This acclaimed textbook is the most comprehensive available in the field of forest ecology. Designed for advanced students of forest science, ecology, and environmental studies, it is also an essential reference for forest ecologists, foresters, and land managers. The authors provide an inclusive survey of boreal, temperate, and tropical forests with an emphasis on ecological concepts across scales that range from global to landscape to microscopic. Situating forests in the context of larger landscapes, they reveal the complex patterns and processes observed in tree-dominated habitats. The updated and expanded second edition covers • Conservation• Ecosystem services • Climate change• Vegetation classification• Disturbance• Species interactions• Self-thinning• Genetics• Soil influences• Productivity• Biogeochemical cycling• Mineralization• Effects of herbivory• Ecosystem stability

While most efforts at biodiversity conservation have focused primarily on protected areas and reserves, the unprotected lands surrounding those area--the "matrix"--are equally important to preserving global biodiversity and maintaining forest health. In Conserving Forest Biodiversity, leading forest scientists David B. Lindenmayer and Jerry F. Franklin argue that the conservation of forest biodiversity requires a comprehensive and multiscaled approach that includes both reserve and nonreserve areas. They lay the foundations for such a strategy, bringing together the latest scientific information on landscape ecology, forestry, conservation biology, and related disciplines as they examine:the importance of the matrix in key areas of ecology such as metapopulation dynamics, habitat fragmentation, and landscape connectivitygeneral principles for matrix managementusing natural disturbance regimes to guide human disturbancelandscape-level and stand-level elements of matrix management the role of adaptive management and monitoringsocial dimensions and tensions in implementing matrix-based forest managementIn addition, they present five case studies that illustrate aspects and elements of applied matrix management in forests. The case studies cover a wide variety of conservation planning and management issues from North America, South America, and Australia, ranging from relatively intact forest ecosystems to an intensively managed plantation.Conserving Forest Biodiversity presents strategies for enhancing matrix management that can play a vital role in the development of more effective approaches to maintaining forest biodiversity. It examines the key issues and gives practical guidelines for sustained forest management, highlighting the critical role of the matrix for scientists, managers, decisionmakers, and other stakeholders involved in efforts to sustain biodiversity and ecosystem processes in forest landscapes.

Biodiversity is decreasing at the fastest rate in the history of the earth. The sustainable use of ecosystems allowing maintenance of biological diversity is an urgent problem that must be solved. The work featured in this book presents the results achieved by the RIHN project, together with reports on other international activities and related efforts, as ecologists, forestry scientists, environmental economists, and sociologists share in discussions of the issues.

Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development. Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained. Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity. Examples are presented on how biodiversity assessments can be made. Proposes how the critical gaps in our knowledge identified throughout the book could be filled through macroecological research and international co-operation.

The structure of most virgin forests in the western United States reflects a past disturbance history that includes forest fire. James K. Agee, an expert in the emergent field of fire ecology, analyzes the ecological role of fire in the creation and maintenance of natural western forests, focusing primarily on forest stand development patterns. His discussion of the natural fire environment and the environmental effects of fire is applicable to a wide range of temperate forests.

This country case study, part of the Operations Evaluation Department (OED) A Review of the 1991 World Bank Forest Strategy and Its Implementation, evaluates World Bank operations in Cameroon for their consistency with the strategy. The strategic aspects of those operations are judged here on their relevance, effectiveness, efficiency, institutional development, and sustainability. The fundamental objective of the forest policy reform in Cameroon was to establish a transparent, equitable, and sustainable management system for forest resources. The outcome of the reform process was limited, for four reasons. First, the government of Cameroon lacked genuine commitment and the capacity to carry out the reform. Second, key actors in the reform process (particularly foreign logging companies and the parliament) chose to oppose it. Third, partners such as the World Bank failed to devise an implementation strategy compatible with the underlying dynamics of political and socioeconomic changes in Cameroon. Finally, while Cameroon's forest policy is well codified in documents, it is poorly implemented. Although the reforms have led to increased tax revenues and increased the share of GDP attributable to the forest sector, the structural underpinnings of the sector have been little affected. Government agencies in the sector continue to be weak. The international logging companies that dominate the sector continue to have a free hand in the development and use of the forest resources of Cameroon. Local communities were left out of the reform process, despite the declared objective to include them in forest resource management. Overall, the interventions of the Bank inside and outside the forest sector in Cameroon were relevant to its strategic objectives, but they were neither efficacious nor efficient. Because of weak institutional development, the achievements are unlikely to be sustained. The Bank should focus its future reform efforts in Cameroon on the collection and dissemination of relevant and reliable information, working with a larger set of stakeholders, and using more Cameroonian expertise to gain local perspective and build capacity. The success of such an approach hinges on government commitment and the cooperation of other donor countries, including those with timber interests in Cameroon.

Tanzania is one of the most biologically diverse nations in the world. Traveling from west to east across Tanzania, one encounters an incredible array of ecosystems and species. Beginning at Lakes Victoria, Tanganyika, and Nyasa that form much of the western boundary of Tanzania, one finds the most diverse and some of the most spectacular concentrations of endemic fish in any of the world's lakes. Moving further inland from the lakes, one meets the woodlands and plains of Serengeti, Ngorongoro, Tarangire, and Lake Manyara. The assemblages and movements of large mammals in these protected areas are unparalleled worldwide. Traveling yet further to the east, one comes to Mount Kilimanjaro, the highest mountain in Africa. Mount Kilimanjaro is of sufficient height to not only contain seven major vegetation zones, but also maintain permanent glaciers. Finally, shortly before arriving at the Indian Ocean, one encounters the Eastern Arc Mountains, a series of isolated and geologically ancient mountains, which due to their height and proximity to the Indian Ocean intercept sufficient precipitation to support, in many areas, moist tropical forest. The Eastern Arc Mountains are among the richest sites biologically in all of Africa and harbor unusually high concentrations of endemic species - species whose geographic distribution are restricted to these mountains. Unfortunately, much of Tanzania's biodiversity is threatened by habitat alteration, destruction, and exploitation. The Eastern Arc forests face some of the most severe threats to any of Tanzania's biologically unique sites.
