President John F. Kennedy officially dedicated the Pinchot Institute for Conservation Studies on September 24, 1963 to further the legacy and activism of conservationist Gifford Pinchot (1865-1946). Pinchot was the first chief of the United States Forest Service, appointed by Theodore Roosevelt in 1905. During his five-year term, he more than tripled the national forest reserves to 172 million acres. A pioneer in his field, Pinchot is widely regarded as one of the architects of American conservation and an adamant steward of natural resources for future generations. Author Char Miller highlights many of the important contributions of the Pinchot Institute through its first fifty years of operation. As a union of the United States Forest Service and the Conservation Foundation, a private New York-based think tank, the institute was created to formulate policy and develop conservation education programs. Miller chronicles the institution's founding, a donation of the Pinchot family, at its Grey Towers estate in Milford, Pennsylvania. He views the contributions of Pinchot family members, from the institute's initial conception by Pinchot's son, Gifford Bryce Pinchot, through the family's ongoing participation in current conservation programming. Miller describes the institute's unique fusion of policy makers, scientists, politicians, and activists to increase our understanding of and responses to urban and rural forestry, water quality, soil erosion, air pollution, endangered species, land management and planning, and hydraulic franking. Miller explores such innovative programs as Common Waters, which works to protect the local Delaware River Basin as a drinking water source for millions; EcoMadera, which trains the residents of Cristobal Col—n in Ecuador in conservation land management and sustainable wood processing; and the Forest Health-Human Health Initiative, which offers health-care credits to rural American landowners who maintain their carbon-capturing forestlands. Many of these individuals are age sixty-five or older and face daunting medical expenses that may force them to sell their land for timber. Through these and countless other collaborative endeavors, the Pinchot Institute has continued to advance its namesake's ambition to protect ecosystems for future generations and provide vital environmental services in an age of a burgeoning population and a disruptive climate.

Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. 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. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.
