Tree-ring dating, or dendrochronology, is the study of the chronological sequence of annual growth rings in trees. This book--a seminal study in its field--provides a simple yet eloquent introduction to the discipline, explaining what a dendrochronologist does both in the field and in the laboratory. Authors Stokes and Smiley first explain the basic principles of tree-ring dating, then describe details of the process, step by step, from the time a sample is collected until it is incorporated into a master chronology. The book focuses on coniferous evergreens of the Southwest, particularly pi–ons, because they have wide geographic distribution, constitute a large population, and show excellent growth response to certain controlling factors. The book is specifically concerned with the task of establishing a calendar date for a wood or charcoal specimen. This concise but thorough explication of an important discipline will make dendrochonology more meaningful to students and professionals in archaeology, forestry, hydrology, and global change.

This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines.

The analysis of tree-ring patterns, or dendrochronology, is a very exact science and an important dating technique. The basis of the method is misleadingly simple: that overlap of successive older ring patterns can generate a master chronology and samples of unknown age can then be checked against this. This book, published originally in 1982, traces the development of a specific project from its inception to the successful completion of some of the longest chronologies in Europe. In doing so it looks at some of the problems associated with the subject and at the levels of precision possible. After outlining the techniques associated with the measurement and processing of tree-ring patterns, the author traces an attempt to construct such an independent chronology in a new area. The book breaks naturally into sections conditioned by the availability of timbers and these can be listed as modern, late medieval, medieval, early medieval and prehistoric. As far as possible the results are presented in the order in which things happened, thus preserving the sense of a developing subject.

This book is a review and description of the state-of-the-art methods of tree-ring analy~is with specific emphasis on applications in the environmental sciences. Traditionally, methods of tree-ring analysis, or more properly in this case methods 0/ dendrochronology, were developed and used for dating archaeological and historical structures and for reconstructing past climates. The classic book Tree Rings and Climate, by H.C. Fritts, published in 1976, provided a superb introduction to the science and an in-depth description of techniques useful for extracting climatic information from tree rings. This book, which was published by Academic Press, is sadly out of print and, even though only 12 years old, lim ited in its methods and applications. This is owing to the extremely rapid development of the science since the 1970s. Only recently have tree rings as environmental sensors been fully recog nized as a valuable tool in detecting environmental change. For example, tree ring measurements have been critically important in studies of forest decline in Europe and North America. There are also attempts to use tree-ring analysis for ecological prognosis to solve large-scale regional problems including the sustain ability of water supplies, prediction of agricultural crops, and adoption of silvi cultural measures in response to ecological changes. More speculatively, dendro chronological methods are also used for dating and evaluating some astrophysical phenomena and for indicating possible increase in the biospheric carrying capac ity due to increased atmospheric carbon dioxide.

At a meeting of dendrochronologists an American colleague described the effects of volcanic eruptions on annual ring formation in bristlecone pines. I knew very little about either volcanoes or American pines! At the same meeting European scientists spoke on the dendrochronological dating of lakeshore settlements and the effects of larch bud moth attack on trees in the Alps. It is possible that American participants were not in a position to fully appreciate these papers either. In other words, dendrochronology is an extremely interdisciplinary science; its facets range from modern statistics on wood anatomy to the history of art. It is difficult even for dendrochronol ogists to keep in touch with the whole spectrum, and even more difficult for the layman to obtain an overall view of the many methods and fields of application. In recent times specialisation has begun to hinder communication be tween the various sectors. Archaeologists, for instance, set up their own dendrochronological laboratories and construct independent chronologies to serve their particular interests. The scientific institutions which previously carried out such work are now turning more and more to strongly statistically or biologically-oriented questions. The full wealth of information contained in tree rings, however, will be revealed only when dendrochronologists make a concerted effort to relate the findings of the different fields. In spite of inevitable specialisation, it is necessary that the expert concern himself with the work of his colleagues.
