North Bengal's Tea Estates Now Have Far Less Razor Wire in Elephant Corridors. Here’s What Changed

Razor-wire fencing became far less widespread around the assessed North Bengal tea-estate landscape between 2019 and 2026. Its mapped length dropped from approximately 134.7 km to 34.8 km. This matters because sharp fencing had obstructed elephant routes, caused serious injuries, and sometimes killed animals trying to cross.

The change followed years of discussion and fieldwork by the Wildlife Trust of India and SPOAR. A 2019 survey examined eight elephant corridors and documented barriers inside tea estates. Later meetings involved estate managers, workers, communities, the Forest Department, tea associations and administrators. Some estates agreed to remove razor wire or leave routes open.

The reduction does not mean every fence was intentionally removed. WTI attributed it to removal, deterioration and fencing not being reinstalled. Even so, the figures show that fencing practices changed over time. The reassessment also found low-hanging power lines, showing that safer movement requires more than removing razor wire.

Across the assessed tea-estate landscape, razor-wire fencing dropped from approximately 134.7 km in 2019 to 34.8 km in 2026. That is a reduction of about 99.9 km, or 74.2%. The change is important because razor wire was identified as a particularly sharp and dangerous barrier on elephant movement routes.

Total mapped fencing also declined, from 291.7 km to 104.5 km. That is a fall of 187.2 km, or about 64.2%. The two measures are different: total fencing includes fencing of various kinds, while the razor-wire figure isolates one material. Razor wire therefore declined more sharply as a proportion of its original length.

The figures measure physical barriers, not outcomes for people or elephants. WTI said the reduction reflected removal, deterioration and fencing not being reinstalled. The data do not prove how many injuries or human-elephant encounters were prevented, but they show a substantial change in the mapped fencing landscape.

An elephant corridor is a connected route that allows elephants to move between habitats. In North Bengal’s Terai and Duars, such routes extend beyond forest boundaries. They may pass through forest patches, tea plantations, worker settlements, roads and railway lines. These connections matter because elephants need to move across a wider landscape in search of food, water and space.

A tea plantation can therefore form part of an elephant’s familiar passage. WTI and SPOAR’s year-long 2019 survey covered eight identified corridors and recorded how elephants used tea estates. The survey also documented barriers that could impede movement. A route through Meenglass Tea Estate, within the Apalchand-Kalimpong corridor, was recorded by camera traps in 2024.

The reassessment shows why corridor protection cannot focus only on forests. Fences, trenches and other obstacles can break connections across working landscapes. Keeping routes open through tea estates can help preserve movement between habitats, while reducing the chance that diverted herds enter settlements or other risky areas.

Tea-estate fencing may be intended to protect workers, crops and property. But when it cuts across an elephant movement route, it can make a familiar passage dangerous or unusable. Elephants may face sharp wires, trenches or other barriers instead of an open route. This creates risks for wildlife and for people living or working nearby.

WTI reported that randomly installed razor-blade fencing forced herds to divert from their usual routes. The wires caused serious injuries to elephants and other wildlife, and some animals died while attempting to cross. When elephants cannot follow established paths, their movement may bring them closer to labour lines, roads and settlements.

The risk is therefore indirect as well as direct. A fence can injure an elephant at the barrier, or redirect a herd into places where people and animals meet more closely. The 2019 survey and later consultations focused on identifying problematic barriers, keeping routes open and reducing losses for both communities and elephants.

The change involved more than one organisation. WTI and its conservation partner, SPOAR, led surveys, meetings and continuing engagement. Tea-estate management, the Forest Department, tea associations, administrators, local communities, workers and conservation organisations also took part. Their shared focus was safer elephant passage through tea gardens.

In 2019, WTI and SPOAR surveyed eight corridors and identified barriers. On World Elephant Day, nearly 50 representatives joined a consultative workshop. Discussions covered problematic fencing, open movement routes and ways to reduce losses. Some estate representatives described areas already left open, while others committed to removing razor wire or avoiding it in future.

Engagement continued through awareness initiatives and discussions with workers and residents. By 2026, mapped razor wire had fallen from approximately 134.7 km to 34.8 km. The decline reflected removal, deterioration and fencing not being reinstalled. The work also points to a continuing need for cooperation, because other hazards remained across the landscape.

The fall in razor wire shows that a physical barrier became less extensive, but it does not directly measure what happened to elephants or people. The 2026 reassessment recorded fencing lengths. It did not verify how many elephant injuries, deaths or human-elephant encounters were prevented during the period.

The reason is also important. WTI attributed the decline to a combination of deliberate removal, deterioration and fencing not being reinstalled. Therefore, missing wire does not always represent a planned safety improvement. A fence may have disappeared without a documented change in animal movement or risk.

The figures still matter because they indicate that estate practices changed after sustained engagement. But they should not be treated as casualty statistics. The landscape may contain other hazards, including low-hanging electrical infrastructure. Measuring safer outcomes would require separate evidence about injuries, encounters and movement after barriers changed.

Removing a fence does not automatically make an elephant route safe. Elephants may still encounter other obstacles across a connected landscape. The 2026 reassessment identified low-hanging electrical infrastructure as a serious concern, showing that hazards can exist above the route as well as across the ground.

The survey documented 54 power lines below a height of 13 feet. Nearly half, 47.4%, hung below 10 feet. These measurements matter because the lines were flagged as serious hazards to elephants. Thus, an open passage through a tea estate may still contain dangerous infrastructure that needs attention.

The findings broaden the work required after fencing changes. WTI, SPOAR, government agencies and estate managers would need to consider overhead lines alongside fences, trenches and other barriers. The article does not provide a verified count of electrical injuries or describe corrective work. It does show that connected movement depends on addressing multiple hazards, not razor wire alone.
