:book: Abstract

Pyrenean oak (Quercus pyrenaica Willd.) is a Mediterranean forest species endemic to the Iberian Peninsula and is highly expanded in the Castilla and León region (Spain). Despite its potential in the wood industry, traditional uses and the lack of profitable management guidelines deteriorated its stands status, reducing the attention of owners and managers towards this species. This study explores the effects of different silvicultural scenarios on Pyrenean oak stands in transforming regular coppice stands into irregular high forests and in managing irregular stands based on a sustainable approach. Considering different criteria to ensure satisfactory forest conditions, predictions about key forest characteristics and various wood products were estimated to attract industry attention to the species’ potential. A clear need to adapt thinning periodicity, intensity, and criteria according to the local conditions of the stand was identified, requiring managers with expertise in irregular forest management. While numerical predictions may be biased, the trends observed under different management styles allow us to rank them according to the management objectives. Future work should aim to increase knowledge of irregular stand management and develop accurate tools to support managers on decision-making processes.
