National Parks are usually the only protected areas with their own management and its main task is the protection of the entire area on its territory.

In order to proclaim an area a national park several conditions should be taken into account. 

- a large area of extraordinary natural beauty

- the nature has to maintain its original qualities, it should not be ruined or endangered by doings of man

- multiple natural phenomena( phenomena should not only be geomorphologic or solely botanical - otherwise they are measured by other standards of protection)

According to international standards an area at least 20 square kilometers in size is required, out of which 10 square kilometers of nature should be completely preserved and protected. Isolated islands are exempt from this rule. This criterion is necessary since it is hardly possible or sometimes impossible to preserve the authenticity of the ecosystem in small areas, especially in a biological way.
