As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

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.
