             abstract = "Coppicing is a low-cost management system which can ensure the 
                         wood productivity and consequently improve competitivity of 
                         Brazilian wood products. Stocking at the end of the first rotation 
                         is commonly used as a decision support criteria about coppicing or 
                         replanting the stand. However, the interactions of initial 
                         stocking and compensation practices (management of sprouts) over 
                         the productivity is yet to be understood. It is largely known that 
                         leaf area drives productivity, especially in young stands. From 
                         this perspective, unmanned aerial vehicles (UAV) could provide 
                         high quality imagery that can be used to assess canopy cover over 
                         areas subject to coppice regime and support management decisions. 
                         Therefore, our objective is to assess the effectiveness of this 
                         images in estimating canopy cover, as well as to check the 
                         relationships between canopy cover and productivity in a coppice 
                         experiment on a third rotation Eucalyptus grandis plantation at 
                         the S{\~a}o Paulo state. Sprout thinning was conducted 18 months 
                         after the clear cut of the previous rotation, the aerial imagens 
                         were taken 7 months after that, or 25 months after clear cut. 
                         Forest inventory was conducted one month after the survey in order 
                         to match the measurements. Although lower stocking plots were able 
                         to compensate canopy cover differences through individual stem 
                         increment, canopy cover were highly dependent on stocking 
                         (R2=0.71, p<0.001) and also highly correlated (R2=0.99, p<0.001) 
                         with stand production, these findings support the usage of aerial 
                         images to help management decisions.",
