Tiger Corridor Connectivity in Central Indian Highlands: Forest Fragmentation, Linear Infrastructure and NTCA Guidelines
NEWS PEG
- The National Tiger Conservation Authority (NTCA) and Wildlife Institute of India (WII) released an updated landscape assessment on the Central Indian Tiger Landscape, highlighting severe gene-flow constriction between Kanha, Pench, Bandhavgarh, and Tadoba tiger reserves.
- The report noted that while India hosts over 75% of the world's wild tigers (3,682 individuals), genetic isolation due to widening four-lane highways, thermal power plants, and open-cast coal mines in corridor forests threatens long-term meta-population survival.
- NTCA mandated the creation of legally enforceable Eco-Friendly Linear Infrastructure measures (wildlife underpasses, canopy bridges) across all 32 identified national tiger corridors.
STATIC FOUNDATION
- Project Tiger (1973) / NTCA: Statutory body constituted under Section 38L of the Wildlife (Protection) Act, 1972 (amended 2006) for overseeing tiger conservation and declaring Tiger Reserves.
- Tiger Reserve Structure: Comprises a Core/Critical Tiger Habitat (notified under Section 38V of WPA - inviolate area free from human exploitation) and a Buffer/Peripheral Area (fosters co-existence between wildlife and human activity).
- Central Indian Landscape: Spans Madhya Pradesh, Maharashtra, Chhattisgarh, Odisha, and Rajasthan; represents the largest contiguous tiger habitat and highest meta-population genetic diversity in the world.
- M-STrIPES (Monitoring System for Tigers - Intensive Protection and Ecological Status): Android-based patrolling and spatial monitoring tool used by forest guards across all tiger reserves.

MAINS ENHANCEMENT
- Meta-Population Genetic Health: Preserving Wildlife Corridors — Ensuring continuous gene flow between tiger populations to prevent inbreeding depression.
- Linear Infrastructure Mitigation: Eco-Duct Engineering along NH-44 (Kanha-Pench) — Demonstrating the success of dedicated animal underpasses in eliminating roadkill.
- Community-Led Co-existence: Voluntary Village Relocation with Fair Compensation — Securing inviolate core zones while investing in buffer zone eco-development committees (EDCs).
