Download or read book Successional Changes in Plant Species Diversity in Forest Chronosequences on Southern Vancouver Island British Columbia written by and published by . This book was released on 2009 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report presents current knowledge of the phytosanitary threats and potential risk-reducing measures associated with the global trade in forest commodities. Commodities discussed include: round wood, sawn wood, wood chips (treated and untreated), and plant parts and live propagative materials. As wood undergoes processing, its phytosanitary risks are generally reduced. For instance, greater phytosanitary risks are associated with international movement of round wood with bark. As bark is removed, and sawn wood is produced, the risks decrease significantly through this production process. Untreated and live forest products can present high phytosanitary risks. This review of commodity-based phytosanitary risks associated with the global movement of forest products provides the global phytosanitary community with scientific information regarding major pests associated with forest products and recommends effective approaches to mitigate associated risks."--Document.

This book was released on 2009 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increasing concern regarding species management and conservation in coastal forests of British Columbia, Canada, is how conversion of old-growth forests to managed forests affects the structure, function, and species diversity of ecosystems, and whether converted forests will eventually recover to a state that mimics many of the characteristic traits of old-growth stands. In this study, the authors investigated successional changes in vascular and nonvascular plant species diversity in the fragmented forest landscapes on southern Vancouver Island, British Columbia, using the chronosequence approach. They were particularly interested in understanding how the conversion of old-growth forests into secondary-growth forests would affect the plant-species diversity and what implications these results would have in terms of management in this region.--Document.

Available in PDF, EPUB and Kindle. Book excerpt: Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Available in PDF, EPUB and Kindle. Book excerpt: Big-Leaf Mahogany is the most important commercial timber species of the tropics. Current debate concerning whether to protect it as an endangered species has been hampered by the lack of complete, definitive scientific documentation. This book reports on vital research on the ecology of big-leaf mahogany, including genetic variations, regeneration, natural distribution patterns and the silvicutural and trade implications for the tree.
Download or read book Ex Situ Plant Conservation written by Center for Plant Conservation and published by Island Press. This book was released on 2013-02-22 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.
