The Practice of Silviculture

The most up-to-date, comprehensive resource on silviculture that covers the range of topics and issues facing today's foresters and resource professionals

The tenth edition of the classic work, The Practice of Silviculture: Applied Forest Ecology, includes the most current information and the results of research on the many issues that are relevant to forests and forestry. The text covers such timely topics as biofuels and intensive timber production, ecosystem and landscape scale management of public lands, ecosystem services, surface drinking water supplies, urban and community greenspace, forest carbon, fire and climate, and much more.

In recent years, silvicultural systems have become more sophisticated and complex in application, particularly with a focus on multi-aged silviculture. There have been paradigm shifts toward managing for more complex structures and age-classes for integrated and complementary values including wildlife, water and open space recreation. Extensively revised and updated, this new edition covers a wide range of topics and challenges relevant to the forester or resource professional today. This full-color text offers the most expansive book on silviculture and:

• Includes a revised and expanded text with clear language and explanations

• Covers the many cutting-edge resource issues that are relevant to forests and forestry

• Contains boxes within each chapter to provide greater detail on particular silvicultural treatments and examples of their use

• Features a completely updated bibliography plus new photographs, tables and figures

The Practice of Silviculture: Applied Forest Ecology, Tenth Edition is an invaluable resource for students and professionals in forestry and natural resource management.
