The introduction of chain saws and tractors in the early 1950's marked the beginning of a change in tree harvesting techniques from the old manual methods to mechanized operations. It was followed by a rapid evolution both technically and systematically. Hence, the requirements for improved know ledge of operational efficiency also increased. Changing relations between Man, machines and environment brought about new experiences and awareness of a physiological and ergonomic nature. Improved knowledge of both machine technology and planning of work on a small or large scale has grown increa singly important for an efficient utilization of expensive machines and other equipment. The need for a textbook on tree harvesting techniques including expe riences made in recent years is enhanced. The book presented here is prima rily based on lectures given on the subject of Forest Techniques at the Faculty of Forestry at the Swedish University of Agricultural Sciences and after modifications also at the University of Nairobi (Kenya). Thus, the book is written primarily for students at the faculties and institutes of forestry. However, it is also useful for persons actively occupied in forest operations. The presentation of this book in its original Swedish version in 1972 created a considerable interest in the preparation of a condensed edition in English. Thus interest has been expressed in Finland, Norway, Holland, Canada, U.S.A., Brazil, Japan, Poland, Scotland and Yugoslavia.

Positive Impact Forestry is a primer for private woodland owners and their managers on managing their land and forests to protect both ecological and economic vitality. Moving beyond the concept of "low impact forestry," Thom McEvoy brings together the latest scientific understanding and insights to describe an approach to managing forests that meets the needs of landowners while at the same time maintaining the integrity of forest ecosystems. "Positive impact forestry" emphasizes forestry's potential to achieve sustainable benefits both now and into the future, with long-term investment superseding short-term gain, and the needs of families -- especially future generations -- exceeding those of individuals. Thom McEvoy offers a thorough discussion of silvicultural basics, synthesizing and explaining the current state of forestry science on topics such as forest soils, tree roots, form and function in trees, and the effects of different harvesting methods on trees, soil organisms, and sites. He also offers invaluable advice on financial, legal, and management issues, ranging from finding the right forestry professionals to managing for products other than timber to passing forest lands and management legacies on to future generations. Positive Impact Forestry helps readers understand the impacts of deliberate human activities on forests and offers viable strategies that provide benefits without damaging ecosystems. It speaks directly to private forest owners and their advisers and represents an innovative guide for anyone concerned with protecting forest ecosystems, timber production, land management, and the long-term health of forests.

A chance encounter with a fallen tree started professor and amateur woodworker Samuel Sherrill thinking: Is there a better way to stretch our precious natural resources? The question led to the writing of Harvesting Urban Timber. Sherrill explains how to identify potential urban timber, how to safely harvest it and convert it into useful lumber.

The principles and practices for forest harvesting in Indonesia (2000) have been developed to provide a uniform set of minimum standards for logging practices in the production and limited production forests in Indonesia. The provide the standard for WHAT is involved in planning and implementing logging activities in natural forest and WHY certain operations should be undertaken. The Reduced Impact Logging (RIL) guidelines for Indonesia provides the mechanism for HOW the standards will be applied in the field or “how to do the work”. Tractor skidding–mostly by crawlers and skidders–is the most common system (ca. 90%) used in the Indonesian Selective Cutting and Planting (TPTI) System. Considering the fact that familiarity with more environmentally friendly logging system (such as cable and aerial logging) is still lacking in Indonesia, often due to cost, etc., RIL guidelines focus on ground-based harvesting which can be implemented in the lowland and hill forests in Indonesia. Target groups of this guidelines are production supervisors, RIL planners, bolck inspectors, road network planners, road construction supervisors, machine operators, chainsaw operators, tractor operators and their assistants.
