From the East Coast to the Mississippi River, from southern Canada to northern Florida, the eastern deciduous forest of North America is home to a wonderfully diverse range of wildlife and ecosystems. Richard H. Yahner integrates basic biological principles into an account of the ecological consequences of society's actions. As Yahner traces the history of conservation of the forest, he discusses relevant issues such as the loss of biodiversity, acid deposition, ozone depletion, and global climatic change. This new edition includes the most up-to-date information on the forest and its wildlife, with special attention given to contemporary conservation issues. The result is a timely and useful tool for anyone who wants to know or hopes to help one of North America's great natural resources.

In recent years, conflicts between ecological conservation and economic growth forced a reassessment of the motivations and goals of wildlife and forestry management. Focus shifted from game and commodity management to biodiversity conservation and ecological forestry. Previously separate fields such as forestry, biology, botany, and zoology merged into a common framework known as conservation biology and resource professionals began to approach natural resource problems in an interdisciplinary light. Wildlife Habitat Management: Concepts and Applications in Forestry presents an integrated reference combining silvicultural and forest planning principles with principles of habitat ecology and conservation biology. With extensive references and case studies drawn from real situations, this book begins with general concepts such as habitat selection, forest composition, influences on habitat patterns, and the dynamics of disturbance ecology. It considers management approaches for specific habitats including even-aged and uneven-aged systems, riparian areas, and dead wood and highlights those approaches that will conserve and manage biodiversity. The author discusses assessment and prioritization policies, monitoring techniques, and ethical and legal issues that can have worldwide impact. Detailed appendices provide a glossary, scientific names, and tools for measuring and interpreting habitat elements. Writing in a species-specific manner, the author emphasizes the need to consider the potential effects of management decisions on biodiversity conservation and maintains a holistic approach throughout the book. Drawing from the author’s more than 30 years working and teaching in natural resources conservation, Wildlife Habitat Management: Concepts and Applications in Forestry provides a synopsis of current preservation techniques and establishes a common body of knowledge from which to approach the conservation of biodiversity in the future.

Geographic Information Systems (GIS) provide a powerful tool for the investigation of species-habitat relationships and the development of wildlife management and conservation programs. However, the relative ease of data manipulation and analysis using GIS, associated landscape metrics packages, and sophisticated statistical tests may sometimes cause investigators to overlook important species-habitat functional relationships. Additionally, underlying assumptions of the study design or technology may have unrecognized consequences. This volume examines how initial researcher choices of image resolution, scale(s) of analysis, response and explanatory variables, and location and area of samples can influence analysis results, interpretation, predictive capability, and study-derived management prescriptions. Overall, most studies in this realm employ relatively low resolution imagery that allows neither identification nor accurate classification of habitat components. Additionally, the landscape metrics typically employed do not adequately quantify component spatial arrangement associated with species occupation. To address this latter issue, the authors introduce two novel landscape metrics that measure the functional size and location in the landscape of taxon-specific ‘solid’ and ‘edge’ habitat types. Keller and Smith conclude that investigators conducting GIS-based analyses of species-habitat relationships should more carefully 1) match the resolution of remotely sensed imagery to the scale of habitat functional relationships of the focal taxon, 2) identify attributes (explanatory variables) of habitat architecture, size, configuration, quality, and context that reflect the way the focal taxon uses the subset of the landscape it occupies, and 3) match the location and scale of habitat samples, whether GIS- or ground-based, to corresponding species’ detection locations and scales of habitat use.

Reviews & synthesizes info. about the structure, function, & components of steppe & desert grassland ecosystems in the western U.S. with special emphasis on the ecological roles & requirements of wildlife species. It is designed to draw attention to some wildlife topics that have been particularly neglected for western grasslands, & represents a cross section of the papers orally presented at the symposium as well as some additional papers solicited afterwards. Those interested in sustaining the ecological health, productivity, & biological diversity of western grassland ecosystems will find this publication valuable.
