Practice question

Biosphere reserve zonation under UNESCO Man and Biosphere design includes three concentric management zones. Core zone constitutes strict nature reserve, typically existing national park or sanctuary, fully protected from anthropogenic disturbance, permitting only research and monitoring. Genetic resources remain undisturbed here to preserve evolutionary processes. Buffer zone surrounds core, allowing limited activities like education, ecotourism, traditional resource use by communities. This strict protection core ensures viability of endangered species and baseline ecological data for long-term studies. Such details are high-yield for NEET and CUET as they link morphological classification with modern molecular phylogeny insights.
