Answer: Sunderbans Tiger Reserve
Notes: On 19 August 2025, Sundarbans in West Bengal became India’s second-biggest tiger reserve after the National Board of Wildlife (NBWL) approved its expansion. The reserve area increased by 1,044.68 sq km, taking the total to 3,629.57 sq km, just behind Andhra Pradesh’s Nagarjunasagar-Srisailam Tiger Reserve (3,727.82 sq km). Three tiger-inhabited ranges in South 24 Parganas — Matla, Raidighi, and Ramganga — were added. The expansion, cleared by the National Tiger Conservation Authority (NTCA) earlier, brings all tiger-bearing mangroves under unified management.
