"This is a forest measurements textbook written for field technicians. Silvicultural applications and illustrations are provided to demonstrate the relevance of the measurements. Special “technique tips” for each skill are intended to help increase data collection accuracy and confidence. These include how to avoid common pitfalls, effective short cuts, and essentials for recording field data correctly. The emphasis is on elementary skills; it is not intended to be a timber cruising guide"--BC Campus website.

Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

The third volume of the collected works of Mihaly Csikszentmihalyi covers his work on the application of flow in areas that go beyond the field of leisure where the concept was first applied. Based on his personal experience with schooling and learning, as well as that of many others and contrary to what Cicero claimed, Csikszentmihalyi arrived at the conclusion that instead of taking pride in making the roots of knowledge as bitter as possible, we should try to make them sweeter. Just as flow became a popular and useful concept in voluntary activities, it could likewise be applied in education with the end result of young people being more likely to continue learning not just because they have to but because they want to. This volume brings together a number of articles in which Csikszentmihalyi develops ideas about how to make education and more generally the process of learning to live a good life, more enjoyable. Since theory is the mother of good practice, the first eleven chapters are devoted to theoretical reflections. Some are general and explore what it means to be a human being, what it means to be a person, when we look at life from the perspective of flow. Others are more narrowly focused on such topics as consumption, education, teaching and learning. They help laypeople reflect how they can arrange their lives in such a way as to leave a small ecological footprint while getting the most enjoyment. The second section of the volume contains a dozen empirical articles on similar topics. They deal with the development of identity and self-worth; with the formation of goals and motivation; with loneliness and family life.
