Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension of ecosystem services, despite being considered a research priority. We examined how ecosystem service bundles and trade-offs emerge from diverging social preferences toward ecosystem services delivered by various types of ecosystems in Spain. We conducted 3,379 direct face-to-face questionnaires in eight different case study sites from 2007 to 2011. Overall, 90.5% of the sampled population recognized the ecosystem’s capacity to deliver services. Formal studies, environmental behavior, and gender variables influenced the probability of people recognizing the ecosystem’s capacity to provide services. The ecosystem services most frequently perceived by people were regulating services; of those, air purification held the greatest importance. However, statistical analysis showed that socio-cultural factors and the conservation management strategy of ecosystems (i.e., National Park, Natural Park, or a non-protected area) have an effect on social preferences toward ecosystem services. Ecosystem service trade-offs and bundles were identified by analyzing social preferences through multivariate analysis (redundancy analysis and hierarchical cluster analysis). We found a clear trade-off among provisioning services (and recreational hunting) versus regulating services and almost all cultural services. We identified three ecosystem service bundles associated with the conservation management strategy and the rural-urban gradient. We conclude that socio-cultural preferences toward ecosystem services can serve as a tool to identify relevant services for people, the factors underlying these social preferences, and emerging ecosystem service bundles and trade-offs.

Protected areas are the main strategy for the protection of ecosystems and biodiversity. However, changes occurring during the Anthropocene continue to threaten biodiversity and, therefore, the associated ecosystem services that maintain human well-being. Despite efforts to integrate protected areas into a wider landscape, most of these areas are still managed as islands within a matrix of degraded territory; there is no clear conceptual framework that integrates them into the surrounding landscape. We first review the evolution of the protected-area concept. Then, we acknowledge the main limitations that protected areas face for long-term conservation. Next, we discuss how the ecosystem service approach could overcome some of these protected-area limitations. Finally, we propose a social–ecological approach for protected areas to maintain high biodiversity and its associated flow of ecosystem services in the context of uncertainty.
