|In the counties of the European Community the influence of European directives is increasing. Especially the directive on the conservation of natural habitats and of wild fauna and flora (European Council Directive 92/43 EEC from 1992) and the directive on the conservation of wild birds (European Council directive 79/409 EEC from 1979) are expected to have an influence on the development of nature-based sport. Most of the sport organizations in Germany are expecting negative consequences for their future development concerning nature-based sport in mountain areas. Based on a study of the German sport association possible consequences are analyzed and discussed. This project gives guidelines for the application and interpretation of these directives, the practicable use and management. The study shows that concerning a possible deterioration three types of sport and recreational activities have to be differentiated. Further more sport events must be evaluated in the future. At least the role and task of the management plan for NATURA 2000 areas is discussed. The management plan helps to choose suitable measures, helps to solve conflicts and to rise the acceptance and transparency for the public. It is demonstrated that the consultation and participation of local people including members of sport and recreational organisations is necessary to reach the best result for the nature conservation and conservation of endangered habitats or species.
