|Description: ||This research evaluated the quality of forest harvest using chainsaw, in farms in the south of Espirito Santo state, Brazil, considering aspects of quality and loss of wood left in the strains. A total of 250 m² plots were launched to collect data of forest cut with chainsaw, for evaluating the quality of the cut related mto: presence of skewers; crack damage; strains burst range nonstandard; strains without the notch directional, and the remaining height of the strain, in order to measure the loss of wood held in the strains. The main results were: the spike was present in 21.9% of the strains, the cracks in 17.2% of the strains, non-standard strains in 44.6% of them and unnotched directional strains in 34.5% of the evaluations. To check the influence of the realization of the directional notch on the height of the strains t-test, at 5% probability, has shown that there is an increased contribution to height of the strains, where the cut was made without the directional notch. The amount of wood held in the strains above the recommended maximum was, on average, 2.43 m³.ha-1, representing a loss of R$ 172.53 ha-1. It was verified that the loss of timber remaining in eucalyptus strains was higher in places where, for the logging, there was not done the directional notch. The items evaluated showed uneven quality, indicating the need to improve cutting with chainsaw.|
