A complete guide to the theoretical and practical aspects of vegetation analysis. Two chapters are devoted to actual case studies, and should enable the reader to understand exactly how a wide range of analytical methods can be applied to data acquired in the field. The first two chapters discuss the purpose of vegetation analysis and the statistical approaches involved. Strategies employed in the planning and execution of field work are thoroughly considered, and chapter three looks at the fundamental principles which underlie the numerical techniques used in working out results. Other chapters explain the methodology applied in processing the numerical information. This latter section deals with such topics as classifications, ordination, and correlation between the vegetation and its environment, and is designed to facilitate more accurate ecological interpretation of data. Assuming an elementary knowledge of statistics, this book provides a unified, detailed guide to vegetation analysis.
