Beschreibung
Harvesting includes all the activities to fell trees and remove them from the forest to the roadside for loading and transport from the forest. Harvesting and extraction operations are the activities that generally cause the most significant impacts on forest managed for timber production. Sustainable forest mana- ment is concerned with management of forests in such a way as to control the impacts associated with harvesting and timber extraction. Harvesting and extraction for sustainable timber production in natural forests are not to be confused with logging associated with land conversion activities such as c- version to permanent or temporary agriculture, pasture land, or domesticated trees. Much of the impact of harvesting and extracting can be reduced through proper planning and control of harvesting operations using principles, s- tems, and techniques common to temperate forests. However, many areas of the tropics pose unique operating conditions: heat, high humidity, hi- intensity precipitation, occurrence of certain diseases, and lack of rock for su- able road surfacing. In natural forests, clear felling is rarely practiced, and many species are the rule with few commercial species on any hectare; thus, log removals per unit area are low.

Über den Autor

John Sessions is University Distinguished Professor and Stewart Professor of Forest Engineering at Oregon State University. His forestry career spans five decades, forest operations on five continents, including experience in each of the main tropical forest regions. He has demonstrated logging methods in Jamaica, was harvesting manager in the Amazon, conducted reduced impact logging evaluations in Malaysia, transportation planning workshops in Africa and logging feasibility studies throughout tropical Latin America from Costa Rica and Colombia to northwest Argentina. He is joined by coauthors who have a combined experience in more than 60 countries.

Zusammenfassung
This book brings together information on harvest methods, system productivity, and methods for conducting safe, efficient, and environmentally acceptable operations in tropical forests. It highlights the challenges of harvest operations in the tropics, includes techniques that have been shown to be successful, and discusses newer technologies. The book is a reference for those interested in planning and management of tropical forests. Numerical examples are provided to provide clarity for interpreting graphs, procedures, and formulas. The book covers harvest systems from planning for felling to log transport from the forest, and concludes with considerations in selecting the appropriate harvesting technology.
