		<abstract>The control of wood extraction in the Amazon has been a complex task for the Environmental Agencies. Verification in the field demands a considerable technical effort. Time, financial and human resources are limiting factors. On the other hand, the Remotely Piloted Aircraft Systems (RPAS) emerges as a new technology capable of revolutionizing forest monitoring by enabling the monitoring of selective logging in large or difficult to access areas. This study aimed to evaluate the usefulness of RPAS in monitoring logging areas authorized by the Brazilian Forest Service, the federal forest concessions. This study was conducted in July 2014 in the municipality of Itapuã do Oeste, Rondônia state, Brazil, in the yard of the Madeflona sawmill, using an electric propulsion, fixed-wing RPAS equipped with a digital RGB camera. The results were promising. A difference of only 2% (or 32 m3) was recorded between the RPAS estimated volume of wood in log stacks (1,534.38 m3) and the volume declared by the company on the day of the experiment (1,502.11 m3). This new methodology, even on an experimental basis, may replace and/or supplement in the near future the survey in the field, adding a greater agility and precision to forestry estimates.</abstract>
