دانلود کتاب Silviculture and Ecology of Western U.S. Forests

Silviculture, once regarded solely as reforestation and growing trees for timber, is understood today as also maintaining forest health, reducing fire potential, benefitting wildlife and aesthetics, and ensuring multiple options for the future against the uncertainties of a changing climate.Silviculture and Ecology of Western U.S. Forests, Second Edition, is a text for students, professional forest managers, and scientists that summarizes both early and contemporary research and principles relevant to the silviculture, ecology, and multi-purpose management of western U. S. forests. Based on its authors’ significant experiences and contributions in the field, as well as nearly 1000 additional references, Silviculture and Ecology remains the only text that focuses on silviculture in western U.S. forests—providing background and basis for current biological, ecological, and managerial practices. Detailed chapters on fire, tree growth, and management of complex stand structures, as well as shrub ecology and an ecosystem framework, are bolstered in the second edition. A new series of case studies illustrates how silvicultural practices are developed and modified as forests grow and new challenges and opportunities occur. Contemporary silvicultural practices, particularly pertaining to fire use, vegetation management, soil fertility, and fertilization have been updated, and modifications that enhance standard practices are demonstrated throughout the text. In this comprehensive reference, readers entering the field will come to understand the significance of carefully managing forests by conscious design, and experienced silviculturists will benefit from the edition’s up-to-date information, providing forest users with a greater range of ecosystem services and consumable products alike.
