The need to reduce costs involving the harvesting process spurred the search for advanced and more efficient technologies. In addition, over the past decades, awareness for the preservation of natural resources increased significantly throughout the world. This study aimed to identify and evaluate qualitative and quantitatively the main environmental impacts from the harvesting process in the harvester and forwarder subsystem held in promoted properties, seeking to outline possible mitigation measures or potentiating. For this we used a magnitude scale and a questionnaire was applied to experienced employees in forest encouragements in the state of Santa Catarina and Paraná. Through a descriptive checklist impacts were discussed and evaluated qualitatively and through the intersection of reversibility of the impact with the outcome of magnitude was obtained its importance value. The impacts in the anthropic half proved to be of greatest importance in the study because despite the reduced number of related impacts these had the highest magnitude values and importance. The physical environment presented high occurrence of average importance of impacts, requiring attention also because of having strategic control impacts that prevent the occurrence of other environmental damage. The biota was less concern with the predominance of low magnitude impacts, reversible and of minor importance. Most impacts showed up negative, direct order, regional territorial coverage, which occur in short-term, permanent and / or indefinite term and are reversible with the possibility of use of the mitigation measures or potentiating.
