Download or read book Ecology and Management of Sitka Spruce written by N. Merle Peterson and published by UBC Press. This book was released on 2011-11-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

Download or read book In a Dark Wood written by Alston Chase and published by Routledge. This book was released on 2017-07-12 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a Dark Wood presents a history of debates among ecologists over what constitutes good forestry, and a critique of the ecological reasoning behind contemporary strategies of preservation, including the Endangered Species Act. Chase argues that these strategies, in many instances adopted for political, rather than scientific reasons, fail to promote biological diversity and may actually harm more creatures than they help. At the same time, Chase offers examples of conservation strategies that work, but which are deemed politically incorrect and ignored. In a Dark Wood provides the most thoughtful and complete account yet written of radical environmentalism. And it challenges the fundamental—but largely unexamined—assumptions of preservationism, such as those concerning whether there is a "balance of nature," whether all branches of ecology are really science, and whether ecosystems exist. In his new introduction, Chase evaluates the response to his book and reports on recent developments in environmental science, policy, and politics. In a Dark Wood was judged by a recent national poll to be one of the one hundred best nonfiction books written in the English language during the twentieth century. A smashing good read, this book will be of interest to environmentalists, ecologists, philosophers, biologists, and bio-ethicists, and anyone concerned about ecological issues.
