Biosphere reserves are special territories with ecosystems that hadn’t feel a lot of human’s influence and are very close or are as natural as they had been before the appearance of humans. They represent an important subject of concern both of public and scientific, as they can be considered to be “as living laboratories” that show the high, natural level of interaction both of animal world, with flora, land and natural phenomena. Biosphere reserves are recognized by world authorities and they are under the jurisdiction of the countries, on which territories they are situated. The unity and integrity of these territories is guaranteed and protected by the laws of each particular country. Every biosphere reserve has a purpose of fulfilling the following functions: A conservation function which is the most essential, as its duty is to preserve the ecosystem in the way it had existed for a long time; A development function answers for the development of human interaction with nature, improving the natural processes and promoting preservation of it as well as playing an educating role in human’s consciousness about the importance of keeping nature preserved; And the last one the logical function which has it’s duty to secure and guarantee the research, constant study of the ecological system, its monitoring and scientific cooperation with specialists from another countries. Biosphere reserves are divided into three major areas: which are the core zone, the buffer zone and transitional area.

It’s essential for the core area to be correctly established and be protected by the laws, so that it’ll be guaranteed a long-term protection to the whole ecosystems including flora, fauna, environment and entrails. Understandably it should not be the object of the man’s activity because any influence of the weak chain of ecosystem can be the result of future constant damaging to the whole system. The only activity that can be allowed is exploration and scientific monitoring of the natural processes that take place in the environment. Buffer zones are defined as the areas that surround the core zones, or that are situated very closed to the core areas. The activities that are allowed in such areas don’t prohibit human activity, but more over they are directed on the conservation of nature and scientific research, to explore the natural vegetation conditions, animals monitoring and care, etc. These areas can be used for educational purposes, recreation and leisure as well as for tourism. An outer transition area can be used for the basic needs of rural settlements. It's often the areas used for agriculture, farming, and rural settlements. The conditions allow here more freedom of activities than in other areas of the biosphere reserve but still leave an important place for nature monitoring and protection. Outer transitional areas are the subject for the cooperation of both local communities as farmers and scientific authorities and ecologists for the development of the management strategies for both improving the rural conditions of life and development of communities as well as for taking measures to protect the environment and it’s the subject of further hard work of seeking for desired balance between nature and human expansion. This zonation division is used in various ways in the real world to adjust geographical, social and cultural particularities, as well as legal protection of the environment and to find probable ways of solutions for many environmental issues. The abilities of zonations to adjust and adopt new conditions allow the integrated functioning of the biosphere reserve. Dividing the territories into such zones of different level of protection people at the same time are trying to use those territories left for agriculture and farming in the most rational way, as well as to do the best to study and explore territories under protection for future proper functioning and solving issues that have any kind of damage to the ecosystems on the early stages of their spread and development.
