facing today’s foresters and resource professionals The tenth edition of the classic work, The Practice of Silviculture: Applied Forest Ecology, includes the most current information and the results of research on the many issues that are relevant to forests and forestry. The text covers such timely topics as biofuels and intensive timber production, ecosystem and landscape scale management of public lands, ecosystem services, surface drinking water supplies, urban and community greenspace, forest carbon, fire and climate, and much more. In recent years, silvicultural systems have become ...
Much of the world's forested land is dominated by mixed-species stands. Understanding the complex structure and dynamics of these mixtures is a necessary step in the process of formulating appropriate silvicultural systems for their management. David M. Smith, Professor Emeritus of Silviculture at Yale University, has devoted much of his career to the study of the structure, development, and silvicultural treatment of these kinds of stands. This volume is presented by Professor Smith's collegues to honor the contributions he has made to the field. It contains both reviews of past work and results of current studies of mixed stands: topics range from analysis of forest dynamics in unmanaged stands to studies of silvicultural systems applied to mixtures, with examples drawn from boreal, temperate, and tropical regions. Much of the work stresses the importance of understanding the characteristic growth patterns of individual species within mixed stands, and how species interactions shape developmental patterns.
This burgeoning interdisciplinary interest in “intellectual property” has also expanded beyond the conventional categories of patent, copyright, and trademark to encompass a diverse array of topics ranging from traditional knowledge to international trade.
During the Green Revolution in many developing countries, agroforestry systems tended to reflect modern agricultural systems by their intensive use of fertilizers, pesticides, and site modifications to fit the desired crop. Since the 1980's, agroforestry has learned from traditional indigenous systems to work more closely with the fertility of marginal lands through the use of less intensive cultivation and fallow periods. True to its title, this volume provides a silvicultural framework for thinking about the design and practice of agroforestry systems. Unlike many general agroforestry books, The Silvicultural Basis for Agroforestry Systems emphasizes research and thoughts from a forestry perspective rather than an agricultural one. Many of the examples used in this reference are based on the ecological theory of forests that concern the competition for resources of plant-plant and plant-animal mixtures. This guide also uses the knowledge gained about the temporal and spatial dynamic and productivity of forests as the basis for silvicultural applications in agroforestry systems. The Silvicultural Basis for Agroforestry Systems contains three parts:
Fire, both inevitable and ubiquitous, plays a crucial role in North American ecosystems. But as necessary as fire is to maintaining healthy ecosystems, it threatens human lives and livelihoods in unacceptable ways. This volume explores the rich yet largely uncharted terrain at the intersection of fire policy, fire science, and fire management in order to find better ways of addressing this pressing dilemma. Written in clear language, it will help scientists, policy makers, and the general public, especially residents of fire-prone areas, better understand where we are today in regard to coping with wildfires, how we got here, and where we need to go. Drawing on abundant historical and analytic information to shed new light on current controversies, Living with Fire offers a dynamic new paradigm for coping with fire that recognizes its critical environmental role. The book also tells how we can rebuild the important ecological and political processes that are necessary for finding better ways to cope with fire and with other complex policy dilemmas.

This study shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to growing two or more crops together and how the approach can improve agricultural yields.
Comprehensive book describes the various growth patterns of forests. The purpose is to help silviculturalists and forest managers understand and anticipate how forests grow and respond to intentional manipulations and natural disasters.
