... almost 30000 ha of Pinus nigra stands [4, 5]. The dif- ference between the predicted and observed fire probabilities in stands dominated by Pinus pinaster and Pinus pinea can be explained by the small ... model for forest stands in Catalonia pre- sented in this study opens many possibilities to integrate the risk of fire into forest management planning and decision-making. The...
