Siliguri Corridor Infrastructure Impacts Elephant Habitats

The Siliguri Corridor, known as the Chicken’s Neck, is the only land route connecting India to its eight northeastern states. This 22-kilometer-wide strip is a critical transit hub featuring extensive road, rail, and pipeline networks that pass through sensitive ecological zones connecting the Mahananda Wildlife Sanctuary to the Baikunthapur and Chapramari forest areas.

Railway Operations and Wildlife Safety

Since the gauge conversion between New Jalpaiguri and Alipurduar, the railway route has frequently become a site of wildlife accidents. Heavy freight trains and night passenger services regularly cross established migration paths, leading to fatal collisions involving Asian elephants, leopards, and gaur. Although speed limits are set between 25 and 30 km/h, these rules are often ignored by freight operations that aim to clear supply chain bottlenecks in the north.

Infrastructure Obstacles for Wildlife

Forest rangers working along the tracks have reported that fragmented communication systems and steep track-side ballast embankments prevent animal herds from moving away from approaching trains. These physical barriers make it difficult for animals to escape oncoming locomotives when crossing the tracks. The current environment presents a significant challenge for the safety of wildlife populations moving through the forest patches.

Proposed Solutions for Habitat Connectivity

While pilot programs for optical-fiber-based Intrusion Detection Systems are currently underway, conservationists have highlighted the need for more permanent solutions. Experts suggest that the construction of dedicated underground eco-ducts or the rerouting of heavy freight trains via the southern mainline is necessary. Without these changes, further infrastructure development threatens to permanently disconnect the transboundary elephant corridor.
