This book reveals the benefits of describing and modeling trees as the combined surface areas of their stems, and provides a concise overview of the fundamental grounds for adopting such an approach. Anatomically speaking, trees are largely thin sheaths of living cells and it is this understanding that has sparked growing interest in the study of stem surface areas in trees and stands. An overview of publications on analytical methods for the dynamics and structure of forest stands based on stem surface area is also provided. The approach described here gives readers a chance to rethink some models that were popular for decades, while also offering a glance into future research. The application of a simple geometrical model of a forest stand has made it possible to reexamine a highly promising model, the self-thinning rule, which has been a subject of a protracted discussion for the past few decades. Further, the analysis presented here can serve as the basis for predicting forest stand increments, a topic that calls for further development.

Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.

In this book is summarized those management principles that should be valid in areas where forests continuously are used for production, where biodiversity aspects are important as well as economy and productivity, and where demands on soil status and water quality are set. Especially the very long-term aspects are emphasized, and it is shown how system model thinking is used to reach the goals. Biogeochemical aspects are put forward as they are very important in areas on poor bedrock with acid soils. Forest vitality and stress on trees are treated, as well as the importance of wildlife and their effects of browsing. The balance between social and recreational demands from the society and the economical needs of the landowner is of great concern. Experiences from a special area in South Sweden are presented.
