Book Description
Excerpt from Analyses of Great Smoky Mountain Red Spruce Tree Ring Data Drs. Ord and Derr performed a spatial analysis on the data. They concluded that there was a tendency for ring widths to diminish in recent years and that there is a strong spatial dependence ill forecast residuals that cannot be explained by geographic or biotic factors alone. They did not consider climate, which they mention could explain some of the remaining spatial dependence. The analysis performed here is novel for the field of dendrochronology and may lead to useful results in the future.

Book Description
In the early 1980s there were several published reports of recent, unexplained increases in mortality of red spruce in the Adirondack Mountains and the northern Appalachian Mountains of the eastern United States. These reports coincided with documentation of reductions in radial growth of several species of pine in the southeastern United States, and with the severe, rapid, and widespread decline of Norway spruce, silver fir, and some hardwoods in central Europe. In all of these instances, atmospheric deposition was hypothesized as the cause of the decline. (Throughout this volume, we use the term "decline" to refer to a loosely synchronized regional-scale deterioration of tree health which is brought about by a combination of stress factors. These may be biotic or abiotic in nature, and the combinations may differ from site to site. ) Heated public debate about the causes and possible cures for these forest declines ensued. Through the course of this debate, it became clear that information about forest health and air pollution effects on forests was inadequate to meet policymakers' needs. Ecology and Decline of Red Spruce in the Eastern United States addresses that gap for eastern spruce fir forests and represents the culmination of a great deal of research conducted in recent years. The focus is on red spruce because the decline of red spruce was both dramatic and inexplicable and because of the great amount of information gathered on red spruce.

Book Description
Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

Book Description
A collection of captivatingly meditative essays that display a deep understanding of Buddhist belief, wildness, wildlife, and the world from an American cultural force. With thoughts ranging from political and spiritual matters to those regarding the environment and the art of becoming native to this continent, the nine essays in The Practice of the Wild display the deep understanding and wide erudition of Gary Snyder. These essays, first published in 1990, stand as the mature centerpiece of Snyder's work and thought, and this profound collection is widely accepted as one of the central texts on wilderness and the interaction of nature and culture.
