According to the UNESCO MAB zoning model for Biosphere Reserves:
- Core Zone: The strictly protected, inviolate natural area dedicated entirely to the conservation of habitats, species, and genetic variation. No human activity, settlement, or commercial exploitation is permitted, except strictly regulated, non-destructive scientific monitoring.
- Buffer Zone: Surrounds the core area where low-impact activities like research, education, controlled ecotourism, and managed grazing are permitted.
- Transition Zone (Manipulation Zone): The outer zone where sustainable agricultural, settlement, and economic activities take place.
बायोस्फीयर रिजर्व के कोर जोन (Core zone) में किसी भी प्रकार के मानवीय हस्तक्षेप, निवास या वाणिज्यिक दोहन की अनुमति नहीं होती है; यह क्षेत्र पूरी तरह से प्राकृतिक व वन्यजीव संरक्षण के लिए आरक्षित एवं अनुल्लंघनीय (inviolate) होता है।
