Abstract: One of the key challenges in designing agri-environmental schemes targeted at conservation is the determination of the amount of financial resources that should be allocated towards a particular aim such as the conservation of an endangered species. Economists can contribute to an answer by estimating the 'optimal level of species conservation'. This requires an assessment of the supply and the demand curve for conservation and a comparison of the two curves to identify the optimal conservation level. In a case study we estimated the optimal conservation level of Large Blue butterflies (protected by the EU Habitats Directive) in the region of Landau, Germany. The difference to other studies estimating optimal conservation is that a problem was addressed where costs and ecological effects of conservation measures are heterogeneous in space and over time. In our case study we found a corner solution where the highest proposed level of butterfly conservation is optimal. Although our results are specific to the area and species studied, the methodology is generally applicable to estimate the amount of financial resources that should be allocated to conserve an endangered species in the context of agri-environmental schemes.
