Book Description
"This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Book Description
In stands with significant mountain pine beetle (MPB) mortality, forest managers face a range of choices including clearcut harvesting, partial cutting, various rehabilitation strategies, and non-intervention. These choices involve many long-term costs, benefits, and risks, some of which can be assessed through economic analysis. After reviewing the context for this issue, the authors provided case studies that span the more likely stand-level problems faced by decision makers. All analyses were conducted from the perspective of the landowner (i.e., government) rather than the user of the resource (i.e., licensee). The insights from the case studies form a basis to answer the following core questions: Are some stand types better left unsalvaged? What economic/silvicultural assumptions produce higher stand values when salvaging is foregone? In areas that cannot be salvaged, is reforestation a profitable investment? Finally, does partial cutting make sense economically?--Document.

Book Description
We developed a decision-support framework that integrates scenario analysis and multi-criteria decision analysis and used it to analyze forest renewal in the study area of the Quesnel Timber Supply Area. Two consensus-based scenarios were constructed to represent the target future conditions: strong forest sector and forest resilience/economic diversification. Renewal strategies were constructed using multi-criteria decision analysis and sets of criteria specific to each scenario. Impacts of the renewal strategies are measured in terms of several timber and non-timber indicators. The key economic and timber-related impacts are linked to merchantable volume. Ecological impacts are assessed by analyzing wildlife communities associated with the broad habitat categories. None of the strategies generated for the scenarios was acceptable in terms of all criteria and outcomes. Further revisions of the scenarios and criteria, with the involvement of local stakeholders, is therefore recommended for decision-making. The integrated framework developed for this study is general and allows for other community and forest management concerns to be incorporated. The framework demonstrates how the stakeholders' goals regarding their community's future are formulated and how the conflicts between multiple criteria may be addressed.

Book Description
Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.

Book Description
Bark Beetles: Biology and Ecology of Native and Invasive Species provides a thorough discussion of these economically important pests of coniferous and broadleaf trees and their importance in agriculture. It is the first book in the market solely dedicated to this important group of insects, and contains 15 chapters on natural history and ecology, morphology, taxonomy and phylogenetics, evolution and diversity, population dynamics, resistance, symbiotic associations, natural enemies, climate change, management strategies, economics, and politics, with some chapters exclusively devoted to some of the most economically important bark beetle genera, including Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus. This text is ideal for entomology and forestry courses, and is aimed at scientists, faculty members, forest managers, practitioners of biological control of insect pests, mycologists interested in bark beetle-fungal associations, and students in the disciplines of entomology, ecology, and forestry. - Provides the only synthesis of the literature on bark beetles - Features chapters exclusively devoted to some of the most economically important bark beetle genera, such as Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus - Includes copious color illustrations and photographs that further enhance the content

Book Description
Habitat loss and degradation that comes as a result of human activity is the single biggest threat to biodiversity in the world today. Habitat Fragmentation and Landscape Change is a groundbreaking work that brings together a wealth of information from a wide range of sources to define the ecological problems caused by landscape change and to highlight the relationships among landscape change, habitat fragmentation, and biodiversity conservation. The book: synthesizes a large body of information from the scientific literature considers key theoretical principles for examining and predicting effects examines the range of effects that can arise explores ways of mitigating impacts reviews approaches to studying the problem discusses knowledge gaps and future areas for research and management Habitat Fragmentation and Landscape Change offers a unique mix of theoretical and practical information, outlining general principles and approaches and illustrating those principles with case studies from around the world. It represents a definitive overview and synthesis on the full range of topics that fall under the widely used but often vaguely defined term "habitat fragmentation."
