Although bats are often thought of as cave dwellers, many species depend on forests for all or part of the year. Of the 45 species of bats in North America, more than half depend on forests, using the bark of trees, tree cavities, or canopy foliage as roosting sites. Over the past two decades it has become increasingly clear that bat conservation and management are strongly linked to the health of forests within their range. Initially driven by concern for endangered species—the Indiana bat, for example—forest ecologists, timber managers, government agencies, and conservation organizations have been altering management plans and silvicultural practices to better accommodate bat species. Bats in Forests presents the work of a variety of experts who address many aspects of the ecology and conservation of bats. The chapter authors describe bat behavior, including the selection of roosts, foraging patterns, and seasonal migration as they relate to forests. They also discuss forest management and its influence on bat habitat. Both public lands and privately owned forests are considered, as well as techniques for monitoring bat populations and activity. The important role bats play in the ecology of forests—from control of insects to nutrient recycling—is revealed by a number of authors. Bat ecologists, bat conservationists, forest ecologists, and forest managers will find in this book an indispensable synthesis of the topics that concern them.

The Global Forest Products Model (GFPM) book provides a complete introduction to this widely applied computer model. The GFPM is a dynamic economic equilibrium model that is used to predict production, consumption, trade, and prices of 14 major forest products in 180 interacting countries. The book thoroughly documents the methods, data, and computer software of the model, and demonstrates the model's usefulness in addressing international economic and environmental issues. The Global Forest Products Model is written by an international multi-disciplinary team and is ideal for graduate students and professionals in forestry, natural resource economics, and related fields. It explains trends in world forest industries in the simplest terms by explaining the economic theory underlying the model. It describes six applications of the GFPM, three of which were commissioned by the Food Agriculture of the United Nations, the USDA Forest Service, and New Zealand Research. The authors show how to apply the model to real issues such as the effects of the Asian economic crisis on the forest sector, the effects of eliminating tariffs on international trade and production, and the international effects of national environmental policies. They provide complete explanations on how to use the GFPM software, prepare the data, make the forecasts, and summarize the results with tables and graphs. Comprehensive, and rigorous description of the world forestry sector Written by an international multi-disciplinary team Thorough description of data and methods In-depth applications to modern economic and policy issues Detailed documentation of the computer software Suitable for students, researchers, and decision makers
