The Tatra Euroregion is a non-governmental organization which has actively and professionally implemented various trans-frontier operations in the shared Polish- Slovak borderland for the last 15 years. The Euroregion has well-functioning organizational structures. Since 1999, the Euroregion has managed European funds for the development of the Polish-Slovak borderland, enabling the implementation of the constitutional aims and assignments of the Euroregion. Cooperation in social and cultural fields is constantly among the prominent activities of the organization. This kind of collaboration is crucial for the borderland's evolution. It provides an effective environment for economic growth and pro-ecological activities, which are still not sufficiently developed here. An important step in the modernization of the Euroregions is the establishment of the 2008-2015 strategy. An organizational transition into the European Grouping of Territorial Cooperation is planned for the near future.
