Economic loss due to tree damage by black bears (Ursus americanus) on managed timberlands has been valued at several million dollars annually in the Pacific Northwest. While bear damage to trees may negatively affect timber production, it also alters forest structure and habitat that may contribute to forest wildlife diversity. I studied the relationship between bear damage to coast Douglas-fir (Pseudotsuga menziesii var. menziesii) trees and response of cavity nesting birds on the Hoopa Valley Indian Reservation. I measured disservices from bear damage by calculating current and future timber revenue loss, and ecosystem services by calculating forest structural complexity, abundance and diversity of cavity nesting birds, and woodpecker activity. Bear damage negatively affected tree growth and estimated lumber recovery. Forest structural complexity was positively correlated with bear damage, and cavity nester abundance and woodpecker foraging activity were positively correlated to forest structural complexity and bear damage. Pileated woodpeckers and red-breasted sapsuckers used bear damaged trees out of proportion to their availability, and pileated woodpeckers selected for more structurally complex sample units. Information from this study advances our understanding of the potential for bear foraging to negatively affect economic revenue and the trade-offs which help to create habitat conditions favoring other important wildlife species. To the best of our knowledge, this is the first study to evaluate ecosystem services for multiple species in relation to disservices from another species. Understanding the costs and benefits of bear damage can help guide management decisions vital to forest managers both on and off tribal lands.

For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds’ beauty and extraordinary diversity, but also their importance to ecosystems worldwide. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms. In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services—the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation. Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions—all seen through the lens of human well-being—to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.

As humanity presses down inexorably on the natural world, people debate the extent to which we can save the Earth's millions of different species without sacrificing human economic welfare. But is this argument wise? Must the human and natural worlds be adversaries? In this book, ecologist Michael Rosenzweig finds that ecological science actually rejects such polarization. Instead it suggests that, to be successful, conservation must discover how we can blend a rich natural world into the world of economic activity. This revolutionary, common ground between development and conservation is called reconciliation ecology: creating and maintaining species-friendly habitats in the very places where people live, work, or play. The book offers many inspiring examples of the good results already achieved. The Nature Conservancy, for instance, has a cooperative agreement with the Department of Defense, with more than 200 conservation projects taking place on more than 170 bases in 41 states. In places such as Elgin Air Force Base, the human uses-testing munitions, profitable timbering and recreation--continue, but populations of several threatened species on the base, such as the long-leaf pine and the red-cockaded woodpecker, have been greatly improved. The Safe Harbor strategy of the Fish & Wildlife Service encourages private landowners to improve their property for endangered species, thus overcoming the unintended negative aspects of the Endangered Species Act. And Golden Gate Park, which began as a system of sand dunes, has become, through human effort, a world of ponds and shrubs, waterfowl and trees. Rosenzweig shows that reconciliation ecology is the missing tool of conservation, the practical, scientifically based approach that, when added to the rest, will solve the problem of preserving Earth's species.

That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.

For nearly 60 years, Timber: Structure, Properties, Conversion, and Use has been the authoritative text on timber technology. Now in its seventh edition, this book remains a vital resource, providing accurate, comprehensive, and fact-driven information for students and professionals in the field. From basic coverage of timber structure, properties, processing, and utilization, to more in-depth scientific investigations, this book covers all the issues and topics of concern to readers with a wide range of levels of sophistication. Timber technology has not stood still since the last revision; Timber: Structure, Properties, Conversion, and Use has kept the pace, exploring such high-tech topics as computer-aided wood identification and log conversion, radio frequency drying of wood, enhancement of wood with plastics, application of preservatives with high-pressure vacuum systems, and the development and application of flame-retardant solutions. Other timely updates include enlarging the chapter on mechanical performance to cover elastic behavior, toughness, and the use of structural-sized timber for strength tests. The chapter on board materials has also been extensively updated and enlarged to include information on new boards and structural composites that have emerged since the last edition. One of the most important strengths of Timber: Structure, Properties, Conversion, and Use is its versatility as a reference for timber professionals while remaining approachable to students in the field. Evidence of the book?s comprehensiveness and versatility becomes clear as it teaches readers about such wide-ranging topics as: identification and nomenclature of timbers variability in cellular features between species principal chemical constituents in timber structural variability caused by natural defects such as bark pockets, resin streaks, and brittleheart determination of density and moisture content in timber thermal and acoustic properties of wood conversion equipment such as circular saws, band saws, frame saws, and chipper canters health and safety issues in the industry adhesives, metal connectors, and joint design forest and millyard pests application of preservatives and finishes From basic identification and timber nomenclature to methods of sap displacement and tests of electrical conductivity, Timber: Structure, Properties, Conversion, and Use covers it all. And while it is no longer possible for any one individual to write authoritatively on every aspect of timber technology, embracing as it does structure, properties, conversion, utilization, and behavior in service, J. M. Dinwoodie has gathered expert opinions and expanded on original author H. E. Desch?s approach and vision to continue to provide the authoritative text on timber technology.
