Douglas-fir: The Genus Pseudotsuga

Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the tree species most widely distributed outside its natural range. The species has been introduced to Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir is an accepted and integral part of forest management in many countries because of its economic importance and its reputation as a species that may be able to deal with climate change. This book provides an overview of research activities and findings that highlight unique aspects of Douglas-fir physiology, genetics, and other related issues. It begins with the evolutionary history and distribution of Douglas-fir and provides a detailed description of introductions of Douglas-fir to other countries, including information about initial plantings, provenance trials, and genetic tree improvement activities. The sections about life history, drawn from extensive research and teaching experiences, include detailed descriptions of flowering, seeds, root, and seedling physiology, followed by sections about mycorrhizae and insects, diseases, and other biotic factors. It discusses research that demonstrates the some unique aspects of Douglas-fir physiology, for example: (1) Douglas-fir has an annual growth cycle that includes a cold period in the late fall or early winter. Failure to experience these low temperatures results in a substantial loss of vigor; (2) The reproductive system of the stem is stimulated by material from the roots; and (3) The root system plays a supportive role. Nutrient and moisture uptake are mediated by mycorrhizae. This book is intended as a resource for everyone interested in understanding the opportunities and challenges of managing Douglas-fir in a variety of regions and settings. It provides information for historians and social scientists trying to understand forestry trends, researchers, educators, and managers who look for detailed information in areas such as genetics and regeneration practices, and all others interested in the beautiful trees we call Douglas-fir.Hardcover print copies (black & white with a color cover) are available for a limited time at $45 each (including shipping) in the U.S., and$65 each (including shipping) internationally.
