Nature and landscape protection have undergone the development that is also reflected in the Act of National Council of the Slovak Republic, No 287/1994 On Nature and Landscape Protection. Besides, it provides general area protection throughout Slovakia at the first and lowest level. Protected landscape areas, Slovak national parks present a significant part in the protection of environment.

The scientific research is realised throught the methods of landscape-ecological analyses and syntheses. There are reflected reciprocal circumstances of abiotic and biotic factors of landscape in connection with its topical use and protection, and resulting in the proposal for optimum use.
