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.
This handbook provides a comprehensive overview and cutting-edge assessment of community forestry. Containing contributions from academics, practitioners, and professionals, the Routledge Handbook of Community Forestry presents a truly global overview with case studies drawn from across Africa, Asia, Europe, and the Americas. The Handbook begins with an overview of the chapters and a discussion of the concept of community forestry and the key issues. Topics as wide-ranging as Indigenous forestry, conservation and ecosystem management, relationships with industrial forestry, trade and supply systems, land tenure and land grabbing, and climate change are addressed. The Handbook also focuses on governance, looking at the range of approaches employed, including multi-level governance and rights-based approaches, and the principal actors involved from local communities and Indigenous Peoples to governments and national and international non-governmental organisations. The Handbook reveals the importance of the historical context to community forestry and the effects of power and politics. Importantly, the Handbook not only focuses on successful examples of community forestry, but also addresses failures in order to highlight the key challenges we are still facing and potential solutions. The Routledge Handbook of Community Forestry is essential reading for academics, professionals, and practitioners interested in forestry, natural resource management, conservation, and sustainable development.

The Tree Faller’s Manual is an essential handbook for forest operators and others who need to fell trees manually using a hand-held chainsaw. This manual builds on the information provided by the Chainsaw Operator’s Manual. Tree felling is a high risk activity. Many fatalities and serious injuries have occurred as a result of being struck by falling trees, dislodged tree limbs or other dangers in the area. Most of these accidents are caused by using unsafe felling techniques and not following safe work procedures. This manual will guide the faller to safer work techniques. The manual is based on the national competency standards for the forest and forest products industry where tree-felling is covered using three categories: basic, intermediate and advanced. Basic tree felling applies to trees that are relatively small, with a single stem and no defects. Intermediate tree felling covers trees with single or multiple stems, limited defects, and lean and weight distribution that can be adapted to felling direction. Advanced tree felling applies to larger and more complex trees and includes trees deemed to be more hazardous. Workplace safety, risk assessment and site preparation are included along with the theory, techniques and tools for each of the tree-felling categories.
