The present thesis tries to accomplish an acceptance analysis of the „High Alps Nature Park Zillertal Alps“ - comprising the localities Mayrhofen, Brandberg, Tux, Finkenberg and Ginzling - as well as of its planned expansion area. The protected area is located in the Ziller Valley in the Austrian federal state Tyrol, which is an illustrative example of conflictive regional developments in the Alpine area.The chosen scientific methods aim to find out about local peoples attitudes and perceptions towards the Nature Park in general, the professional staff, their working fields, projects and the planned expansion area. Furthermore, this is considered to be interesting in the light of whether the attitude of acceptance has changed since the regulation of the protected area.Methodological approaches such as comprehensive literature research with a priority of regional sources provided the framework for the following analysis. The acceptance analysis was performed by means of quantitative interview techniques. The evaluation of the personal interview, carried out by using questionnaires in summer/autumn 2014 within the Nature Park localities, revealed the desired results which were then compared with two preliminary studies. The thesis also focuses on five professional interviews. The empirical findings indicate an increasingly positive development on a variety of grounds. Whilst criticisms existed concerning protected areas initial stage, preceding and actual results reflect the continuous improvement of acceptance towards the Nature Park and its expansion area. It must be noticed that the significance of gentle tourism, awareness raising, sustainability and environmental education has increased. The continuous integration of the Nature Park in existing structures of the region can be expected, on condition of an active implementation and continuation of main fields of work as well as an extension of networks in the region.
