Formation and Function of Biodiversity Management Committees (BMCs):
- Local bodies, under the guidance of BMCs, collaborate with communities to develop PBRs, ensuring the inclusive participation of locals in biodiversity conservation efforts.
Importance and Benefits:
- PBRs are pivotal in facilitating conservation efforts, sustainable resource management, and the preservation of traditional knowledge.
