Following the paradigm of the dynamic-innovative approach, large-scale protected areas are not only appreciated as classical instrument for nature conservation, but also an integrative component of the surrounding region. Depending on the focus and category, large-scale protected areas have set as their objectives to develop the region sustainably through their activities.For the study about the usage of large-scale protected areas for sustainable development the Limestone Alps National Park Region in Upper Austria is used. At first the initial situation according to socio-economic and other criteria is analysed, followed by the working out of alternative scenarios for the future development. Qualitative expert interviews are conducted as an empirical method for the study of the individual scenarios potential. The elaborated scenarios are contrasted using a SWOT-analysis and key factors for a deductive evaluation.The results clarify that in this region improved collaboration of all stakeholders and a comprehensive recognition of the mutual benefits of the National Park and the region are prerequisites for a sustainable development in the future. Due to the local economys structure, diverse interests or unrecognized opportunities the previously used instruments to support the region were partly not able to develop all their impacts. For an identification with the National Park in the entire region a regional restructuring is appropriate. This includes also cooperation beyond administrative or perceived boundaries. Therefore, the next in size regional level, the Steyr-Kirchdorf region, is primarily suitable as a space to create a joint identity. As a long-term vision to achieve regional sustainability, the UNESCO biosphere reserve concept is worth considering as an organisational framework for the enlarged region.
