This volume aims to present the essential work of geographer and historical ecologist William M. Denevan to explain the impact and influence his thinking had on the conceptual advancement not only in his own discipline, but in a range of related disciplines such as anthropology, archaeology, and environmental history. The book is organized around eight themes, demonstrating Denevan’s early and profound insights on topics that remain of current relevance today, and the scholarly impact his writing had on subsequent scholarship. The book is unique because it offers commentary from active scholars who address the impacts of Prof. Denevan's thinking and work on contemporary environmental and ecological issues, with a focus on several groundbreaking themes (e.g. historical demography, agricultural landforms, cultural plant geography, human environmental impacts, indigenous agro-ecology, tropical agriculture, livestock and landscape, and synthetic contributions). This book will be of interest to a range of scholars in geography, anthropology, archaeology, history, and ecology, as well as to environmental managers and practitioners, especially those working for non-profit organizations and government organizations tasked with finding ways to adapt to global environmental change.
Excerpt from Studies in the Field and Forest The descriptions of the phases of the year, included in this volume, were first printed in the years 1839 and 1840, in the "Boston Weekly Magazine," published by D. H. Ela and John B. Hall, The author afterwards, for several years, devoted himself entirely to the political press. Finding at last, that to keep along with his party, he must be prepared, on the arrival of every new era, to repudiate, if not to execrate the opinions and measures-which he had formerly defended, he renounced all connection with politics, and in 1853, resumed his occupation in that department of literature which he had so long neglected. The pieces now presented to the public are a selection from the contributions of the author to the periodical press, with the addition of several new ones. A large portion of these appeared originally in Charles M. Hovey's "Magazine of Horticulture," and a few others in the "Salem Gazette," in which the descriptions of the months were likewise reprinted.

Excerpt from book: CHAPTER V GREEN LEAVES AT WORK Between the budding and the falling leaf, Stretch happy skies, With colors and sweet cries, Of mating birds in uplands and in glades. The world is rife.?7. B. Aldrich. When spring, long waited for, has come indeed, and young leaves are unfolding in May sunshine, we find the ground beneath the branches strewed with half-transparent green or brownish scales. In city parks they litter the asphalt walks, and drift along their edges into little heaps. They are bud-scales, whose day of usefulness is over. They have braved all the rigors of storm and frost, while, folded safe within them, lay the foliage of the coming summer, destined to expand in tender colors under happy skies. But the bud-scales seldom have any beauty, save the beauty of fitness. They and the sleeping life which they enfoldtogether constitute the winter bud. It contains very little water in its tissues, and so can withstand low temperatures without freezing. The bud-scales live in a chill and sombre world, and when the sky is blue and full of light they fall and perish in the heart of spring. Yet, they are themselves imperfectly-formed and partially-developed leaves. Under certain exceptional circumstances they have shown their possibilities, and developed into typical leaves. And under most circumstances there is in them the arrested power to become like the green foliage of summer. Stunted, as they are, these scales have done work which perfect leaves could never do. Their horny substance has shed the cold rains of winter, resisted the frost, and protected the tips and shoots in which the life of the branches lay dormant. We owe to the bud-scales most of the beauty of the summer world. Their highest usefulness has been attained through sacrifice of thei...

Assessing Forest Ecosystem Health in the Inland West is a thorough reference for policymakers, resource managers, environmentalists, students, and anyone interested in using ecosystem management as a tool to address forest health problems in the Inland West. The book provides the reader with a survey of current conditions in the Inland West, their historical origins, assessments of available management tools, and analyses of the various choices available to policymakers. Its goal is to help people understand the Inland West forests so that public policies can reflect a constructive and realistic framework in which forests can be managed for sustained health. This resource is the product of a scientific workshop where 35 participants, including scientists, resource managers, administrators, and environmentalists, addressed the forest health problem in the Inland West. Synthesis chapters integrate the diverse knowledge and experience which participants brought to the workshop. They identify and link together many of the ecological, social, and administrative conditions which have created the forest health problem in the West. The book is unique in that it reflects a process that fostered the use of academic research, field realities, and industrial knowledge to define an interdisciplinary problem, establish rational policy objectives, and set-up “do-able” management approaches. The following topics are analyzed: Assessing forest ecosystem health in the Inland West Historical and anticipated changes in forest ecosystems in the Inland West Defining and measuring forest health Historical range of variability as a tool for evaluating ecosystem change Administrative barriers to implementing forest health problems Economic and social dimensions of the forest health problem Fire management Ecosystem and landscape management Assessing Forest Ecosystem Health in the Inland West will help facilitate sound resource planning because it brings together the problems facing the Inland West from an interdisciplinary perspective. This approach allows resource managers and policymakers creativity in planning and implementing strategies to confront forest health problems in the Inland West ecosystems.
