Old Growth in a New World: A Pacific Northwest Icon Reexamined
Format: PDF / Kindle (mobi) / ePub
Old Growth in a New World untangles the complexities of the old growth concept and the parallel complexity of old-growth policy and management. It brings together more than two dozen contributors—ecologists, economists, sociologists, managers, historians, silviculturists, environmentalists, timber producers, and philosophers—to offer a broad suite of perspectives on changes that have occurred in the valuing and management of old-growth forests in the Pacific Northwest over the past thirty years. The book
• introduces the issues and history of old-growth values and conservation in the Pacific Northwest;
• explores old growth through the ideas of leading ecologists and social scientists;
• addresses the implications for the future management of old-growth forests and considers how evolving science and social knowledge might be used to increase conservation effectiveness.
By confronting the complexity of the old-growth concept and associated policy and management challenges, Old Growth in a New World encourages productive discussion on the future of old growth in the Pacific Northwest and offers options for more effective approaches to conserving forest biodiversity.
diminished, and it can have more characteristics of the dense, or another, structure. Growth and mortality can also cause a savanna structure to change to an old-growth structure. FIGURE 24.1. Each forest stand changes in structure along many possible pathways with growth, senescence, and disturbances. Black lines show changes created by growth, and gray lines show pathways created by disturbances. Each structure supports some species and other values. Other classifications exist in addition
disappear from an area before old growth regrows. Managing Old Growth as Part of a “Triad” A robust way to provide all structures and their values is the triad system (fig. 24.2; Seymour and Hunter, 1999). The Pacific Northwest and many other forest areas of the world have been gradually developing toward this triad. The triad assumes each forested ecosystem can be divided into three zones, and the amount, placement, and treatment of each of these zones can be given further consideration:
will trump their ability to manage in accordance with their own private interests. This fear—perhaps exaggerated by some—has, along with many other regional and global factors, accelerated the transition to more-intensive, fiber-maximizing management on private lands. We now have two highly differentiated forest management strategies: (i) federal forests managed for public values, albeit with few resources, and (ii) private forests managed intensively for fiber production. The latter seek to
uncertainty in which the prevailing social myths are collapsing. Enlightenment faith, with its emphasis on rationality and science, no longer integrates society. People have experienced a weakening of the central principles that guided their lives, resulting in confusion and disorientation. The sociologist James Aho (1997) referred to this crisis as the “apocalypse of modernity.” People found a firm sense of identity and confidence in the Enlightenment thinking and white, male Eurocentric culture
amount of money he or she would pay to have protection of a specific amount of a natural resource. Entire books have been written on the CVM (e.g., Mitchell and Carson, 1989). Besides describing CVM, these books evaluate the controversies regarding the accuracy or validity of the monetary amounts that people state they would pay in the surveys. Although CVM has been found to be quite accurate for measuring use values (Carson et al., 1996), until recently CVM surveys of passive-use values have
