Linear infrastructure and plantation economies fragment wildlife corridors. Suggest a framework to reconcile development with landscape-level conservation.

The NTCA and the Wildlife Institute of India (WII) have mapped 32 major tiger corridors that connect India's reserves [2]. Roads, railways, canals, power lines and plantation estates increasingly cut through these corridors. This turns protected areas into isolated "islands". Development and conservation can coexist only if planning moves from reserve boundaries to whole landscapes.

How fragmentation harms wildlife

• Linear infrastructure kills animals directly through collisions and electrocution. Its noise and light also change how animals move, and isolation lowers the long-term viability of populations [3].
• Plantation economies (tea, coffee, monoculture estates) replace corridor forest with land that animals cannot easily cross. In landscapes like North Bengal's Dooars, tea gardens and railway tracks lie across elephant routes. Railways are now extending intrusion-detection systems to sensitive sections in North Bengal [4].
• Result: gene flow is cut off, human-wildlife conflict rises, and reintroduction efforts fail because the animals cannot disperse.

Suggested framework: Plan → Avoid → Mitigate → Share → Monitor

Landscape plan → Avoid corridors → Mitigate crossings → Share with estates/people → Monitor & audit

Fig: Hierarchy for reconciling development with connectivity

• Plan: Make each reserve's Tiger Conservation Plan (Sec. 38V, WPA 1972) cover the whole landscape, as the 2006 tiger chapter intended [1]. Corridor interventions should run through these plans [2]. Overlay corridor maps on all road and rail master plans.
• Avoid: Re-route new roads and railways away from critical corridors. Assess the cumulative impact of all projects in a landscape, not one project at a time.
• Mitigate: Make WII's 2016 "Eco-friendly Measures" guidance mandatory: underpasses, overpasses, signage and speed limits [3]. On the Delhi–Dehradun corridor, animal underpasses and a 12-km elevated stretch are now used by 18 wild species [5]. Indian Railways has sanctioned AI-based intrusion detection (Gajraj) for 1,158 route-km [4].
• Share: Give plantation owners incentives such as payments for ecosystem services to keep corridor patches and shade trees. Any relocation must be voluntary, under the WPA read with the Forest Rights Act, 2006 [6]. Build up the prey base and pay prompt compensation to reduce conflict [7].
• Monitor and govern: Set up joint railway–highway–forest committees under the CM-chaired State Steering Committees [1]. Audit crossing structures regularly with camera traps.

Corridors are where infrastructure, plantations and people meet the needs of wildlife. A clear sequence of plan, avoid, mitigate, share and monitor, backed by law, turns that conflict into "development with caution" [3]. This is in line with Article 48A and SDG 15 (Life on Land), and it lets India's growth corridors and wildlife corridors run side by side.
