Forest trees constitute one of the major resources of the world and their utilization, either for structural purposes or for the materials which they yield, dates back to antiquity. Over the centuries, the exploitation of this resource has become progressively more sophisticated, and, in many parts of the world has led to the development of highly complex forest-based industries. The research and development work which led to these industrial uses fostered the formation of numerous technical societies and associations, which, through their meetings and publi cations, have facilitated communication and the exchange of ideas. Over the years, there have been numerous symposia devoted to wood and the many facets of its properties and utilization. However, rarely has the emphasis in such symposia been placed upon the living tree and the changes which it undergoes in relation to its ultimate utilization. Hence the Phytochemical Society of North America arranged the symposium, "The Structure, Biosynthesis, and Degradation of Wood", held at the University of British Columbia in August, 1976. the contributions to which form the basis of the present volume.
