Tree Harvesting Techniques


Book Description

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.



















Forest and Biomass Harvest and Logistics


Book Description

This book explains forest and woody biomass harvest, harvesting machines, systems, logistics, supply chain management, best management practices, harvest scheduling and carbon sequestration. It also covers applications of harvesting principles in forest and biomass management practices. The book provides an in-depth understanding of functions and applications of current and future harvesting technologies, the unique characteristics of harvesting machine with respect to cost, productivity, and environmental impacts. Special features include harvest machine illustrations and images of field operations, tabular presentations of filed studies of forest operations and detailed modelling processes for forest and biomass harvest logistics and supply chain management. Specifically, the book is designed for students, researchers, educators, and practitioners in the field of forest and biomass harvest and logistics. The book’s contents have been tested in teaching as the Harvesting Forest Product class for undergraduates and graduates in the Division of Forestry and Natural Resources at West Virginia University since 2000. The information contained in this book is a robust reference resource for students who would be future forest and biomass managers, timber contractors, entrepreneurs, researchers, and educators in the fields of forest and biomass operations, engineering, and resource management.




Tropical Forestry Handbook


Book Description

This book provides a cross-section of all outstanding experience in all fields of tropical forestry under a drastically changing environment induced by climate change. It sheds light on the existing know-how and presents it in a concise and efficient way for the scientist and professional in charge of planning, implementing and evaluating forest resources. The Tropical Forestry Handbook provides proven and/or promising alternative concepts which can be applied to solve organizational, administrative and technical challenges prevailing in the tropics. Presented are state of the art methods in all fields concerning tropical forestry. Emphasize is given to methods which are adapted to- and which safeguard - environmental conditions.







Farming the Woods


Book Description

Learn how to fill forests with food by viewing agriculture from a remarkably different perspective: that a healthy forest can be maintained while growing a wide range of food, medicinal, and other nontimber products. The practices of forestry and farming are often seen as mutually exclusive, because in the modern world, agriculture involves open fields, straight rows, and machinery to grow crops, while forests are reserved primarily for timber and firewood harvesting. In Farming the Woods, authors Ken Mudge and Steve Gabriel demonstrate that it doesn’t have to be an either-or scenario, but a complementary one; forest farms can be most productive in places where the plow is not: on steep slopes and in shallow soils. Forest farming is an invaluable practice to integrate into any farm or homestead, especially as the need for unique value-added products and supplemental income becomes increasingly important for farmers. Many of the daily indulgences we take for granted, such as coffee, chocolate, and many tropical fruits, all originate in forest ecosystems. But few know that such abundance is also available in the cool temperate forests of North America. Farming the Woods covers in detail how to cultivate, harvest, and market high-value nontimber forest crops such as American ginseng, shiitake mushrooms, ramps (wild leeks), maple syrup, fruit and nut trees, ornamentals, and more. Along with profiles of forest farmers from around the country, readers are also provided comprehensive information on: • historical perspectives of forest farming; • mimicking the forest in a changing climate; • cultivation of medicinal crops; • cultivation of food crops; • creating a forest nursery; • harvesting and utilizing wood products; • the role of animals in the forest farm; and, • how to design your forest farm and manage it once it’s established. Farming the Woods is an essential book for farmers and gardeners who have access to an established woodland, are looking for productive ways to manage it, and are interested in incorporating aspects of agroforestry, permaculture, forest gardening, and sustainable woodlot management into the concept of a whole-farm organism.
