Brazil is one of the largest producers and exporters of forest-based products in the world, and mechanized forest harvesting is responsible for a large part of the final cost of the wood that supplies the forestry industry. Mechanized Forest Harvesting in Own and Outsourced Modules was developed at a renowned federal teaching institution in the country, based on data provided by one of the largest multinationals in the pulp sector. It provides an objective and integrated approach to the various stages of mechanized forest harvesting within the wood supply process. The way in which the subject is dealt with gives the reader a dynamic view of the mechanization of forest harvesting and its operational particularities by comparing yields during execution, whether the harvester is self-owned or outsourced.
