Abstract in English
Virgin cork production estimates resulting from young cork oak stands thinning and
Cork oak's juvenile stage precedes the first income obtained from cork
production during the exploitation of the Quercus suber forest. This is obtained with the
first cork extraction, where virgin cork, with low commercial value, is obtained. In recent
plantations, some made with considerable high tree density values, it is frequent the

need of thinning operations during the juvenile stage, as a way of selecting trees, and
diminish the number of trees per hectare. During these thinning operations, frequently
made simultaneously to the stand first debarking, big amounts and varieties of wood and
virgin cork are produced. With this work, a methodology for quantifying the amounts of
virgin cork originated on a thinning operation is proposed, which depends exclusively
on the diameter at breast height measurement.
