DOWNLOAD EBOOKOver the past decade, a sea change has occurred in the field of forestry. A vastly increased understanding of how ecological systems function has transformed the science from one focused on simplifying systems, producing wood, and managing at the stand-level to one concerned with understanding and managing complexity, providing a wide range of ecological goods and services, and managing across broad landscapes.Creating a Forestry for the 21st Century is an authoritative and multidisciplinary examination of the current state of forestry and its relation to the emergent field of ecosystem management. Drawing upon the expertise of top professionals in the field, it provides an up-to-date synthesis of principles of ecosystem management and their implications for forest policy. Leading scientists, including Malcolm Hunter, Jr., Bruce G. Marcot, James K. Agee, Thomas R. Crow, Robert J. Naiman, John C. Gordon, R.W. Behan, Steven L. Yaffee, and many others examine topics that are central to the future of forestry: new understandings of ecological processes and principles, from stand structure and function to disturbance processes and the movement of organisms across landscapes challenges to long-held assumptions: the rationale for clearcutting, the wisdom of short rotations, the exclusion of fire traditional tools in light of expanded goals for forest landscapes managing at larger spatial scales, including practical information and ideas for managing large landscapes over long time periods the economic, organizational, and political issues that are critical to implementing successful ecosystem management and developing institutions to transform knowledge into action Featuring a 16-page center section with color photographs that illustrate some of the best on-the-ground examples of ecosystem management from around the world, Creating a Forestry for the 21st Century is the definitive text on managing ecosystems. It provides a compelling case for thinking creatively beyond the bounds of traditional forest resource management, and will be essential reading for students; scientists working in state, federal, and private research institutions; public and private forest managers; staff members of environmental/conservation organizations; and policymakers.

DOWNLOAD EBOOKIn the mid 1970s two events led me to get to know the Yorkshire Dales better than I had previously. Since 1964 I had been to the Malham Tarn Field Centre with groups of students, first from the University of Edinburgh and then from the University of York, and my family very much enjoyed the summer days we spent amid this magnificent hill scenery. In 1976, the British Ecological Society and the National Trust jointly worked on a survey of the biological interest of the National Trust properties of the Kent, East Anglian and Yorkshire Regions. Malham Tarn itself, and the surrounding farms, formed one of the twenty properties of the Yorkshire Region. I spent the bank holiday, that commemorated the Queen's Silver Jubilee, at Malham, looking fairly closely at the National Trust's landholding there. Miss Sarah Priest, who also looked at the National Trust properties, and I produced a report in late 1977, attempting both to describe and to evaluate the nature resources of the National Trust in Yorkshire. In the following year, 1978, the Nature Conservancy Council wanted to survey the whole of the upland area that was known as the Malhaml Arncliffe SSSI (Site of Special Scientific Interest). A contract to look at such an exciting area, considering where boundaries should go, and looking to see if there were important areas of habitat that should be brought within the SSSI, was a superb practical antidote to an office in the University.
