A Comprehensive Multiscaled Approach
Author: David B. Lindenmayer,Jerry F. Franklin
Publisher: Island Press
View: 849While 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.
A Study of the Eastern Arc Mountains
Author: W.D. Newmark
Publisher: Springer Science & Business Media
View: 1598Tanzania 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.

View: 1105Forests play important role in combating desertification, preventing erosion problems, other protective functions, climatic change and acting as carbon reservoirs and sinks. Forests, the biodiversity they contain and the ecological function they maintain, are a heritage of mankind. The vital role of forests in protecting fragile ecosystems, watersheds and freshwater reservoirs and as storehouses of rich biodiversity should be recognized. Forests contain not only woody species and wild animals but also a wealth of other species of actual or potentially socio-economic importance at the global, national and local levels, including wild relatives of important crop species. Biodiversity is the variety and variability of plant, animal and micro organism in a ecosystem. Biodiversity, in wild and domesticated forms, is the source for most of humanity food, medicine, clothing and housing, most of the cultural diversity and most of the intellectual and spiritual inspirations. In other words, it is the very basis of man s being. Currently, there is severe and widespread loss of biodiversity because of a variety of factors and therefore its conservation is of utmost importance. Conservation and development are partners in the process of environmental protection. To maintain and increase the ecological, biological, climatic, socio-cultural and economic contributions of forests, their conservation and management are urgently required. Biological diversity (biodiversity) is also to be preserved to achieve sustainable development. The book is a sincere effort of the authors to provide compiled information on the subject matter of forest environment and diversity. It includes the impact of forests on environment, basic concept, status and extent of biodiversity, its loss and suggests ways and means of conservation for achieving sustainable development.

Forest Sector Development in a Difficult Political Economy

View: 3667This 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.

Managing for Complex Forest Stand Structures
Author: Kevin O'Hara
Publisher: OUP Oxford
View: 9597This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.
Valuation in Tropical Forest Ecosystems
Author: K. N. Ninan
Category: Business & Economics
View: 9202Economic valuation of biodiversity and ecosystem services is possibly the most powerful tool for halting the loss of biodiversity while maintaining incomes and livelihoods. Yet rarely have such approaches been applied to tropical forest ?hotspots?, which house the vast majority of the planets plant and animal species. This ground-breaking work is the most comprehensive and detailed examination of the economics of environmental valuation and biodiversity conservation to date. Focusing on the Western Ghats of India, one of the top biodiversity hotspots in the world, this volume looks at a cross-section of local communities living within or near sanctuaries and reserve forests such as coffee growers, indigenous people and farmers-cum-pastoralists to assess the use and non-use values that people derive from tropical forests. It also looks at the extent of their dependence on forests for various goods and services, and examines their perceptions and attitudes towards biodiversity conservation and wildlife protection. The book concludes with an assessment of the institutional alternatives and policies for promoting biodiversity conservation through economic valuation methods.Related titlesEconomics for Collaborative Environmental Management (2005) 1-84407-095-6
