Fundamental changes have occurred in all aspects of forestry over the last 50 years, including the underlying science, societal expectations of forests and their management, and the evolution of a globalized economy. This textbook is an effort to comprehensively integrate this new knowledge of forest ecosystems and human concerns and needs into a management philosophy that is applicable to the vast majority of global forest lands. Ecological forest management (EFM) is focused on policies and practices that maintain the integrity of forest ecosystems while achieving environmental, economic, and cultural goals of human societies. EFM uses natural ecological models as its basis contrasting it with modern production forestry, which is based on agronomic models and constrained by required return-on-investment. Sections of the book consider: 1) Basic concepts related to forest ecosystems and silviculture based on natural models; 2) Social and political foundations of forestry, including law, economics, and social acceptability; 3) Important current topics including wildfire, biological diversity, and climate change; and 4) Forest planning in an uncertain world from small privately-owned lands to large public ownerships. The book concludes with an overview of how EFM can contribute to resolving major 21st century issues in forestry, including sustaining forest dependent societies.

Most people think of New Jersey as a suburban-industrial corridor that runs between New York and Philadelphia. Yet in the low center of the state is a near wilderness, larger than most national parks, which has been known since the seventeenth century as the Pine Barrens. The term refers to the predominant trees in the vast forests that cover the area and to the quality of the soils below, which are too sandy and acid to be good for farming. On all sides, however, developments of one kind or another have gradually moved in, so that now the central and integral forest is reduced to about a thousand square miles. Although New Jersey has the heaviest population density of any state, huge segments of the Pine Barrens remain uninhabited. The few people who dwell in the region, the "Pineys," are little known and often misunderstood. Here McPhee uses his uncanny skills as a journalist to explore the history of the region and describe the people—and their distinctive folklore—who call it home.
