Big-Leaf Mahogany is the most important commercial timber species of the tropics. Current debate concerning whether to protect it as an endangered species has been hampered by the lack of complete, definitive scientific documentation. This book reports on vital research on the ecology of big-leaf mahogany, including genetic variations, regeneration, natural distribution patterns and the silvicutural and trade implications for the tree.

Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

The World Bank's Forests Strategy, adopted in October 2002, charts a path for the Bank's proactive engagement in the sector to help attain the goal of poverty reduction without jeopardizing the environmental values intrinsic to sustainability. This strategy replaces the Bank's 1991 Forestry Strategy, and was developed on the basis of the findings of an independent review of the 1991 strategy and a two-year consultative process with development partners and stakeholders around the world. The revised strategy, Sustaining Forests, is built on three guiding pillars: harnessing the potential of forests to reduce poverty, integrating forests into sustainable economic development, and protecting global forest values. Recognizing the key role forests play in contributing to the livelihoods of people living in extreme poverty, government and local ownership of forest policies and interventions are emphasized along with the development of appropriate institutions to ensure good governance and the mainstreaming of forests into national development planning. The strategy also aims to support ecologically, socially and economically sound management of production forests by ensuring good management practices through application of safeguard procedures and independent monitoring and certification. Implementation of the strategy will center on building and strengthening partnerships with the private sector, non-governmental organizations, and other donor agencies to promote better forest conservation and management at country and global levels.
