Multi-objective forest landscape management based on expert opinion in Northeastern Portugal
Forest management planning is a complex process of defining and coordinating forest management activities according to particular goals and objectives. Spatial heterogeneity, either resulting from environmental variability and disturbance or from societal variables (ownership, governance, preferences), contributes to increase the complexity of management problems and the solutions that can be found for particular targets. The trend to address several ecosystem services simultaneously as management criteria and objectives accounting for the way these vary in space, make the process even more complex. Tools to integrate this diversity of conditions, criteria and objectives have received strong interest in recent years and several applications are now available in academic and professional environments in several parts of the world. In the region of Bragança, North-eastern Portugal, operational research tools recently developed with the goal of increasing management and wood mobilization in the local forest sector, allow ecosystem services to be addressed from heuristics, multi-criteria and multi-objective perspectives. In this study we addressed the management of maritime pine stands in the region of Bragança to optimize the supply of timber, water and mushrooms. For that we used a modified version of the forest management decision support system tool AppTitude®, based on a heuristic approach and combining forest growth and yield dynamic models, expert opinion and multi‐criteria decision making methods on a spatially explicit basis. The tool considers supply, demand and supply-demand interactions for timber, water yield and mushrooms in forest stands. It considers also user-defined scenarios that are based on constraints and limits (minimum and maximum) to find the best solutions for the supply of the three ecosystem services addressed. Expert opinion was used in the valuation of maritime pine wood from the point of view of the industry demand, mushrooms production and water yield, based on questionnaires build ...
