Lianas are woody vines that were the focus of intense study by early ecologists, such as Darwin, who devoted an entire book to the natural history of climbing plants. Over the past quarter century, there has been a resurgence in the study of lianas, and liana are again recognized as important components of many forests, particularly in the tropics. The increasing amount of research on lianas has resulted in a fundamentally deeper understanding of liana ecology, evolution, and life-history, as well as the myriad roles lianas play in forest dynamics and functioning. This book provides insight into the ecology and evolution of lianas, their anatomy, physiology, and natural history, their global abundance and distribution, and their wide-ranging effects on the myriad organisms that inhabit tropical and temperate forests.

Starting in 1994, Cameroon introduced regulatory and market-based reforms to regulate access to its rainforests, balance public and private interests in those forests, and integrate wider economic, cultural, and environmental perspectives of the value of forests. Based on historical data and extensive interviews, this report concludes that the reforms brought order over the most aggressively competing interests and started to address deeper social and environmental issues, but a significant unfinished agenda remains. On the positive side, information on the boundaries, ownership, use rights, and management of Cameroon s rainforests has become available for public scrutiny, along with information on detection and prosecution of illegal activities. Better and better known rules of the game have improved forest governance and collaboration between forest institutions and civil society. More than 60 percent of Cameroon s rainforests are under management systems that emphasize sustainability. Illegal logging has declined sharply managed parks and production forests, although it persists in rural areas. The restructured forest industry has adopted internationally recognized management practices that have started to align logging with the forest s capacity to regenerate. Cameroon has established rules to preserve customary rights to forests, and community forests have progressed despite unanticipated challenges. Yet further reform is needed. Deeper recognition of the customary rights of all people who depend on Cameroon s forests, regardless of ethnicity, is vital. Timber and nontimber forest products like medicinal plants and bush meat remain subject to illegal exploitation outside state forests. Cameroon needs qualified eco-investors to sustain conservation and diminish reliance on timber production. Community involvement in the management of all types of forests should expand further. Great attention to local markets and small firms will strengthen forest governance and the forest industry in important ways. Rewarding responsible corporate behavior with more lenient bank guarantees and tax incentives may prove as important for conserving forests as punishing corporate misbehavior.

Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Almost half of all life on earth may exist in the world's forest canopies. They may also play a vital role in maintaining the planet's climate, yet they remain largely unexplored owing to difficulties of access. They are renowned for their great diversity and role in forest functioning, yet there are still great gaps in the understanding of this `last biological frontier'. This seminal book shows how canopy science is now in a position to answer many of the outstanding questions, among which are some of the most pressing environmental issues society is presently facing. It represents a major summary of the current understanding of canopy ecology, and maps a path forward into a greater understanding of tropical forest ecology and management at a time when the very future of this ecosystem is threatened by humanity's actions.

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.

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
