This project deals with the trade-offs of biodiversity conservation and tourism within a national park, taking stakeholder interests into account in a bioeconomic model. The ecological system is described by a predator/prey system augmented by visitor impacts and constitutes the constraint within a dynamic optimal control model. The decision maker’s objective describes the intertemporal trade-offs between species protection and use- and non-use values for visitors (beautiful landscape, visitor infrastructure, species protection). Three case studies are investigated for the Hohe Tauern national park (Austria), one for the charismatic golden eagle, another for the non-charismatic but endangered rock partridge and a third one for the charismatic alpine ibex. The ecological parameters are estimated by a GIS model, visitor marginal valuation is elicited by a WTP survey. In the optimal control model, different protection measures and tourism programs are tested and optimal dynamic policy strategies and mixes thereof are highlighted. It is shown under which conditions visitor demand can be used to generate conservation budgets necessary for species protection.
