Abstract
The need to increase forest enterprises productivity has demanded higher levels of mechanization. The objective of this study was to evaluate the suitability of areas in Espírito Santo State to implement mechanized wood harvesting using short log system. To prospect suitable areas for mechanization, algebra map of Eucalyptus edaphoclimatic zoning, land use and occupation, slope, conservation units and their respective buffer zones was performed. Thus, suitability zones were defined based on edaphoclimatic conditions for evaluated species, with temperatures between 19 and 26ºC, water deficit from 30 to 210 mm and annual average rainfall between 900 and 1800 mm defined as suitable. Land use and occupation was classified as fit, fit with type II limitation, fit with type III limitation and unfit. For slope classes, three categories were created: fit (0 - 27º), fit with limitation type I (27.1 - 35º) and unfit (> 35º). Results showed that State has 39.45% of its entire area able to implement mechanized wood harvesting for Eucalyptus and 47.91% is unfit. With results, authors concluded that Northeast micro-region stood out with large areas suitable for Eucalyptus harvest mechanization and employed methodology has potential for use and adaptation in other study areas around world.
