Book Description
Excerpt from Bias and Precision of the Barr and Stroud Dendrometer Under Field Conditions Direct measurements of tree volume are usually obtained by measuring felled trees. Many foresters are reluctant to fell trees that may not be utilized, especially valuable species or crop trees under rotation age (winters In addition to the loss of volume and growing stock, leaving felled trees provides breeding places for certain insects and increases fire hazard in the forest. Also, trees measured may not be the property of the party or agency conducting the survey. In other cases, such trees might be located on permanent sample plots that cannot be destroyed.

Book Description
This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Book Description
This established text is the only introduction to qualitative research methodologies in the field of library and information management. Its extensive coverage encompasses all aspects of qualitative research work from conception to completion, and all types of study in a variety of settings from multi-site projects to data organization. The book features many case studies and examples, and offers a comprehensive manual of practice designed for LIS professionals. This new edition has been thoroughly revised and includes three new chapters. It has been updated to take account of the substantial growth in the amount and quality of web-based information relevant to qualitative research methods and practice, and the many developments in software applications and resources. The authors have identified a clear need for a new chapter on the evaluation of existing research, as a gateway into new research for information professionals. The final chapter, 'Human Resources In Knowledge Management', takes the form of a model case study, and is an 'ideal' qualitative investigation in an information setting. It exemplifies many of the approaches to qualitative research discussed in earlier chapters. Readership: Directed primarily at the beginner researcher, this book also offers a practical refresher in this important area for the more experienced researcher. It is a useful tool for all practitioners and researchers in information organizations, whether libraries, archives, knowledge management centres, record management centres, or any other type of information service provider.

Book Description
Complete guidelines to developing and maintaining the most effective, environment-friendly irrigation systems for golf courses Golf Course Irrigation offers valuable insight on the design, installation, management, and maintenance of irrigation systems-the most important management tool used on today's golf courses. Without manufacturers' bias, this useful resource provides hands-on guidance to the highest quality irrigation systems, including specifications and applications of the best pump stations, controllers, sprinkler heads, nozzles, valves, sensors, and other components that make the difference in top-quality irrigation systems. Typically regarded as significant users of water, golf courses are under increasing scrutiny by governmental and environmental groups, making it essential that the up-to-date information found here-on such topics as water supply, plant irrigation requirements, application uniformity, and construction management-be at the fingertips of every golf course professional. While fostering the best playing conditions, these systems conserve water and energy with such technology as low-pressure heads and controls that use "if/then" logic to automatically adjust to changing conditions, which can improve playability while saving money. Golf Course Irrigation is a practical tool to help golf course architects, builders, superintendents, irrigation consultants, designers, and installers to improve aesthetics and playing conditions in the face of diminishing natural resources. It is also an informative reference for golf course owners, developers, local officials, students, and fans of the game.

Book Description
Climate changes, particularly warming trends, have been recorded around the globe. For many countries, these changes in climate have become evident through insect epidemics (e.g., Mountain Pine Beetle epidemic in Western Canada, bark beetle in secondary spruce forests in Central Europe), water shortages and intense forest fires in the Mediterranean countries (e.g., 2005 droughts in Spain), and unusual storm activities (e.g., the 2004 South-East Asia Tsunami). Climate changes are expected to impact vegetation as manifested by changes in vegetation extent, migration of species, tree species composition, growth rates, and mortality. The International Panel on Climate Change (IPCC) has included discussions on how forests may be impacted, and how they may be used to mitigate the impacts of changes in climate, to possibly slow the rate of change. This book provides current scientific information on the biological and economical impacts of climate changes in forest environments, as well as information on how forest management activities might mitigate these impacts, particularly through carbon sequestration. Case studies from a wide geographic range are presented. This information is beneficial to managers and researchers interested in climate change and impacts upon forest environments and economic activities. This volume, which forms part of Springer’s book series Managing Forest Ecosystems, presents state-of-the-art research results, visions and theories, as well as specific methods for sustainable forest management in changing climatic conditions.
