This study aims to explore the use of the social-ecological system (SES) in tourism of a mountain area. Authors examined residents’ perceptions of tourism impacts on four SES aspects: ecosystems, local knowledge, people and technology and property rights institutions. The aim is to find area that will be a “common ground” for community and area that can be a source of conflict and will require additional work to solve the differences. Second objective was to examine residents’ perception towards future local development tourism policies (winter tourism, seasonality and environment and culture) and how those policies can affect natural, socio-economic and cultural aspects of mountain area. Residents’ perceptions of sustainable tourism development potential, perceived tourism impacts, analysis of community attachment and employment sector of stakeholder were involved in this study. The authors applied the Q-methodology, as one SES-allied approach, in a small mountain community of Kopaonik, the Republic of Serbia. The results revealed that residents’ agreement/disagreement is connected with two aspects: ecosystem and property rights and that ecosystem can be significantly influenced by all three development policies. Findings suggest that development of future natural conservation plans and new cultural attractions can have positive effects on all parts of social-ecological system. Some practical implications of those findings for tourism planning and development are also discussed.
