A technique was developed to identify annual growth rings in E. grandis using a combination of annual measurements of diameter at breast height (DBH) from permanent sample plot (PSP) datasets and bark-pith density profiles. By assessing the pattern of radial variation in wood density within the context of the growth history of a compartment (by means of annual PSP data), it was possible to corroborate the estimation of annual growth rings on density profiles of E. grandis, especially closer to the bark-end.
