The objective of this paper was to quantify the volumetric and economic losses after clearcutting interventions in the mechanized forest harvest of Pinus taeda L. The study was carried out in a forest company in which the harvesting system of short logs is used in the mechanized modules. Different assortments were analyzed considering the dimensions and price marketed. The volume of the logs left in the field after the intervention was measured with Smalian method. The downgrade coefficients were determined for each assortment by dividing the percentage of the real volume by the assortment and the percentage of volume estimated by the assortment, and the economic losses generated. It was verified that the percentage of logs in the WPP assortment represented approximately half of the losses, followed by the PV01 assortment. The greatest losses in volume occurred in PV01 assortment and in monetary terms it occurred in the PV02 assortment.
