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 genus that may be able to deal with climate change. This book provides an overview of research activities and findings that highlights unique aspects of Douglas-fir physiology, genetics, and other related issues. The authors have pulled together a tremendous amount of information, starting with the evolutionary history and distribution of the genus Pseudotsuga.
