Conservation Regime
BORDERS OF THE SPECIAL NATURE RESERVE AND THE PROTECTED AREA
When considering the use of the reserve’s resources, human activities must not endanger the ecological characteristics of the area. Total area of conservation stretches on 5480 ha 94 a 04 m2.
Three levels of protection regime have been established in the Reserve:
- 1 Potection regime of the first degree covers 165 ha 75 and 90 m2 or 3.02%
- 2 Protection regime of the second degree covers 3160 ha 78 and 75 m2 or 57.67%
- 3 Protection regime of the third degree covers 2154 ha 39 and 39 m2 or 39.31%.
The total area of the protection zone equals to 4143 ha. For the purpose of integral protection and preservation of ecosystem connections and all distinctive natural assets of the reserve, three levels of protection have been established. In the entire area of the Special Nature Reserve “Okanj bara” the following is strictly prohibited: hydromelioration (drilling wells, construction of canals and irrigation systems), construction – except for works that are in the function of improving the ecological conditions of habitats; researching of the natural resources, as well as other types of activities which change the basic characteristics of the habitat; construction of buildings, except for shepherds’ huts and sheep pens; grazing pigs; afforestation of habitats and placing landfills, as well as garbage disposal. This ensures the permanent monitoring of the condition and improvement of all types of habitats, ecosystems plant and animal species, especially natural rarities.
PROTECTION REGIME OF THE FIRST DEGREE
1. The use of natural resources and the construction of facilities are prohibited.
2. Works and activities are limited to:
1) Scientific research and monitoring of natural processes;
2) Controlled visit for educational, recreational and cultural purposes.
3) Implementation of protective, remedial and other necessary measures in case of fire, natural disasters and accidents, occurrence of plant and animal diseases and overpopulation of pests;
4) Intervention measures for the protection of ecosystems under special conditions for nature protection.
