India's highway authority restores mangrove wetlands in Tamil Nadu

The National Highways Authority of India (NHAI) and the Tamil Nadu Forest Department have successfully planted mangroves across 25 hectares in the Pichavaram wetland ecosystem, marking a significant step in environmental restoration efforts. The plantation drive was undertaken as a compensatory measure for mangrove destruction during road widening operations.

According to officials familiar with the project, the restoration initiative was prompted by damage to approximately 15 square metres of mangroves in Marakkanam during highway expansion work. Rather than allowing the loss to remain unaddressed, the NHAI initiated the large-scale replanting programme in consultation with forest authorities.

The Pichavaram wetlands, situated along Tamil Nadu's Coromandel coast, represent one of India's most ecologically significant mangrove ecosystems. These coastal forests serve as critical habitats for numerous fish and bird species while providing essential protection against tidal surges and coastal erosion.

The collaborative approach between the highway authority and forest department reflects growing recognition among infrastructure developers of the need for environmental stewardship. Officials indicated that such compensatory afforestation efforts are becoming standard practice for major road development projects in environmentally sensitive zones.
