The text begins with an introduction to the basic elements of the science of ecology and the role of forests in the global ecosystem. The opening chapters describe how climate influences large-scale distribution of vegetation types, and how global warming might influence that distribution. After a look at factors that influence landscape patterns, the focus shifts to topics that include temporal dynamics, biological diversity, and soils. Subsequent chapters deal with primary productivity, nutrient cycling, herbivory, ecosystem stability, and factors contributing to ecosystem collapse such as acid rain and mismanagement. A concluding chapter discusses principles of sustainable forest management.
