Roelof A. A. Oldeman Tropical hardwoods are one of the essential cogs in the complex socio-economic machinery keeping alive an ever-increasing humanity with steadily rising claims upon a finite-resource environment. Their position in this context at first sight seems to be analogous to that of other commodities, such as rubber, metals, mineral oil, tropical fruits and many more. Looking closer, however, tropical hardwoods occupy a special place. Their vast majority, unlike tropical crops, still comes forth from natural forests being exploited by man. This exploitation straight from the natural resource is something they have in common with oil and metals, but the fact that they grow in living systems places them closer to crops. Natural forest ecosystems are not renewable. Timber producing trees, however, can be made into a renewable resource on condition that ways and means are found to cultivate them as a crop. be understood as a socio-economic The tropical hardwood situation can best chain, with the resource base at one end, the consumer community at the other and everything that has to do with the market in the middle. Now, at the resource side, the economics of tropical hardwood extraction barely got out of the primeval ways of wood-gathering by hand and by axe, which were still predominant in the nineteen-forties. There, the offer of natural products was so immense and so near to hand that no care had to be taken of the resource.

For 75 years, few textbooks have served a topic as well as Introduction to Forests and Renewable Resources. Widely recognized for its comprehensive yet engaging coverage, this major revision provides an outstanding, up to date overview of management issues, conservation policies and practices related to forests and renewable resources, and an authoritative perspective on how these topics are evolving. New directions are covered, including: green certification of forest management and wood products; improved harvest practices in response to public concerns; carbon sequestration and ecological services as important forest yields; ecosystem restoration and resilience as management responds to concerns about global warming; and more. Well-illustrated with new examples, case studies and abundant photos, this eighth edition describes the importance and history of forests, evolution of policy, North American distribution of forests, and moves on to describe forest health strategies to combat insects, disease, damage from mammals, and fire. Ecological principles are explained as basis for forest management, with chapters on management of the associated resources of wildlife, watersheds and streams, range resources, outdoor recreation and wilderness. Market concerns and technology are embraced in chapters on economics, measurement and analysis, harvesting, and forest products. Concluding chapters describe management of forests and renewable resources by the federal government, by states, by private land owners, and in urban areas and communities. For forestry, natural resource, and environmental science students, involved citizens and resource users and professionals, this book is your reference and guide to forests and renewable resources.
