The National Biodiversity Authority (NBA), under the Ministry of Environment, Forest and Climate Change, has issued a Standard Operating Procedure (SOP) for the notification of threatened species under Section 38 of the Biological Diversity Act, 2002. The SOP aims to provide a uniform, transparent and scientifically robust process for the identification, assessment and notification of threatened species by States and Union Territories. India is among the most biodiverse countries, yet species are increasingly endangered due to habitat degradation, over-exploitation, pollution, invasion by alien species and climate change. Section 38 empowers the Central Government, in consultation with the concerned State Government, to notify any species that is on the verge of extinction or likely to become extinct in the near future as a threatened species, regulating or prohibiting its collection and prescribing measures for its rehabilitation and conservation; these powers may also be delegated to State Governments. So far, the Ministry has notified 159 plant species and 173 animal species relating to 17 States and 3 Union Territories. The SOP assists State Biodiversity Boards and UT Biodiversity Councils with a clear step-by-step framework covering scientific assessment, stakeholder consultation, verification, notification, conservation planning, monitoring and periodic review. It promotes the use of the best available scientific evidence, field-based assessments and traditional knowledge, ensuring participation of local communities, Biodiversity Management Committees, the Botanical Survey of India, the Zoological Survey of India, academic institutions and subject experts. The initiative gains significance in light of the Biological Diversity (Access and Benefit Sharing) Regulation, 2025, which provides differential treatment in benefit-sharing for species declared threatened under Section 38. The SOP supports the National Biodiversity Strategy and Action Plan 2024-2030 (especially Target 4) and the Kunming-Montreal Global Biodiversity Framework.
