| Harvest scheduling models consider traditionally a single silvicultural alternative to provide the optimal timber production in each case study. However, several silvicultural strategies and alternatives have been proposed to integrate additional criteria, contributing to the current idea of multifunctionality associated with the management of forest systems. In many cases, such purpose is achieved by modifying harvesting systems, reducing the areas affected by final cuts and leaving parts of the forest perpetually uncut. With the progressive incorporation of silvicultural strategies into timber harvest scheduling models is likely that more attractive solutions can be obtained for the stakeholders compensating the greater complexity in the modeling process. In this study, seven possible silvicultural treatments are proposed within a multi-criteria model including among them the possibility of no management as an indicator of biodiversity conservation. We deal with this issue by analyzing a case study in Central Spain, where several protection figures are considered. It is also relevant to note that a significant part of the forest has been recently declared a National Park (where commercial cuts have been forbidden). This fact implies several changes in the business-as-usual treatment traditionally used. In this study, an attempt has been made to define a broad and realistic set of possible silvicultural strategies to be applied a priori according to the characteristics of each forest stands, in order to choose the best alternative in each stand according to different criteria and constraints. In this way, productive, technical and environmental criteria have been considered over a 100-year planning horizon. It should also be noted that through an interactive process the preferences of the forest managers will be integrated into the decision making process. The results show how the hybridization of different silvicultural strategies within a multiple criteria decision-making context provides more appealing solutions to the forest managers. | |
