Management and monitoring of visitor flows in recreational and protected areas are topics of growing importance worldwide. Today more than 100,000 protected areas exist globally, and the trend shows that their number is increasing, as the IUCN statistics demonstrate. To these, we must add numerous smaller areas that also have special natural or cultural heritage values, but do not have a special protected status. Many of these areas do not only serve the protection of natural and cultural values or biodiversity, they are also important points of attraction for tourism and recreation. These areas must be professionally maintained and managed if they are to conserve their natural and landscape values in future.
