USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.
