Abstract
This paper describes the first part of a study on the possibilities of silvicultural management of mixed pine (Pinus sylvestris L., Pinus pinaster Ait. and Pinus nigra Arn.) and oak (Quercus pyrenaica Willd.) stands in Middle Spain. These mixed stands are the result of transformation plans of the 60-70s from oak coppice-stands in pine stands. The first research step was the typification of this forest by stand quality (site index + stem quality), percentage and type of mixture into mixed forest subtypes. Through 30 experimental plots stand structure, stem quality and vitality of the oaks were studied. The stands are characterized by a high percentage of oak in the dominan layer (40-50 p. 100), principally good site qualities by oak and a sufficient percentage of well formed stems for production of saw timber. This results points out the importance of concieving diferentiated silvicultural management systems, in order to adapt the practical management to real site conditions, as well to diverse percentages, distribution and quality of mixed species.Downloads
