REGO, Francisco Castro; MONTEIRO, Maria do Loreto; GERALDES, Altino  and  MESQUITA, Jorge. Silviculture of Quercus pyrenaica and Q. rotundifolia Mixed Stands: the Case of Tapada da Nogueira. Silva Lus. [online]. 2011, vol.19, n.2, pp.135-148. ISSN 0870-6352.

Based on the Forest Inventory plots of Tapada da Nogueira, located in Bragança region, the analysis of mixed stands of Quercus pyrenaica and Q. rotundifolia was performed. In this zone, these two most abundant species have variable area stands. The measurements' results indicate a predominance of small diameters (in both species), the class of 10cm diameter at breast height (dbh) exhibiting the larger frequency. Especially in Quercus pyrenaica stands there are very few individuals with a Dbh higher than the class of 20cm, so the basal area of the stand seems low when compared with the 20m²/ha values presented by CARVALHO (2005). Flexible models of space organization, in which the unit may either be an individual or a larger stand, allow the prediction of a variety of interesting combinations of composition and regime. These models aiming forestry timber production may be associated with other uses of non-wood production such as deer hunting, in this case made possible by the walled area of the Tapada.

Keywords : Mixed stands; forestry models; Q. pyrenaica; Q. rotundifolia.
