6.4. Implementing quality: CarryingcapacitiesforvisitormanagementUp to now, there is very little known about the carrying capacity of natural reserveswhen it comes to tourism an its activities in areas of high biodiversity.Very little scientific research is done so far to deal with the effects of intensivetouristic use of natural reserves.Park managers within the DANUBEPARKS Network do feel very uncomfortableand do have a great lack of knowledge on the impact of tourism on species andhabitats in their parks. The question is not only if tourism is already causing problemsto the parks, but where are future perspectives to improve and boost tourism in theparks without endangering its value.Nature tourism is on of the most important fields for the parks to show theirpotentials to the public and to stakeholders and to improve and foster environmentaleducation.To know about the impact of tourism on species an habitats in the protected area isone of the most important things to do a proper management.
