Produce wood, preserve the environment, provide social services: all these goods and services are expected of the forests nowadays. Forests can sustainably produce them, but how much? These products are joined outputs in a production process composed of forest growth and management. Therefore, it is important to characterize how outputs are joined to set production goals. In this paper, we simulate alternative management scenarios for Quercus petraea even- aged high forest at the stand scale. Then we estimate for each scenario the production of three goods and services: 1) the production of wood in terms of the net present value of an infinite series of rotations (NPVIS); 2) the preservation of biodiversity, using an indicator of the number of bird species potentially present in the forest (Bio); 3) the production of a recreation service, in terms of attractiveness for recreational activities (A). Lastly, we determine production possibility frontiers for the three two-output combinations. We show that NPVIS and Bio or NPVIS and A are substitute products of forest management, but there are possibilities for producing both in the same forest. Bio and A are compatible to a certain extent. The methodology employed seems efficient to study multi-functionality at the stand level.
