Download or read book Domestication of Radiata Pine written by Rowland Burdon and published by Springer. This book was released on 2017-12-12 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: In nature, radiata pine is very localised and an obscure tree species despite the romantic character of much of its natural habitat. That obscure status and the lack of any reputation as a virgin timber slowed its due recognition as a commercial crop. Nevertheless, it has become a major plantation forest crop internationally. It has become the pre-eminent commercial forest species in New Zealand, Chile and Australia, with important plantings in some other countries. It consequently features prominently in the international trade in forest products, in addition to its importance in domestic markets of grower countries. Very fast growth, considerable site tolerances, ease of raising in nurseries and transplanting, and ease of processing and using its wood for a range of products and purposes, have made it the utility softwood of choice almost everywhere it can be grown satisfactorily. Abundant genetic variation and its amenability to other management inputs created special opportunities for its domestication. The story of its domestication forms a classic case history in the development of modern commercial forestry, with trailblazing in both genetic improvement and plantation management; this inevitably meant a learning process that provided instructive lessons, especially for tree breeders dealing with some other species. Paradoxically, the plantation monocultures have played and can continue to play an important role in protecting natural forests and other forms of biodiversity. Given the attractions of growing radiata pine, there were inevitably cases of overreach in planting it, with lessons to be learnt. Economic globalisation has meant globalisation of pests and disease organisms, and the scale on which radiata pine is grown has meant is has been the focus of various biotic alarms, none of which have proved catastrophic. Temptations, remain, however, to pay less than due attention to some aspects of risk management. The chapter structure of the book is based on historical periods, beginning long before any important human influences, and ending with a look into what the future might hold for the species and its role in human and ecological sustainability. Almost throughout, there has been complex interplay between the technical aspects, local social and economic factors, various types of institution, the enthusiasm and drive of some very influential individuals, and tides of economic ideology, threads that needed to be woven together to do the story justice.

Download or read book Rethinking Invasion Ecologies from the Environmental Humanities written by Jodi Frawley and published by Routledge. This book was released on 2014-02-24 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research from a humanist perspective has much to offer in interrogating the social and cultural ramifications of invasion ecologies. The impossibility of securing national boundaries against accidental transfer and the unpredictable climatic changes of our time have introduced new dimensions and hazards to this old issue. Written by a team of international scholars, this book allows us to rethink the impact on national, regional or local ecologies of the deliberate or accidental introduction of foreign species, plant and animal. Modern environmental approaches that treat nature with naïve realism or mobilize it as a moral absolute, unaware or unwilling to accept that it is informed by specific cultural and temporal values, are doomed to fail. Instead, this book shows that we need to understand the complex interactions of ecologies and societies in the past, present and future over the Anthropocene, in order to address problems of the global environmental crisis. It demonstrates how humanistic methods and disciplines can be used to bring fresh clarity and perspective on this long vexed aspect of environmental thought and practice. Students and researchers in environmental studies, invasion ecology, conservation biology, environmental ethics, environmental history and environmental policy will welcome this major contribution to environmental humanities.

This book was released on 2011-02-24 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout all ages, the activities of mankind have weighed heavily upon the environment. In turn, changes in that environment have favoured the rise of certain social groups and limited the actions of others. Despite this, environmental history has remained a 'blind spot' for most social and economic historians. This is to be regretted, as the various and unequal effects of environmental change often explain the strengths and weaknesses of certain social groups, irrespective of their being defined along the lines of class, gender and ethnicity. This volume brings together the expertise of social and environmental historians in an effort to assess the extent to which transnational agents changed socioecological space as a consequence of globalization since the Late Middle Ages.

Book excerpt: Pines are the most economically important group of trees in the world, covering large parts of the Northern Hemisphere and also being of silvicultural significance in many countries in the Southern Hemisphere. This book is compiled from 65 datasheets on pine from the Forestry Compendium Global Module (published by CABI on CD-ROM). For each species, there is information on common names, taxonomy, botanical features, natural distribution, latitude range, climate, soil properties, silvicultural characteristics, pests, wood and non-wood products.
