Biosphere reserves are areas of terrestrial ecosystems which are internationally recognized within UNESCO program Man and the Biosphere (MaB) for promoting and demonstrating a balanced relationship between people and nature. Biosphere reserves serve to combine the three following functions: conservation of landscapes, ecosystems, species and genetic variation, development – fostering economic development which is ecologically and culturally sustainable, logistic support – research, monitoring, training and education related to local, regional, national and global conservation and sustainable development issues. Each reserve is divided into zones defined by various activities corresponding to these three functions: core area, buffer zone and transition area. A national park may be divided into three management zones and landscape protected area into four zones. The principle of zonation in biosphere reserve and in national park is different.
